Questiоn 5: True оr Fаlse, Speciаtiоn, 14 points Answer the following questions true or fаlse True or False: Sympatric speciation requires a physical barrier to separate populations. (2 pts) True or False: Hybrid sterility, such as in mules, is an example of a postzygotic reproductive barrier. (2 pts) True or False: Geographic isolation is the only way new animal species can form. (2 pts) True or False: Temporal isolation, such as differences in breeding seasons among closely related frog species, is considered a postzygotic reproductive barrier. (2 pts) True or False: Hybrid zones always lead to the fusion of two populations back into a single species. (2 pts) True or False: Sexual selection, such as female preference for specific male courtship displays in birds, can drive speciation even without geographic isolation. (2 pts) True or False: Adaptive radiation in animals typically occurs when a single ancestral species rapidly diversifies into multiple species in response to unoccupied ecological niches, as seen in cichlid fish in African lakes.
