Question

Quizplus · Accepted Answer

The process described in the question, where the average beak size in a population of birds may change between successive generations in response to environmental conditions, is an example of microevolution. Microevolution refers to small-scale changes that occur within a population over a relatively short period of time, such as changes in allele frequencies or physical traits. Choices A, C, and D all refer to larger-scale evolutionary processes that occur over longer periods of time and involve more significant changes in populations or species. Choice B is not a relevant term in this context.
