1. Taxonomy
(Naming and Grouping)

2. Why is a naming system important?
Have you seen a…
Florida panther?
Cougar?
Mountain lion?
Catamount?
Puma?
They are all the SAME animal!
Their difference is their regional “common name”

3. The origins of taxonomy
Taxonomy → grouping and naming of organisms
to understand the variety of life
to avoid confusion of regional names
Carl (Carolus) Linnaeus ( )
developed a binomial nomenclature (2-part name), now called the scientific name
developed a 7-level (taxon) classification
(domain), kingdom, phylum, class, order, family, genus, species

4. The Three Domains (added in 1990) (…eukaryotes)
(…”common” prokaryotes)
(…“ancient” prokaryotes)

5. The scientific name is taken from the genus and species

6. Members of a genus share more in common than members of a family
Taxonomic groups
Beginning with domain, each successive level of classification becomes more specific
Organisms within the same group have more in common with one another than those within the next largest group
Members of a genus share more in common than members of a family

7. Kingdoms and Domains The Three Domains The Six Kingdoms Archaea
Bacteria
Eukarya
The Six Kingdoms

8. What is a Cladogram?
Cladogram → diagram that shows evolutionary relationships between organisms
Helps scientists understand how one lineage broke away from another in the course of evolution

9. What is a Dichotomous Key?
Dichotomous key → classification used to identify unknown organisms
Based on visible similarities
