Lecture 16: Comparative Methods: Trees, Maps, and Traits (EEB 122)
This lecture demonstrates how comparative methods, particularly molecular genetics, link phylogenetic information to geographic histories and trait evolution. It highlights human migration patterns and how independent contrasts reveal ancestral trait states.
Principles of Evolution, Ecology and Behavior (EEB 122)
We can use methods of genetic analysis to connect phylogenic information to geographical histories. Human migration has left genetic traces on every continent, and allows us to trace our roots back to Africa. Molecular genetic methods allow us to determine whether or not trait states were ancestral, which can have profound implications for fundamental biological ideas.
