1. History of Classification

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

5. Taxa 7 individual levels (taxa) used to classify organisms
Kingdom (broadest)
Phylum
Class
Order
Family
Genus
Species (specific)
Allows relationships to be clearly seen

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

12. 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

16. Kobe??? Who Cares!?!?!?!
A patient walks in with an unknown fungal skin disease. You are able to partially classify the new fungus.
K: Fungi
P: Basidiomycota
C: Heterobasidiomycetes
O: Tremellales
F: Filobasidiaceae
G: ?????
S: ?????
You recognize that the fungus is very similar to the infectious fungus known as Malassezia furfur.
K: Fungi
P: Basidiomycota
C: Heterobasidiomycetes
O: Tremellales
F: Filobasidiaceae
G: Malassezia
S: furfur
How can classification help this patient?
Perhaps the Malassezia furfur treatment can be applied to our unknown disease.
