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

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

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?

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.
