    1 Introduction

    Open any introductory anthropological textbook and

    its likely that among the groups exemplifying a

    hunter-gatherer lifestyle will be one or other of the

    Bushman peoples of southern Africa1. Read further

    into the debates surrounding the pristineness of

    surviving foragers and once again Bushmen and

    their relations with pastoralist and farming

    neighbours figure prominently. Survey the literature

    dealing with the origins of anatomically modern

    humans or the development of modern behaviour

    and key southern African sites such as Klasies

    River Mouth, Border Cave and Blombos stand forth.

    Examine general overviews of rock art, including

    that produced by Upper Palaeolithic people in

    Europe, and the shamanistic understanding of

    southern Africas Bushman paintings and

    engravings will be discussed and frequently

    applauded for the richness of its insights. These

    are but some of the reasons why southern African

    hunter-gatherers and their past are of concern to

    anthropologists and archaeologists wherever they

    work.

    The past ten years have seen major political

    and economic changes in southern Africa. These

    changes are now impacting on how archaeological

    research is carried out in the sub-continent.

    Meanwhile, hunter-gatherer archaeology has itself

    undergone something of a reorientation. New

    research questions have come to the fore, some

    longstanding projects have been published or

    brought to a conclusion and several others initiated.

    This paper has two objectives. First, to take stock

    of what has happened over the last decade,

    assessing the gains made and identifying the

    principal directions along which research has

    proceeded. Having done this, the paper moves on

    to ask where hunter-gatherer archaeology in

    southern Africa is, and should be, moving, where,

    in other words, can we expect the next ten years

    to lead us?

    No single paper can do justice to all of the work

    that has been, or is being, carried out in southern

    Africa, and it is therefore important to establish at

    the outset the temporal and geographical limits of

    this survey. Chronologically, I take the view that

    Abstract

    Southern Africa has become a major focus for international hunter-gatherer research, partly because of the

    prominence accorded surviving Bushman peoples in the anthropological literature, partly because of recent

    advances in understanding the origins of anatomically modern humans and the meaning of Bushman rock

    art. This paper surveys the principal developments in hunter-gatherer archaeology within the region over the

    past decade and identifies the key themes that have been pursued. It then attempts to indicate the main

    directions along which research may grow over the next several years.

    Hunter-gatherer archaeology in southern Africa: Mitchell

    hominins were undertaking anything like the same

    range and complexity of behaviours as recent or

    contemporary populations. Nor, it is clear from

    the fossil evidence, were they anatomically

    modern. The temporal range of the paper is thus

    restricted to the Middle and Later Stone Ages, or

    approximately the last 200,000 years. Spatially,

    there are good reasons - ecological, cultural and

    archaeological - for thinking of that part of Africa

    south of the Zambezi and Kunene Rivers as a unit.

    Its boundaries were clearly not impermeable or

    fixed, especially perhaps in the west.

    Nevertheless, the distributions of rock art styles,

    stone tool industries and even of historically

    documented Khoisan-speaking populations fit

    broadly within it. The areas covered here are thus

    those included within the modern states of

    Botswana, Lesotho, Namibia, South Africa,

    Swaziland and Zimbabwe, along with the southern

    half of Mozambique (figures 1, 2).

    The most recent overview of hunter-gatherer

    archaeology across this wide region is that of HJ

    Deacon & J Deacon (1999). More detailed

    syntheses cover areas south of the Limpopo River:

    A Thackeray (1992) for the Middle Stone Age

    (MSA), Wadley (1993) for the Pleistocene Later

    Stone Age (LSA) and Mitchell (1997) for the

    Holocene LSA until c 2000 BP. Botswana is well-

    served by papers in Lane et al (1998). Walker &

    Thorp (1995a) summarise work in Zimbabwe and

    Kinahan (1991) and Vogelsang (1996) provide

    overviews of LSA and MSA archaeology in

    Namibia.

    2 Hunter-gatherer archaeology in southern

    Africa: the past decade

    In attempting to summarise where research has

    concentrated since 1990 and what it has achieved

    several approaches are possible. That chosen

    here emphasises some of the themes that

    researchers have pursued, rather than particular

    geographical locales or even more narrowly

    conceived temporal divisions. Rock art is not

    discussed in detail as it forms the subject matter

    of a forthcoming article in this journal.

    2.1 Anatomically and behaviourally modern humans

    The past decade has seen major advances in our

    understanding of the origins and spread of

    anatomically modern humans. In southern Africa

    three interrelated developments are important:

    clarification of the status and publication of key

    fossil specimens; a tighter chronology; and the

    expansion of research to new sites. Excavation of

    surviving deposits at the complex of interconnected

    shelters at Klasies River Main Site (figure 3) has

    made the largest contribution to the first two of

    these developments. Reassessment of the whole

    Klasies fossil assemblage shows that it falls within

    the range of variation typical of modern humans

    (Rightmire & Deacon 1991; Bruer et al 1992), even

    if some specimens are surprisingly robust

    (Churchill et al 1996), suggesting a mosaic

    evolutionary pattern in which cranial and postcranial

    elements evolved at different rates. Although

    individual finds occur later in the Klasies sequence,

    most are tightly dated using uranium-series, ESR

    and amino-acid racemisation to c 90,000 BP (HJ

    Deacon & Schuurman 1992). Two upper jaw

    fragments from an older occupation c 120,000 BP

    are among the oldest firmly dated anatomically

    modern specimens known (HJ Deacon 1995).

    Figure 3 Klasies River Main Site, Eastern Cape Province, South Africa

    At the same time studies of bone diagenesis

    have suggested that the infant skeleton and adult

    mandible from Border Cave (figure 4) are intrusive

    into the MSA levels in which they were found (Sillen

    & Morris 1996), although this conclusion has

    recently been contested by Grn & Beaumont

  • 4 Before Farming 2002/1 (3)

    Hunter-gatherer archaeology in southern Africa: Mitchell

    (2001). Since other human material from this site

    has been found out of its original context, Border

    Caves relevance to debates on anatomically

    modern human origins is thus considerably

    reduced. On the other hand, renewed excavations

    at Die Kelders (Grine et al 1991; Grine 1998) and

    investigations of a new and very important site at

    Blombos (Grine et al 2000) have produced several

    teeth, which share most of their attributes with

    modern African populations. ESR and

    luminescence determinations suggest ages for

    these specimens of 60-80,000 and around 100,000

    years ago respectively. Finally, the clearly more

    archaic cranium from Florisbad has had its age

    pushed substantially back, again using ESR, to

    around 260,000 BP (Grn et al 1996). It thus takes

    its place alongside other southern African Middle

    Pleistocene fossils (Kabwe, Elandsfontein, etc), as

    one of several sub-Saharan examples of long term

    morphological continuity between H ergaster and H

    sapiens, a continuity much more difficult to sustain

    in other regions of the Old World (Rightmire 2001).

    Figure 4 View west from the Lubombo Escarpment near Border Cave

    into Swaziland (courtesy, Peter Beaumont)

    Together, these specimens and their

    accompanying dates provide an increasing body

    of data that supports the case for a recent sub-

    Saharan origin for modern humans, a case

    independently argued from a variety of genetic

    evidence (Kittles & Keita 1999). Recent estimates

    for the origin of mitochondrial DNA diversity in

    modern humans point to the period 100-200,000

    years ago (Erlich et al 1995; Goldstein et al 1995;

    Ruvolo 1996), the same time range within which

    anatomically modern humans first appear in the

    sub-Saharan fossil record. Whether behavioural

    patterns recognisably the same as those found in

    recent and present day human societies emerged

    concurrently with, or followed, these changes

    remains a matter of debate (most recently reviewed

    by McBrearty & Brooks 2000).

    And this is a debate to which southern African

    evidence is again increasingly contributing. The

    dating techniques already mentioned are beginning

    to provide the much tighter chronological framework

    for the MSA that is a sine qua non for meaningful

    inter- and intra-site comparisons. Though some

    remain experimental and they do not always

    produce congruent results, a glance at table 1

    shows the impact that they have had over the past

    ten years. In particular, the consensus of dates

    from Border Cave, Klasies River and Diepkloof

    points to the distinctive Howiesons Poort

    assemblages, with their many backed pieces and

    tendency to use finer-grained rocks, falling firmly

    within the period 60-70,000 BP; younger

    radiocarbon dates almost certainly reflect

    contamination (J Deacon 1995). The Howiesons

    Poort has long attracted attention because of its

    superficial similarities to the Wilton industry of the

    middle and later Holocene, as well as for what was

    once thought to be its intrusion into a longer, more

    static MSA sequence (Singer & Wymer 1982).

    Restudy of assemblages from Klasies River Main

    Site (A Thackeray 1989; Wurz 1999), and work

    elsewhere (Kaplan 1990; Harper 1997), show

    instead that it cannot be separated from the rest of

    the MSA stoneworking tradition. Nor is it the only

    example of time-restricted patterning within the

    MSA. Indeed, at Die Kelders the 60-70,000 BP

  • Before Farming 2002/1 (3) 5

    Hunter-gatherer archaeology in southern Africa: Mitchell

    assemblages contain only informally retouched,

    mostly denticulated pieces, rather than Howiesons

    Poort type backed artefacts (A Thackeray 2000).

    Unless the two toolkits reflect differences in activity,

    we may be looking at genuine regional variations

    in material culture that may be stylistic in origin.

    Evidence of distinctive chronological patterning

    within the MSA also comes from excavations at

    Blombos, a cave site near Stillbay on South Africas

    Indian Ocean coast, that has provided several

    exciting new finds during the past decade. The MSA

    sequence here is divisible into three phases, the

    uppermost marked by pressure-flaked foliate

    Stillbay points, found here for the first time in

    stratigraphic context. Equally startling was the

    recovery of well over 20 worked bone tools, including

    points indistinguishable technologically from those

    made during the Holocene. These concentrate in

    the middle phase at Blombos, in which Stillbay

    points are rare, and are preceded by a further phase

    with typical MSA flakes and blades and few

    retouched artefacts (Henshilwood & Sealy 1997;

    Henshilwood et al 2000). The Stillbay levels

    probably have a minimal age of 70,000 BP and

    also produced an intentionally engraved fragment

    of bone (dErrico et al 2001). Along with engraved

    pieces of ochre from the same site, others from

    Hollow Rock Shelter in the Cederberg Mountains

    (Evans 1994) and AMS-dated fragments of incised

    ostrich eggshell from Diepkloof (one at least of

    which dates to > 40,000 BP; Parkington 1999),

    this find raises the possibility that southern Africa

    witnessed the deliberate investment of symbolic

    meaning in material culture substantially earlier

    than anything seen in Upper Palaeolithic Europe,

    the traditional yardstick for such finds. Watts (1998)

    assessment of MSA ochre use, showing a sharp

    jump in frequency after 127,000 BP and evidence

    for colour selection, makes the same point.

    Other archaeologists have sought modern

    cognitive capacities in the organisation of space

    within occupation sites and in the exploitation of

    plant and animal resources. Neither strategy,

    however, has met with great success, perhaps

    Hunter-gatherer archaeology in southern Africa: Mitchell

    because with this kind of evidence it is much more

    difficult to establish how modern cognitive abilities

    might be displayed. Consistencies in hearth

    positioning and shellfish dumping in MSA levels at

    Klasies River (Henderson 1992; HJ Deacon 1995)

    may, for example, reflect no more than purely

    functional considerations, as may the patterns of

    stoneworking and butchery from the much larger

    excavations at the Florisbad open-air site (Brink &

    Henderson 2001). Modification of living sites, as

    found at Mumbwa, Zambia (Barham 2000), has also

    yet to be convincingly demonstrated south of the

    Zambezi. On the other hand, there is now

    increasingly solid evidence (pace Klein & Cruz-

    Uribe 1996) that MSA people sometimes caught

    fish, both on the coast at Blombos (Henshilwood

    & Sealy 1997) and inland at White Paintings

    Shelter, northern Botswana (Robbins et al 1994).

    Milos (1998) reanalysis of the Klasies River fauna

    has also confirmed that MSA people actively hunted

    the full range of bovids, including giant buffalo

    (Pelorovis antiquus), implying a sophisticated

    knowledge of animal behaviour. But fuller

    understanding of MSA subsistence strategies and

    the degree to which MSA people employed material

    culture symbolically remains constrained by the

    low density of well-excavated sites with good

    organic preservation and by the historic emphasis

    on the southern littoral of the Cape Fold Mountain

    Belt. Excavation of new sites is necessary, nowhere

    more so than in Namibia, where only recently has

    earlier fieldwork been published (Vogelsang 1996),

    and Zimbabwe, where well-excavated MSA

    sequences are virtually lacking (Larsson 1996). It

    is thus appropriate to end this section by drawing

    attention to several recently initiated projects:

    excavation and survey of new MSA sites on South

    Africas Atlantic coast (Conard et al 1999; Klein

    1999; Parkington 1999; University of Tbingen

    2001); the reinvestigation of Howiesons Poort levels

    at Diepkloof, Western Cape (figure 5; University of

    Bordeaux 2001); exploration of additional open-air

    sites in the Free State (Churchill et al 2000; Brink

    & Henderson 2001); and the excavation of Sibudu

    Shelter, KwaZulu-Natal, where an extensive

    sequence of deposits with well preserved charcoals,

    macroplants and bone may reach back 200,000

    years (University of the Witwatersrand 2001).

    2.2 Exploring social relations

    If the Middle Stone Age has attracted considerable

    attention over the past ten years, this is less true

    for the remainder of the Pleistocene.

    Figure 5 Diepkloof Shelter, Western Cape Province, South Africa

    The transition from MSA to LSA technologies

    in particular remains little studied, although the

    earlier notion of quite informal microlithic

    assemblages (the so-called Early Later Stone Age

    or ELSA; Beaumont 1978) extending back to 40,000

    years ago now seems implausible (Wadley 1991).

    Instead, MSA stoneworking techniques continued

    in use until at least 25,000 BP, if not slightly later,

    across much of southern Africa (Mitchell 1994; HJ

    Deacon 1995; Wadley 1997a). A multiplicity of

    pathways may have led into the adoption of the

    earliest LSA traditions, which perhaps appeared

    rather earlier in northern Botswana (Robbins 1999).

    A more contextual approach to understanding these

    changes is necessary, one not handicapped by a

    simple, dualistic typological straitjacket (Mitchell

    1994; Clark 1999). The study of chanes

    opratoires, something recently pioneered for

    Howiesons Poort and other MSA assemblages

    (eg, Wurz 1999), and more detailed considerations

    of how technologies were organised and employed

    may prove helpful. But what seems already clear

    is that the MSA/LSA transition was primarily an

    issue of lithic technology. It does not equate with

    the shift from Middle to Upper Palaeolithic in western

  • Before Farming 2002/1 (3) 7

    Hunter-gatherer archaeology in southern Africa: Mitchell

    Eurasia. The well-known painted slabs from Apollo

    11 Cave, found with a terminal MSA assemblage

    dating c 27,000 BP (Wendt 1976), make this point,

    while jewellery occurs in still older contexts: ostrich

    eggshell beads, for example, are present at Border

    Cave by 38,000 BP (Beaumont 1978; Vogel et al

    1986) and, along with containers of the same

    material, are directly dated to 26-32,000 years ago

    at White Paintings Shelter (Robbins 1999).

    Based more on re-evaluating earlier work than

    upon new data as such, southern African

    archaeologists are now downplaying contrasts in

    settlement-subsistence strategies between late

    Pleistocene and Holocene LSA populations. Both

    may have been largely patch-bound foragers

    primarily dependent upon plant foods, though

    undoubtedly integrating specific resources in

    individual ways (HJ Deacon 1995), ways that will

    also have varied from one environment and

    landscape to another (Mitchell in press). What is

    less clear is the degree to which continuities in

    social relations can be traced back from the

    ethnographic present beyond the Pleistocene-

    Holocene transition and, indeed, into the MSA. This

    question is all the more pressing as hunter-gatherer

    archaeology in southern Africa has, over the last

    15 years, come to emphasise social and

    ideological, rather than predominantly ecological,

    themes.

    Addressing this issue, Wadley (1993) and J

    Deacon (1990) comment that the small number of

    bone points (= arrows ?) and ostrich eggshell

    beads, both popular gift exchange items among

    Kalahari Bushmen today, may mean that this

    practice was only weakly developed before 12,000

    BP. Since gift exchange, frequently referred to by

    its !Kung Bushman term as hxaro, is a central pillar

    structuring the social relations of many Kalahari

    foragers, the implication is that social relations were

    quite different before and after 12,000 years ago.

    But we should be careful here. Only in a few regions

    of southern Africa, such as much of Lesotho and

    KwaZulu-Natal, can we be reasonably certain that

    ostrich eggshell beads were moved at all, since

    elsewhere the ubiquity of ostriches means that they

    are not sourceable (Mitchell 1996). Furthermore,

    we have no real evidence for the antiquity of the

    bow and arrow, or the function of Pleistocene bone

    points. Parkington (1998), for example, opts for a

    date of c 9000 BP for the weapons introduction

    since no points or linkshafts of later Holocene form

    are present in the extensive terminal Pleistocene

    worked bone assemblage from Elands Bay Cave.

    The connections between hunting with bow and

    poisoned arrow and ethnographically documented

    Bushman beliefs about sex, gender and

    shamanistic trance would thus suggest many

    differences in social relations and ideology either

    side of 9000 BP (Parkington 1998; Wadley 1998).

    Regrettably, art, which could offer another means

    of assessing arguments for or against continuities

    in social structure and ideology, is virtually lacking

    before the middle Holocene; the few similarities in

    content observed by Lewis-Williams (1984)

    between the Apollo 11 paintings and recent rock

    art are too insubstantial to convince.

    Most of the effort directed toward investigating

    Mazels (1987) people-to-people questions is thus

    being targeted at the Holocene Later Stone Age.

    Foremost among the methodologies followed is the

    recognition that in order to research questions of

    social relations we must try and resolve time, place

    and person as clearly as possible. This, as

    Parkington (1998) and others have argued,

    demands a concomitant shift away from the often

    poorly-grained rock-shelter sequences and even

    less well dated surface scatters of artefacts that

    have hitherto dominated archaeological research

    strategies. In addition, it requires a concerted effort

    to deploy radiocarbon dating effectively, excavate

    sites microstratigraphically and, where the

    organisation of space is a concern, to dig them on

    a sufficiently large scale.

    Though still unpublished in detail, Elands Bay

    Cave (figure 6) offers one example of a site where

    the combination of these approaches allows the

    recognition of several reasonably discrete

    occupation episodes, among them are a mass

    stranding of rock lobster (Jasus lalandii) c 10,000

    BP, intensive exploitation of whelks (Burnupena sp)

    some 400 radiocarbon years later and the shortlived

    innovation and use, at least at this site, of bone

    fish gorges and Donax serra shell scrapers in the

    millennium thereafter (Parkington 1992). It is such

    high resolution phenomena that can most closely

    approximate in the prehistoric record the decisions

    of individuals within actual social and environmental

    contexts. The challenge, of course, is to multiply

    such examples across many sites and regions.

    One area where this has been attempted recently

    is the eastern Free State.

    Figure 6 Elands Bay Cave, Western Cape Province, South Africa,

    with the Atlantic Ocean at the far right

    Figure 7 Rose Cottage Cave, Free State, South Africa

    The principal focus of Lyn Wadleys (1995,

    1997a) work here has been Rose Cottage Cave (figure

    7), where spatial patterning has been examined over

    successive levels. Interestingly, in the light of our

    earlier discussion of MSA behavioural capacities,

    Wadley (1996a, 1997a, 2000a, 2000b) detects a

    much less structured use of space in the transitional

    MSA/LSA level G compared to overlying LSA

    occupations. However, the spread of dates and high

    artefact densities suggest that these layers may

    result from many repeated occupations, and it is

    uncertain whether the taphonomic processes

    involved are strictly comparable.

    Instead, it may be more productive to explore

    sites where the palimpsest effects of multiple

    occupations, which include vertical displacement

    of key finds (cf Sealy & Yates 1994) are absent or

    minimised. Strathalan in the northern Eastern

    Cape is one such site. Here Cave A contains the

    residues from two hunter-gatherer occupations,

    one some 300 years old (Opperman 1999), the

    other dating to c 2500 BP (Opperman 1996a). The

    adjacent Cave B contains a series of overlying

    terminal MSA occupations falling between 29,000

    and 22,000 years ago (Opperman 1996b;

    Opperman & Heydenrych 1990). At both sites the

    occupation surfaces, separated from each other

    by sterile sands, have a remarkable degree of

    organic preservation, including remains of edible

    plants and wooden artefacts. Open-air sites,

    where activities could have been conducted free

    from the constraints of rock-shelter walls, may

    be even more informative. Dunefield Midden on

    South Africas west coast, excavated by John

    Parkington and colleagues from the University of

    Cape Town, is the best example of this strategy.

    With over 500 m2 uncovered, the bulk of this site

    represents a single occupation c 650 BP, the

    initial impetus for which may have been a

    successful eland kill, though shellfish, seals and

    ground game were also exploited, along with a

    beached whale (Parkington et al 1992; Jerardino

    & Parkington 1993). The finely resolved

    stratigraphy permits detailed exploration of spatial

    patterning in the arrangement of hearths, shell

    dumps and meat-roasting pits, while refitting of

    bones offers scope for investigating meat-sharing.

    Kent (1998) offers a taste of what such analyses

    may eventually offer, while the much smaller, but

    repeatedly occupied, campsite at Likoaeng in

    Lesothos highlands (figure 8) demonstrates that

    high resolution open-air sites are not restricted to

    the coast (Mitchell & Charles 2000). Florisbad,

    and perhaps other open-air sites in the Free State,

    offer comparable opportunities for the MSA (Brink

    & Henderson 2001).

  • Before Farming 2002/1 (3) 9

    Hunter-gatherer archaeology in southern Africa: Mitchell

    To investigate social relations archaeologists

    have turned to the rich ethnographic data available

    for southern African hunter-gatherers. Recently, this

    evidence comes from the Kalahari Desert (Barnard

    1992), but it also includes nineteenth century

    records of the /Xam Bushmen of the Northern Cape

    compiled by Lucy Lloyd and Wilhelm Bleek (J

    Deacon 1996a). Lewis-Williams (1982)

    identification of the importance of shamans in the

    social reproduction of Bushman society and the

    likelihood that rock art played a key part in this in

    many areas of southern Africa have been pivotal in

    encouraging archaeologists to address people-to-

    people questions. Particularly through the work of

    Lyn Wadley (1987, 1997b), Aron Mazel (1989),

    Simon Hall (1990, 2000), Ann Solomon (1992, 1995)

    and John Parkington (1996, 1998), aggregation and

    dispersal patterns, gift exchange, gender relations,

    burial and the identification of past alliance

    networks have all emerged as important areas of

    study (Mitchell 1997, in press).

    Figure 8 Likoaeng, Lesotho

    But simultaneously there has been an

    enduring concern that these topics are

    outstripping the abil i ty of archaeological

    methodologies to keep pace (Barham 1992;

    Walker 1995a). In the Thukela Basin, for

    example, only with the excavation of Maqonqo

    Shelter (Mazel 1996) has the identification of

    distinct social regions (alliance networks) begun

    to incorporate the recognition that cultural

    systems are differentially organised and that

    people will have used different sites for different

    purposes or the same site for different purposes

    at different times (cf Parkington 1980). For the

    same reason a bipolar classification of site

    variability into either aggregation or dispersal

    sites, although encouraging the linkage of

    excavated material and rock art to support one

    or other identification (eg, Ouzman & Wadley

    1997), may blind us to other differences in site

    function.

    Whether creat ing social regions or

    designating sites as foci of aggregation or

    dispersal, archaeologists face the problem of

    how to assign meaning to the things they

    excavate. Far from becoming clearer, recent

    microwear and residue studies complicate this

    picture still further, at least as far as it relates

    to stone artefacts, many of which seem to have

    been used on a wide variety of materials or in a

    variety of ways (Wadley & Binneman 1995;

    Binneman & Mitchell 1997; Williamson 1997).

    Since many so-called unmodified (waste)

    pieces were also certainly used and we have

    virtually no southern African ethnography that

    relates to stone tool manufacture or use the

    challenges for determining how artefacts were

    employed and why they were designed the way

    they were are obvious. As Wadley (2000b)

    makes plain, we need to differentiate intra-

    regional differences in activity, whether or not

    subsistence related, from inter-regional

    differences in artefact style that may parallel or

    reflect kinship alliances, language groups or

    exchange networks. To give but two more

    specific examples, we must therefore establish

    whether and why particular kinds of retouch

    should have signalled social identity, instead of

    ref lect ing dif ferences in haft ing, use or

    resharpening (Barham 1992 pace Mazel 1989),

    and how we can best disentangle the effects of

    size, nature and duration of occupation in

    quant i fy ing f inds when at tempt ing to

    discriminate aggregation from dispersal sites (cf

    Walker 1995a with Wadley 1992a; Jerardino

    1995a). Such questions need to be addressed

    if progress is to be made in operationalising

    ethnographically derived models of social

    relations.

    Hunter-gatherer archaeology in southern Africa: Mitchell

    2.3 Beyond seasonality? Excavation and stable

    isotope research in the western and southern Cape

    One area of southern Africa with a database rich

    enough to investigate some of these questions is

    the Fynbos and Forest Biomes of the Western and

    Eastern Cape Provinces. Sustained LSA research

    here is almost a century old and provides some of

    the best evidence for social and economic

    intensification during the late Holocene (eg, HJ

    Deacon 1976; Leslie 1989; Hall 1990). With the

    exception, however, of Binnemans (1997a, 1998,

    1999) work in the Baviaanskloof/Kouga region, the

    eastern part of this region has taken a back seat

    in recent years. Along with further documentation

    of plant food collection strategies, one important

    inference drawn here from spatial patterning in

    assemblage variability is that LSA people used

    stone raw materials and the artefacts made from

    them to signal social identities (Binneman 1996a

    and cf Inskeep 1987; Leslie 1989; Hall 1990). The

    context for this, and for the appearance of growing

    numbers of burials, including specialist cemetery

    sites (Hall & Binneman 1987; Hall 2000), was

    probably the desire to assert ownership claims

    within a more crowded landscape that increasingly

    constrained mobility. Storage and intensified use

    of small package resources, such as fish, shellfish

    and plant foods, were other responses (Hall 1988,

    1990, 2000). Stable isotope analyses of human

    skeletons add to this picture. Results from sites

    within the Forest Biome show quite different mixes

    of marine and terrestrial foods over distances of

    less than 20 km. Along with greater diversity in

    body size and an overall decline in mean body size

    after 3300 BP, perhaps because of poorer nutrition,

    this speaks to differentiating lifeways as people

    settled into increasingly smaller territories (Sealy

    & Pfeiffer 2000).

    Broadly similar patterns of change can be

    detected in Parkingtons research area in the

    southwestern Cape. Here one of the past decades

    most striking discoveries has been the realisation

    that the whole area was not abandoned during the

    middle Holocene (pace Parkington et al 1987).

    While remaining true of Elands Bay itself, perhaps

    because of the impact of the mid-Holocene sea

    transgression on coastal and estuarine productivity

    (D Miller et al 1993), excavations a little further

    north at Steenbokfontein Cave (figure 9) show that

    people were still present (Jerardino & Yates 1996).

    Reanalysis of the Tortoise Cave sequence also

    suggests that the many undated artefact

    occurrences in deflation hollows inland of the coast

    are at least 3600 years old (Jerardino 1996 pace

    Parkington et al 1987).

    Figure 9 Steenbokfontein Cave, Western Cape Province, South Africa

    Indeed, they may be several centuries older

    (Manhire 1993) and were perhaps base camps from

    which the coast was visited (Manhire 1987). More

    localised patterns of lithic raw material use and

    intensified exploitation of shellfish, tortoises and

    small bovids are evident after 3500 BP (Jerardino

    1996). Increased rainfall and cooler seas from 3000

    years ago then greatly improved productivity of both

    terrestrial and marine resources (Jerardino 1995b).

    People took advantage of this to base themselves

    almost wholly along the coast, producing huge

    megamiddens almost entirely made up of black

    mussel (Choromytilus meridionalis) shell. Though

    only investigated on a minute scale, these middens

    were certainly more than just shellfish

    accumulations. New excavations demonstrate that

    a range of subsistence and tool-working activities

    took place at them (Jerardino & Yates 1997) and

    they were probably associated with base camps

    located on their edges or at nearby rock-shelters,

    such as Panchos Kitchen Midden (Jerardino 1996,

    1998). However, no sites are known more than 30

    km from the sea anywhere in the southwestern

    Hunter-gatherer archaeology in southern Africa: Mitchell

    Cape at this time and Steenbokfontein is the only

    cave site with any substantial occupation. Its

    central position and large size suggest that it was

    an aggregation focus for an otherwise dispersed

    coastal population, while its deposits may

    ultimately prove to reach back into the Pleistocene

    (Jerardino 1996). They have already yielded the

    oldest confirmed evidence for parietal art in southern

    Africa (Jerardino & Swanepoel 1999), as well as

    important new information on the hafting of stone

    artefacts (Jerardino 2001).

    Once again stable isotope analyses provide a

    complementary perspective on peoples activities.

    Marked differences in isotope composition between

    inland and coastal skeletons suggest corresponding

    differences in diet and landscape use, but it remains

    uncertain whether the technique is emphasising

    protein (from marine animals) at the expense of

    carbohydrates (from terrestrial plants; Parkington

    1991 cf Sealy & Van der Merwe 1992). A wholly

    marine diet has been thought unlikely because of

    possible protein poisoning (Noli & Avery 1988) and

    studies of bone apatite confirm consumption of both

    terrestrial and marine fats/carbohydrates (Lee

    Thorp et al 1989). Experiments and archaeological

    evidence also indicate that people could have

    chosen to store seal and whale meat and blubber

    (A Smith et al 1992; Jerardino & Parkington 1993)

    in order to stay on the coast longer; drying mussel

    meat is another possibility (Henshilwood et al

    1994). The Matopo Hills of Zimbabwe is another

    area where food storage is evident in the middle

    and later Holocene, notably of marula (Sclerocarya

    birrea), which, along with other fruiting trees, was

    a major plant food staple (Walker 1995a). In both

    these areas, in the southern parts of the Cape Fold

    Mountain Belt and perhaps also in KwaZulu-Natals

    Thukela Basin (Mazel 1989), what we may be

    witnessing is the development of more sedentary,

    delayed returns economies (sensu Woodburn

    1982). Whether such economies could have

    provided the basis for an indigenous development

    of food-production, either in the Cape or elsewhere

    in southern Africa, may be doubted. Few, if any,

    African ungulates seem susceptible to

    domestication (Estes 1991; Diamond 1997), while

    key plant food staples typically have long

    maturation times, high processing costs and/or low

    productivities, except where fire-managed (HJ

    Deacon 1995; Parkington 1999). Instead, resources

    for food-production in southern Africa were

    introduced from further north and it is their relations

    with pastoralists and farmers that have become

    another major research focus for archaeologists.

    2.4 Hunter-gatherers and food-producers

    For the past two millennia or so hunter-gatherers

    have shared southern Africa with herders, farmers

    and, more recently, settlers of European origin.

    Though often treated apart, relations between

    hunter-gatherers on the one hand and farmers or

    pastoralists on the other share several concerns:

    changes in landscape use and forager social

    relations; the degree to which foragers took up food-

    production themselves or were assimilated into

    food-producing societies; exchange; and, at the

    most basic level, how we can correctly identify

    livelihood and ethnicity in the archaeological record.

    These questions have been played out over the

    past decade or so in three principal arenas, the

    Kalahari, the southwestern Cape and the Thukela

    Basin, but they are relevant to much, if not all, of

    the sub-continent.

    In the first of these areas, the Kalahari, a

    frequently heated debate has contested the degree

    to which recent forager groups are pristine, or

    instead occupy a marginalised, oppressed position

    on the geographical and social periphery of more

    dominant societies (Wilmsen 1989; Wilmsen &

    Denbow 1990). It now seems likely that many,

    perhaps all, Kalahari Bushmen have had contacts

    with food-producers over the past 2000 years

    (Solway & Lee 1990), but it is not at all clear that

    this necessarily led to their subordination: the

    survival of distinctive and varied hunter-gatherer

    languages, kinship systems, cosmologies and

    social systems that emphasise sharing, reciprocity

    and relatively egalitarian gender relations all

    suggests the contrary (Barnard 1992; Kent 1992;

    Guenther 1996). In the Tsodilo Hills, northwestern

    Botswana, rare finds of iron beads and ceramics

  • 12 Before Farming 2002/1 (3)

    Hunter-gatherer archaeology in southern Africa: Mitchell

    of apparent Iron Age type at White Paintings Shelter

    (Murphy et al 2001), increased evidence of

    hidescraping in first millennium AD LSA levels there

    and at Depression Cave, and the massive extraction

    nearby of specularite and mica (for cosmetics;

    Robbins et al 1993) may all reflect production for

    exchange with farmers. Stone tools and enhanced

    wild game frequencies at the nearby Early Iron Age

    farming village of Nqoma could equally imply

    exchange with, or even settlement of, foragers

    (Denbow 1999). But the empirical basis for any

    more widespread incorporation of foragers into a

    farmer-dominated political economy is weak. As

    Sadr (1998a) shows, the absolute numbers of

    potsherds and metal items in LSA contexts are

    exceptionally low, and bones of domestic livestock

    even fewer, while farmers could certainly hunt

    (Turner 1987) and, as at Bosutswe, make stone

    tools (Denbow 1999).

    Similar issues arise at the opposite corner of

    the Kalahari in the Shashe-Limpopo Basin where

    southern Africas first state society developed at

    Mapungubwe (Huffman 1996; Meyer 1998). The first

    and early second millennia AD saw marked

    increases in forager visibility across the Limpopo

    Valley and Zimbabwes lowveld, and the many

    scrapers at sites like Dombozanga (Cooke &

    Simons 1969) may again reflect intensive skin

    preparation, with iron a valued item obtained in

    exchange (Walker & Thorp 1997). Ivory, a principal

    export to the Indian Ocean coast, may also have

    been supplied by foragers, but whether the many

    bone points from Mapungubwe (Meyer 1998), or

    the stone tools from broadly contemporary Toutswe

    sites further west (Denbow 1999), necessarily

    indicate a forager presence, trade with hunter-

    gatherers, ethnically and technologically mixed

    communities or the use of stone and bone by

    poorer, iron-deficient farming communities is not

    clear. Recent work by Hall & Smith (2000) provides

    a more nuanced appreciation of these problems.

    They argue, from a combination of excavated and

    rock art evidence, that Limpopo Valley/

    Soutpansberg foragers were progressively

    marginalised, first by incoming herders and then

    by farmers. Initially more equitable exchange links,

    which saw hunter-gatherers producing (or working)

    skins, ostrich eggshell and Achatina shell2 for

    nearby farmers, were replaced after AD 1000 by a

    much less egalitarian pattern, linked to the

    establishment of a class structure within the

    emerging Mapungubwe state. A key moment came

    when farmers took over the use of rock-shelters

    from foragers, appropriating the location, and

    sometimes the content, of their art. Though

    ethnohistoric data (Van der Ryst 1998) demonstrate

    the continued presence of foragers into the early

    twentieth century, they seem to have so

    substantially changed their settlement pattern and/

    or material culture that, on present evidence, they

    are archaeologically invisible, and a challenge for

    future research (Hall & Smith 2000).

    Assuming that particular kinds of artefacts

    or sites - in this case stone tools, bone points,

    ostrich eggshell beads and rock-shelters rather

    than open-air villages - carry implications for the

    ethnicity of their creators and users is evident

    not only in the Kalahari, but also in the Thukela

    Basin. While some of the archaeological record

    in southeastern southern Africa undoubtedly

    does speak to exchange relations between

    Early Iron Age farmers and foragers (Mazel

    1989, 1993), stone artefacts could easily have

    been made by farmers themselves, especially

    where iron was difficult to produce as may have

    been the case in the Eastern Cape (Prins &

    Grainger 1993; Binneman 1996b). Genetics

    (Jenkins 1982), linguistics (Anders 1937),

    physical anthropology (A Morris 1993) and

    similarities in divination practices (Hammond-

    Tooke 1998) and rainmaking beliefs (Schapera

    1971; Ouzman 1995; Walker 1997) a l l

    demonstrate the intermarriage of Khoisan

    indigenes with Bantu-speaking, negroid farmers.

    But when such assimilation took place, at what

    rate and under what circumstances remains

    unclear. In some areas, such as the Matopo

    Hills, assimilation may have been rapid (Walker

    1995a), though the scarcity of LSA sites

    elsewhere in Zimbabwe makes it difficult to

    generalise. Further south, hints of change are

    easier to come by, for example the possibility

  • Before Farming 2002/1 (3) 13

    Hunter-gatherer archaeology in southern Africa: Mitchell

    that hunter-gatherers acquired the technology

    to make pottery from a farming (or pastoralist

    ?) source (Mazel 1992), and the possibility that

    those living in the Drakensberg/Maloti Mountains

    reoriented their exchange ties to the west after

    the introduction of farming to KwaZulu-Natals

    lowlands in the early centuries AD (Mitchell

    1996). But only rarely are data sufficiently close

    in time and space to offer more detailed

    interpretations. One area where this may be

    possible is the Magaliesberg Range northwest

    of Johannesburg. Here Wadley (1996b) argues

    that the Ear ly I ron Age set t lement at

    Broederstroom increasingly became an

    aggregation centre for local hunter-gatherers,

    providing a context for intermarriage and

    assimilation. As farming populations expanded

    and overgrazing made hunting and gathering

    more difficult (cf DM Avery 1987) contact

    between forager groups may have been

    hindered, contr ibut ing to a slow social

    strangulation and further assimilation.

    Research in the Caledon Valley shows a

    similar pattern. Though settlement by Iron Age

    farmers only began in the seventeenth century

    AD, foragers were quickly displaced, with the

    primary focus of occupation shifting to smaller

    shelters (Wadley 1995). In the central part of

    the valley rock art rich in trance imagery may

    have helped substitute for the real coming

    together of a now more dispersed population

    (Wadley & McLaren 1998), while changes in the

    ceramics found on LSA sites suggest an

    increasing focus of exchange ties on local farmers

    rather than earlier, more distant connections to

    farmers in KwaZulu-Natal and hunter-gatherers in

    the Karoo and southern Free State (Thorp 2000).

    The southern end of the Caledon Valley, however,

    remained beyond the limit of farming settlement,

    the frontier neatly traced by the negative

    correlation between stonewalled Sotho-Tswana

    villages and rock-paintings that frequently include

    sheep, cattle and Sotho shields, all items

    probably selected as symbols of supernatural

    potency by hunter-gatherer artists (figure 10;

    Loubser & Laurens 1994; Thorp 2000).

    Figure 10 Paintings of cattle, Tienfontein, Free State, South Africa

    Here the ability to survive in areas beyond the

    margins of successful farming allowed some

    foragers to acquire domestic livestock of their own

    and perhaps develop more hierarchical leadership

    structures, a process most clearly seen in the Type

    R stone-walled sites of the Riet River Valley

    (Humphreys 1988). Stable isotope analyses (Lee

    Thorp et al 1993) support Burchells (1967)

    description of a mixed subsistence strategy that

    included both herding and hunting, but excluded

    cultivated cereals.

    Across the western third of southern Africa food-

    production prior to European settlement took the

    form of herding cattle, sheep and sometimes goats

    within an otherwise hunting and gathering economy.

    Historically associated with the Khoekhoen, whose

    descendants survive today in both South Africa and

    Namibia, the archaeology of pastoralism has

    received considerable impetus during the past ten

    years. Substantial projects have been published

    for both Namibia (Kinahan 1991) and the

    southwestern Cape (eg, A Smith et al 1991; Sadr

    & Smith 1991; Smith 1992) and important new work

    is currently being undertaken in the latter region at

    the key site of Kasteelberg (figure 11; K Sadr, pers

    comm). Looked at from a hunter-gatherer

    perspective, key questions remain how livestock-

    keeping was introduced across this region and

    what the relationships were between people with

    livestock and those without. Work by Andy Smith

    and his colleagues in the Vredenburg/Saldanha

    area lies at the heart of much of this discussion.

    They argue that pastoralist and hunter-gatherer

    sites are readily distinguishable in stone tool

    assemblages, ceramic densities, ostrich eggshell

  • 14 Before Farming 2002/1 (3)

    bead sizes and associated faunas (table 2; A Smith

    et al 1991; Yates & Smith 1993). Comparable

    distinctions in settlement signature, rock art,

    l i th ics and ceramics have been drawn

    between Doornfontein (herder) and Swartkops

    (forager) assemblages in the Northern Cape

    (Beaumont et al 1995).

    Figure 11 Kasteelberg Site B (marked by the white bags), Western

    Cape Province, South Africa

    Critiques of these models point to the

    importance of considering variability in what people

    with stock and those without would have done at

    individual sites (Schrire & Deacon 1989; Schrire

    1992). Certainly, attempts to apply these criteria

    elsewhere, as at Die Kelders (Wilson 1996) and

    Jakkalsberg (Webley 1997), are not always

    straightforward. Alternative readings of the

    ethnohistoric literature (Elphick 1985) that envisage

    people moving between high and low points of

    stock-holding within a single socio-economic

    system cannot therefore be wholly excluded, and

    at least some Kalahari foragers have acquired goats

    without (as yet) provoking major social or

    ideological change (Ikeya 1993). Ultimately, this

    debate turns on whether one sees pastoralism as

    having spread through the southwestward

    movement of people (the historic Khoekhoen ?) or

    of animals alone (presumably via exchange links

    and the transformation of indigenous forager

    groups; cf Kinahan [1991] and A Smith et al [1996]).

    As Sadr (1998b) points out, neither position can

    be unequivocally supported at present and

    allowance must be made for the internal evolution

    of livestock-keeping societies (eg, the apparently

    later introduction of cattle into the southwestern

    Cape; Klein & Cruz-Uribe 1989). Nevertheless, the

    development of delayed returns economies by

    megamidden producers in the southwestern Cape

    and subsequent changes in group organisation and

    settlement pattern to cope with deteriorating

    environmental conditions (Jerardino 1996) could

    have made sheep, and the pottery that was

    introduced at broadly the same time, attractive

    innovations. Comparisons with the perhaps similar

    spread of ovicaprines and ceramics in the early

    Neolithic of the Western Mediterranean (Lewthwaite

    1986; Barnett 1995) remain to be explored.

    However introduced, the southwestern Cape

    remains perhaps the easiest area in which to trace

    the impact of herding. Building on earlier work

    (Parkington et al 1986; Parkington & Hall 1987),

    current syntheses see foragers being increasingly

    forced into more marginal parts of the landscape,

    such as the mountains and the drier Elands Bay/

    Lamberts Bay area, as herder numbers grew and

    livestock competed with wild game on higher nutrient

    soils. Stable isotope studies indicate reworkings

    of the integration of marine and terrestrial foods

    (Sealy & van der Merwe 1988; Lee Thorp et al 1989),

    while the earlier fine-line painting tradition gradually

    disappeared, as suggested by the complete

    absence of cattle imagery and low incidence of

    sheep paintings (Yates et al 1994). That the latter

    are almost wholly lacking near the coast (Manhire

    et al 1986; but cf Jerardino 1999) implies that fine-

    line paintings ended there first, where the

    introduction of livestock had the greatest impact.

    Work in the Seacow Valley on the eastern edge

    of the Karoo has also contributed much to our

    understanding of herder-forager relations. Here

    analyses of temper, clay, size and shape

    differentiate quartz-tempered Khoekhoe pottery from

    grass fibre-tempered, stamp-impressed hunter-

    gatherer wares (Bollong et al 1997; Sampson &

    Sadr 1999). Stratigraphic evidence and direct dating

    of sherds suggest that both kinds of ceramics were

    introduced around the same time, with foragers

    perhaps taking up pot-making technology from

    incoming herders. Though the grass-tempered

    wares can be sequenced stylistically (Bollong et

    al 1993; Sampson & Vogel 1995; Bollong &

    Sampson 1996; Sampson et al 1997), their variety

    and the large areas over which people clearly moved

    have precluded successful analyses of the social

    geography of their makers (cf Sampson 1988).

    However, applying close vertical and horizontal

    controls during excavations of rock-shelters that

    have only poorly developed stratigraphies shows

    that forager population levels closely tracked

    climatic change (Sampson et al 1989; Bousman

    1991; Sampson & Plug 1993). In particular, ostrich

    egg collection seems to have intensified greatly

    after 400 BP as a partial substitute for declining

    game numbers during the Little Ice Age (Sampson

    1994); herding and a local Khoekhoe presence may

    have disappeared from the upper Seacow Valley

    at this time as both went unreported by later

    European settlers (Sampson 1996).

    The Seacow Valley, scene now of some two

    decades of research by Garth Sampson and his

    colleagues, is also an area where archaeology has

    successfully tracked the impact of European

    settlement on southern Africas hunter-gatherer

    peoples. Lying on the northeastern edge of late

    eighteenth century colonial settlement, the Swy i

    Bushmen strongly resisted European expansion,

    forcing farms to cluster together for protection

    (Sampson et al 1994). Only after 1800 did the

    combination of gifts, genocide and the destruction

    of game herds succeed in subjugating them.

    Survivors had few options but to become farm

    labourers, acquiring domestic stock and access

    to a range of European cultigens, beads, ceramics

    and other goods (Saitowitz & Sampson 1992;

    Sampson 1993, 1995; Sampson & Plug 1993);

    sites in the Caledon Valley may record a similar

    story (Wadley 1992b; Thorp 1997). To the northwest

    Janette Deacon (1996b) has identified several

    nineteenth century /Xam Bushmen sites mentioned

    by people who worked with Lucy Lloyd and Wilhelm

    Bleek in the late 1800s, but visible connections

    with the colonial economy are much fewer.

    Elsewhere, rock art remains an important source

    of evidence for how hunter-gatherers coped with

    European expansion. In the Drakensberg/Maloti

    Mountains Dowson (1994, 1999) has elaborated

    on the model first developed by Colin Campbell

    (1987), who argued that shamans rose to positions

    of leadership and dominance by capitalising on their

    abilities to protect their communities, make rain

    for farmers and co-ordinate raids and trade. Though

    more intense, accelerated and ultimately much

    more destructive, the assimilation and

    displacement provoked by European settlement

    may not have been wholly dissimilar to earlier

    impacts by pastoralists and farmers.

    3 Future directions

    The local development of archaeology as a

    discipline was one consequence of European

    settlement in southern Africa, producing

    understandings of the past often at variance with

    those of indigenous peoples. In turning briefly to

  • 16 Before Farming 2002/1 (3)

    Hunter-gatherer archaeology in southern Africa: Mitchell

    what the future may hold for hunter-gatherer

    archaeology in the sub-continent this seems an

    appropriate starting point. Across southern Africa

    indigenous people are increasingly taking an

    interest in their past. The highlighting of Khoisan

    descent by groups within the Western Cape has,

    for example, precipitated calls for the reburial of all

    human skeletons in existing museum collections

    (Jordan 1999), and may make their further

    excavation difficult. The Southern African

    Association of Archaeologists has adopted a clear

    code of ethics as a pro-active response to such

    concerns, and some skeletons have already been

    reburied after analysis (Sealy et al 2000). Other

    responses include opportunities for archaeological

    training of Ju/hoan people in northern Namibia (A

    Smith & Lee 1997; Lee & Hitchcock 1998), and

    the development of community-based approaches

    to the presentation and conservation of

    archaeological resources (eg, Clanwilliam Living

    Landscape Project 2001). Both conferences, such

    as the 1997 Cape Town-based Khoisan Identities

    and Cultural Heritage Conference, and specific

    events, like the reopening of the Tandjesberg

    National Monument rock art site in the eastern Free

    State (D Morris et al 2001), seek to include people

    of Bushman descent, while major exhibitions have

    expanded awareness of the cultural richness and

    mistreatment of hunter-gatherer communities (eg,

    Skotnes 1996).

    One area where the involvement of forager

    communities and their descendants may become

    particularly important is the archaeological

    investigation of the prehistory of known Khoisan

    groups. As Walker (1995b) points out, despite the

    frequency with which they are invoked by

    archaeologists, very little is known about the

    antecedents of twentieth century Kalahari

    Bushman peoples. Work by Larry Robbins and his

    colleagues in northwestern Botswana should pay

    dividends here and already attests to the antiquity

    of mongongo nut (Ricinodendron rautanenii)

    exploitation, freshwater fishing and a sophisticated

    worked bone technology, as well as to important

    changes in regional climate (Murphy 1999; Robbins

    et al 1994, 1996a, 1996b, 1998; Robbins & Murphy

    1998). Their research is also helping to fill one of

    the many outstanding gaps on the map of hunter-

    gatherer archaeology in southern Africa. Others

    include virtually all of Zimbabwe, outside of the

    comparatively well-studied area of the Matopo Hills

    (Walker 1995a; Walker & Thorp 1997); much of

    Namibia, though here work by Vogelsang (1998,

    2000) in Kaokoland is now complementing earlier

    foci in the Brandberg and central Namib; and the

    savanna regions of the former Transvaal, where

    research in the Shashe-Limpopo Basin (Eastwood

    & Blundell 1999; Hall & Smith 2000) and the

    Waterberg Plateau (Van der Ryst 1998) continues

    to stand almost alone. One important question in

    all of these regions, and elsewhere in southern

    Africa, will be determining the extent to which

    apparent breaks in regional settlement histories

    are real or the product of archaeological research

    strategies. In the former Transvaal, for example,

    does the continuing dearth of early/middle Holocene

    LSA occupation reflect reality, or a preference for

    hard-to-find-and-date open-air sites, such as those

    at Honingklip (Korsman & Plug 1994)?

    Linked to this issue is the extent to which

    variation in the availability of major plant food staples

    can explain patterns of regional settlement (HJ

    Deacon 1993). Connections between spatio-temporal

    patterning in the distribution of archaeological sites,

    viewed as proxy evidence for the density and

    distribution of people, and environmental change have

    been a longstanding concern for southern African

    archaeologists (HJ Deacon & Thackeray 1984). But

    we are still far from being able to translate

    broadbrush impressionistic statements about

    precipitation and temperature into meaningful

    quantitative data, let alone impacts on the

    productivity of the plant and animal resources that

    people used (but cf JF Thackeray 1988). Master

    sequences of palaeoenvironmental change are

    slowly being developed, notably from the Tswaing

    Crater (Partridge 1999) and Cold Air Cave (Lee Thorp

    & Talma 2000). Smaller scale phenomena, such as

    the Younger Dryas stadial, are also being recognised

    (JF Thackeray 1990; Cohen et al 1992; DM Avery

    2000), but there is a long way to go in building up a

    detailed picture for the whole sub-continent, even

  • Before Farming 2002/1 (3) 17

    Hunter-gatherer archaeology in southern Africa: Mitchell

    for the period since the Last Glacial Maximum.

    Dating is another area where much progress has

    been made. Many thousand radiocarbon

    determinations are now available and, as indicated

    earlier, several new techniques are being applied to

    the chronology of the Middle Stone Age. This is,

    perhaps, the most crucial area for which dating must

    be improved, not least because of radiocarbons

    inapplicability much before c 40,000 BP, the rarity of

    long sequence sites and the vagueness with which

    spatial and temporal variability in MSA industries is

    still defined. In particular, the coherence of the

    Howiesons Poort as a single entity (Parkington 1990),

    the behavioural significance of industrial variability as

    indicating the deliberate investment of material culture

    with stylistic messaging (Wurz 1999; dErrico et al

    2001) and the archaeology of almost the entire sub-

    continent during Oxygen Isotope Stage 3 (Mitchell in

    press) all demand much more research. But Later

    Stone Age dating frameworks too need to be

    addressed, since calibration is generally only applied

    to dates of the last two millennia or so. Only when

    this has been systematically undertaken shall we be

    able to compare rates of cultural and environmental

    change in a meaningful fashion. On a final

    chronological note: while dating of rock paintings and

    engravings has been the subject of important recent

    advances, particularly accelerator radiocarbon dating

    (Mazel & Watchman 1997) and the sophisticated

    application of Harris matrices (Russell 2000), much

    more is required for rock art (figure 12) to be integrated

    into the rest of the archaeological record.

    Figure 12 Paintings of human and antelope figures, Giants Castle,

    KwaZulu-Natal, South Africa

    Dismissing such concerns as chronocentric

    is not enough. Unless rock ar t can be

    contextualised in time, as well as in space,

    instead of speaking to the social and ideological

    relations of past hunter-gatherer societies,

    interpretations that employ it run the risk of

    producing unvarying, ahistorical and synchronic

    understandings of the whole archaeological

    record (Parkington 1998).

    The same danger haunts other uses of

    ethnographic data in southern Africa, and not

    just archaeological studies of hunter-gatherers

    (cf Lane 1994/95; Beach et a l 1997).

    Archaeologists continue to concentrate on Ju/

    hoansi, G/wi and /Xam Bushmen as role models

    for LSA peoples, despite the great diversity

    among surviving Bushman groups (Barnard

    1992) and the still greater linguistic, and likely

    cultural , var iat ion among now ext inct

    communities south of the Limpopo River (Traill

    1996). And this is before one considers changes

    over time in the histories of the peoples

    concerned, something emphasised by the

    Kalahari debate. The time is long overdue to de-

    !Kung the Later Stone Age (Parkington 1984) and

    to investigate southern African prehistory using

    a much broader set of anthropological and

    archaeological parallels, including those from

    other parts of the world and from groups practising

    delayed returns economies (Hall 1990). The

    increasing involvement of overseas researchers

    in the study of southern Africas past, especially

    the appearance of anatomical ly modern

    humans, should promote this trend (table 3),

    though the closure or restructuring of university

    departments and chronic underfunding of

    museums in South Africa is a cause of concern

    (Binneman 1997b). Working with and alongside

    local scholars and indigenous communities, the

    result should be to make concrete the motto of

    South Africas new coat of arms (!ke e: /xarra /

    /ke - People who are different join together),

    collectively expanding our knowledge of the

    hunter-gatherer peoples from among whom it is

    taken (B Smith et al 2000).

    Hunter-gatherer archaeology in southern Africa: Mitchell

    1 Southern African archaeology, anthropology and history constitute a minefield of potentially offensive terms. The problem is that the vocabularies

    of the indigenous hunter-gatherer and herder groups of southern Africa traditionally lacked inclusive names for themselves larger than those of the

    linguistic unit to which they belonged. Bushman first appears in written form in the late seventeenth century and came to be employed by

    Europeans as a generic term for people subsisting primarily from wild resources. However, it also acquired derogatory, pejorative (and, indeed,

    sexist) overtones, with the result that it began to be replaced in academic writings from the 1960s with the supposedly more neutral and indigenous

    term San, a Nama word for their hunter-gatherer neighbours. Unfortunately, since this literally means foragers, implying that those concerned are

    people of lower status too poor to own livestock, it too is not without problems, one of which is that many forager groups actually speak languages

    identical or closely related to those of southern Africas indigenous herders! Another solution is offered by the Botswanan governments change of the

    Tswana term Sarwa (Bushman) to BaSarwa, the Ba prefix placing it in the same class of nouns as people speaking Tswana and its closest relatives

    (Wilmsen 1989); the Sotho term Baroa shows a similar predisposition. Perhaps to avoid the problems inherent in both Bushman and San some

    archaeologists now employ Basarwa when describing Later Stone Age hunter-gatherers outside the confines of modern Botswana (eg, Bollong et al 1993).

    Clearly, none of these terms is ideal and people of hunter-gatherer origin in the Kalahari express different preferences. While Namibias Ju/hoansi

    choose Bushmen over San, some Botswanan groups use Basarwa, though San and Khoe also have their indigenous advocates (Lee &

    Hitchcock 1998). In this confused situation I use the term Bushman, rejecting any derogatory connotations that it may have and agreeing with

    Barnard (1992), who sees no reason to employ a Tswana or Nama, rather than an English, word in an international context. I follow him too in spelling

    the names of individual Bushman groups, but use Ju/hoansi, their own name for themselves, for the people commonly referred to in the literature

    as the !Kung, a more all-embracing, linguistic term (after Biesele 1993).
