4. Molecular Clocks ► Molecular biologists can use an estimated constant rate of evolution for proteins and DNA to determine the history of lineages. § Still a controversial technique § Calibrated from known fossil record § Tested against other lines of evidence § Can be used as a model for when to search for important fossils.

8. Phylogeography ► Systematics – The study of the evolutionary relationships between organisms ► Monophyletic – A group of organisms that include an ancestral taxon and all of its descendents ► Paraphyletic – A group that includes an ancestral taxon and some but not all of its descendents ► Polyphyletic – A grouping different from above that is an artificial taxon ► Clade – A monophyletic evolutionary branch
