1. Classification

2. Classification
The arrangement of organisms into orderly groups based on their similarities

3. Taxonomy The study of classification and organization of life forms
Carolus Linnaeus - today

4. Why Classify? Many different species Easier for scientists
How many species?
Characteristics?
Relationships between species?

5. Levels of Classification
Kingdom
Phylum
Class
Order
Family
Genus
Species

6. Mnemonic Device
King Philip Came Over for Grape Soda

7. Taxonomy
Kingdom – wide variety
Species – very specific

8. Species Specific scientific name Genus (Capitalized)
Underline or Italicize
Genus (Capitalized)
Specific epithet (lower case)
Example
Human – Homo sapiens
Cat – Felis domestica

9. Naming Species Latin or Greek origins Meanings describe the organism
Example: Tyrannosaurus rex
Tyranno – tyrant
Saurus – lizard
Rex - king

10. Why Scientific Names are Important. . .
Many common names = 1 species
Example = rabbit
Bunny
Cottontail
Hares
Scientific name = Oryctolagus cuniculus

11. Cladograms & Dichotomous Keys

13. Cladistics is classification based on common ancestry.
Phylogeny is the evolutionary history for a group of species.
evidence from living species, fossil record, and molecular data
shown with branching tree diagrams

15. Convert the Venn Diagram into a Cladogram
Lizard
Trout
Human
Earthworm
Hair
Legs
Vertebrae

16. Using Observable Characteristics to Identify Objects
Dichotomous Key
