Name, describe, and give specific real-life examples of several of these barriers. Then describe several ways they can evolve. Suppose you are studying a population of an animal or plant. Briefly state several ways by which you could determine if your population is indeed a locally adapted ecotype. Then describe in some detail how this putative ecotype could have evolved to be distinct from neighboring populations.
Prokaryotes often live in rapidly changing environments.
Briefly discuss the advantages of the prokaryotic gene regulation mechanisms in such an environment.
