1. Classification

2. Taxonomy-branch of biology that names and groups organisms according to their characteristics and evolutionary history
-Aristotle-Greek philosopher, classified living things as plants or animals; 2,000 years ago
*What would be some problems associated with this type of classification?

3. -Carolus Linnaeus ( ), Swedish naturalist, used an organism's morphology (form and structure) to categorize it

6. Binomial Nomenclature-system of two-part names
-Latin names
-Italicized, genus and species name together=species name
Ex. Homo sapiens
Ex. Terrapene carolina
Ex. Macracanthorhynchus hirudinaceus
phylogeny-evolutionary history of an organism,helps to classify organisms

7. Phylogenetic Tree-family tree that shows evolutionary relationships, subject to change

9. Evidence for the construction of phylogenetic trees:
Fossil Record
Morphology
Embryological Patterns of Development
Chromosomes-karyotypes
Comparing DNA, RNA, and proteins (lab)

10. Cladistics-uses shared derived characters of organisms to establish evolutionary relationships
Ex.-feathers evolved in the bird group

11. Dichotomous Keys-help identify organisms according to their scientific names
