phenotypic and genetic similarities due to shared ancestry

• homologies

• analogy

• convergent evolution

ancestral species but not all descendants

• monophyletic

• paraphyletic

• polyphletic

distantly related species but no recent ancestor

• monophyletic

• paraphyletic

• polyphyletic

closely related species but not part of group studied

• ingroup

• outgroup

• maximum parsimony

• molecular clock

fewest # of changes that had to happen most likely happened

• ingroup

• outgroup

• maximum parsimony

• molecular clock

uses constant rate of evolution observed in genes to estimate absolute time of evolutionary changes
