2. What is Taxonomy? Taxonomy naming organisms based on common
traits Scientists name large groups of animals, smaller groups, all
the way down to individual species. The system they use to name
animals is this: Domain Kingdom Larger groups PhylumTaxonomic
Groups Class Order Order Family Family Genus Species Species

4. Example: Humpback WhaleWikipedia gaveme the Kingdom,Phylum,
Class,Order, Family,Genus andSpecies
5. Species Scientific NamesSpecies names are always binomials,
which means there are 2 names,example:Carcharodon carcharias is the
scientific name for a great white shark.Scientific names are
derived from Latin.Kingdom, phylum, class, order, family, genus are
NOT binomials.Carcharodon carcharias
6. Taxonomy and Trees Organisms are named based on their
position on evolutionary
trees.KingdomPhylumClassOrderFamilyGenusSpecies
7. How Trees are ConstructedToday, most trees are constructed
using DNA. Single basepair differences in the DNA are
traits.Extinct species are put onto the trees using traits from
theorganisms fossils.
8. Scientific vs Common Names Animals have scientific and
common names. Common names example: catfish But there are about
3000 species of catfish!! So which one?? Scientific names example:
Lacantunia enigmatica Lacantunia enigmatica is ONE species of
catfish, so scientists from different countries can talk about it
without any confusion. Scientific names are more clear and lead to
less confusion Good bad examplesCommon name Easy to remember Some
species can Large forest gecko have many Catfish common
namesScientific name -One species will have Hard to Gekko smithii
only one scientific name. remember and Lacantunia enigmatica -Clear
for people who pronounce speak different languages.

10. Questions1. Why might using a scientific name be better
than a common name?2. Name the 8 major taxonomic groups that
scientists put organisms into.3. What taxonomic group is Sceloporus
occidentalis in? Hint: the answer is one of the 8 groups you listed
in number 2.4. Tell me what taxonomy is in your own words.5. What
do scientists use to construct the evolution trees we use today?6.
What is the binomial species name for humans?7. What kingdom are
humans in?
