Question

Quizplus · Accepted Answer

Speciation is the process of the formation of new species, and it is an essential process for understanding macroevolution, the diversification of life on Earth over long periods. Options A, B, C, and D are incorrect because natural selection does not have the goal of speciation; two allopatric populations will not interbreed freely if speciation has occurred; natural selection does not choose reproductive barriers for populations; and postzygotic reproductive barriers usually evolve before prezygotic barriers.
