A researcher studying bees, wasps and their harmless mimics notices that there are distinctly different populations found in certain. She postulates that this is due to primarily to coevolutionary relationships that are different in different areas due to the distribution of various models and mimics and their predators. If this hypothesis is correct it would be a clear example of . a ring species abiotic natural selection regional partitioning mosaic coevolution asymmetric genetic drift

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
