The science of grouping organisms according to their presumed natural relationships.

ARISTOTLE◦ First to classify organisms more than 2000

years ago.◦ Classified all organisms into TWO groups

Plants Further classified by stem differences.

Animals Further classified based on where animals

were found. (air, land, water)

Page 3: Chapter 18. The science of grouping organisms according to their presumed natural relationships. ARISTOTLE ◦ First to classify organisms more than.

Everyday names given to organisms. Common names may NOT accurately

describe the organism.◦ Examples: jellyfish, mountain lion

Mean:Two Names CAROLUS LINNAEUS – Swedish naturalist

(1707-1778)◦ He broke organisms into hierarchical categories

Binomial name Includes Genus

& species names Examples:

◦ Rana pipiens- Leopard frog

◦ Homo sapiens – Human beings

Page 7: Chapter 18. The science of grouping organisms according to their presumed natural relationships. ARISTOTLE ◦ First to classify organisms more than.

Subspecies: morphologically different & geographically separated.

Varieties: Morphologically different & often not geographically separated.

Strain: Biochemically dissimilar group within a species.◦ Example: bacteria

Page 8: Chapter 18. The science of grouping organisms according to their presumed natural relationships. ARISTOTLE ◦ First to classify organisms more than.

Phylogeny: Evolutionary history of a species.

Taxonomic Identification:◦ Dichotomous Key – A written set of choices that

leads to the name of an organism.◦ Phylogenetic Tree – A visual model of the inferred

relationships among organisms.◦ Biosystematics – A form of taxonomy that

examines reproductive compatibility & gene flow. Studies speciation, or formation of a new species.
