2. Classification & Taxonomy
Essential Question: How is the diversity of life classified and named?

3. Who are YOU???

4. What do YOU call this animal?

5. Basic Definitions
Classification
Taxonomy

6. Why classify organisms?
To organize the diversity of life
To help us know what organism we are referring to

7. Who developed our current classification system, and what is it?
Carolus Linneaus

8. Levels of Classification
Family
Genus
Species
Kingdom (6)
Phylum
Order
Class

9. Linnaean System of Classification
Each level is called a taxon
Smallest taxon is the species
Species ~ only level where organisms interbreed

10. Example
grouping together all forms of life having certain fundamental characteristics in common:

11. There are 6 Kingdoms

12. How do we name organisms?
Each organism is given a two-part scientific name using only the Genus and species names
binomial nomenclature

13. Why do we use Scientific Names?
South America – gato monte
North US - puma
South US – mountain lion
Florida - panther
Scientific Name – Felis concolor

14. 3 Rules for writing Scientific Names
1) First letter of genus – ALWAYS CAPATILIZED
2) First letter of species – never capitalized
3) Scientific names are italicized (if typed) or underlined if hand written

15. Examples Ursus maritimus Ursus arctos Genus-Ursus = bear
Species-maritimus = sea
Species-arctos = grizzly

16. Which of these are written correctly?
Viola tricolor (pansy with 3-colored flower)
Quercus phellos (Willow Oak)
Nymphaea ordata (fragrant water lily)
Clostridium Botulinum (bacteria that causes a form of food poisoning)
homo sapiens

17. Which of these are written correctly?
Viola tricolor (pansy with 3-colored flower)
Quercus phellos (Willow Oak)
Nymphaea ordata (fragrant water lily)
Clostridium Botulinum (bacteria that causes a form of food poisoning)
homo sapiens

18. 2 Rules for assigning scientific names
1) All scientific names must be Latin words/terms
2) NO two organisms can have the same scientific name

19. Grizzly bear
Black bear
Giant panda
Red fox
Abert squirrel
Coral snake
Sea star
KINGDOM Animalia
PHYLUM Chordata
CLASS Mammalia
ORDER Carnivora
FAMILY Ursidae
GENUS Ursus
SPECIES Ursus arctos

23. Questions???

24. CONCEPT REVIEW: True or False
1) Biologists use a classification system to name organisms and group them in a logical manner.
TRUE

25. CONCEPT REVIEW: Multiple Choice
The science that specializes in the classification of organisms is
anatomy
taxonomy
botany
biology

26. CONCEPT REVIEW: Multiple Choice
The science that specializes in the classification of organisms is
anatomy
taxonomy
botany
biology

27. CONCEPT REVIEW: Multiple Choice
The largest most inclusive of Linnaeus’s taxonomic categories is the
kingdom
phylum
order
species

28. CONCEPT REVIEW: Multiple Choice
The largest most inclusive of Linnaeus’s taxonomic categories is the
kingdom
phylum
order
species

29. The Tree of Life has been updated since Linnaeus’s time
Scientists now classify organisms into an even broader category, called the domain, above the kingdom level

30. 3 Domains: Archaea, Bacteria & Eukarya
Eubacteria
Archaebacteria
Protista
Plantae
Fungi
Animalia
DOMAIN EUKARYA
DOMAIN ARCHAEA
DOMAIN BACTERIA

31. Identifying organisms using a dichotomous key
a key used to identify an organism
each stage presents descriptions of two distinguishing characters, with a direction to another stage in the key, until the species is identified

34. Classification Today
Diagrams depicting evolutionary relationships based on molecular evidence.
Phylogeny
Cladogram

35. Reading a cladogram/phylogeny
Each branch represents an evolutionary lineage
X-axis is evolutionary distance from each other and the y-axis is relative time
Intersecting lines represent a speciation event
