1. Phylogenetics: Attempts to show evolutionary relationships among living and once-living organisms Cladogram: Branching tree diagram that hypothesizes common ancestry.

2. This is called a phylogenetic tree!
It shows evolutionary relationships.
Each branch point represents a common ancestor of the species above that point.

5. This is a another PGT…also called a CLADOGRAM
Can you tell which organisms share a common jawed vertebrate ancestor?
Which organisms have a common tetrapod, amniote, and mammal ancestor?

6. Open Response Practice…do it or…well…hypothesize as to what happens you don’t
Red, Blue, & Orange:
Explain the interrelationship among genetics, natural selection (and it’s four mechanisms), and evolution.
Purple & Green:
In terms of natural selection, explain what would happen to a population of small fish living in a pond. Be explain all four mechanisms that we’ve discussed.
