1. Classification History

2. Classification History
Taxonomy: Branch of biology that groups all life according to their characteristics and history
All life on earth is placed into 1 of 6 kingdoms:
Eubacteria
Archaea
Protista
Fungi
Plantae
Animalia
Classification
History
prokaryotes
eukaryotes

3. Developed classification system based on physical features
Many rules still used today
Binomial Nomenclature: System of giving every organism 2 names
1st word: Genus (broad)
2nd word: Species (specific)
Example: House cat
Genus: Felis (cougars, lions, tigers, cheetahs, etc…)
Species: catus
Carolus
Linnaeus

4. Binomial Format Bos taurus When Writing: Genus capitalized
species lowercase
Underlined entirely
Ex: Homo sapiens
When Typing:
Same, except use italics
Bos taurus

7. Taxa 7 individual levels (taxa) used to classify organisms
Kingdom (broadest)
Phylum
Class
Order

Allows relationships to be clearly seen

12. The more levels in common...the more related the species.

13. Which two organisms are most related to one another?
Killer Whale K = Animals P = Chordata C = Mammals O = Cetacea F = Delphinidae G = Orcinus S = orca
Red Wolf K = Animals P = Chordata C = Mammals O = Carnivora F = Canidae G = Canis S = vulpes
Polar Bear K = Animals P = Chordata C = Mammals O = Carnivora F = Ursidae G = Ursus S = arctos
