1. CLADOGRAMS CHAPTER 18 SECTION 2
THE STUDENT WILL USE A PHYLOGENETIC TREETO IDENTIFY THE EVOLUTIONARY RELATIONSHIPS AMONG DIFFERENT GROUPS OF ORGANISMS

2. Taxonomy
dfn: discipline of classifying organisms & assigning each organism a universally accepted name
taxon: group or level of organization into which organisms are classified
ex: Genus Homo is a taxon in the classification of humans

3. Binomial Nomenclature
each species is assigned a 2 word scientific name:
consists of the Genus & species
Genus name is capitalized
species name is not capitalized
both in italics
Ex: Homo sapiens

4. 3 Domains

5. Classification of Living Things

6. Classification of Living Things
Linneaus’s hiearchical system based on physical similarities
now, organisms grouped into categories that represent lines of evolutionary descent or, phylogeny

7. Phylogeny
evolutionary classification: strategy of grouping organisms together based on their evolutionary history

9. Cladograms Most biologist now use a method called Cladistic Analysis
method uses only those characteristics that are evolutionary innovations
Derived Characters: present in recent parts of a lineage but not in its older members
Use them to construct cladogram
