Does sexual reproduction alone necessarily cause evolution?

Question

Quizplus · Accepted Answer

Sexual reproduction creates genetic variation, but whether or not this variation results in evolution depends on whether natural selection, genetic drift, or other factors act on the variation. Therefore, sexual reproduction alone does not necessarily cause evolution. Option A and D are incorrect because genetic drift is a random process that can occur in populations with or without sexual reproduction, and new combinations of alleles produced by sexual reproduction can certainly be subject to natural selection. Option B is incorrect because mutations can occur spontaneously, regardless of whether organisms reproduce sexually or asexually.
