by considering reproduction and genetics.
Successful hybridization rare in animals; occurs frequently in plants
One species gradually transforms into another through a series of intermediate stages
Brief bursts of rapid evolution interrupting long period of little change
(transitional forms don’t exist—explains lack in fossil record)
Fits w/allopatric speciation – geographic isolationSpeciation—Punctuated equilibrium
populations that diverge
genetically, split off, form
