Reproductive Isolation is KEY!!
Reproductive Isolation: Temporal
Reproductive Isolation: Behavioral
Rana utricularia
(Southern Leopard Frog)
Reproductive Isolation: Mechanical
Adaptive Radiation - evolution of many new species from a
common ancestor introduced to new and diverse environments
Rana catesbiana
(Bullfrog)
Reproductive Isolation: Gamete Incompatibility
Predation and Coevolution
Coevolution - When the populations of two species interact and
changes of the gene pool of one species leads to the change of
the gene pool of the other species.
