Migration is a key evolution mechanism by which microevolution occurs.

Question

Quizplus · Accepted Answer

Migration leads to the introduction of new genetic variation into a population, which can drive microevolutionary change over time. As individuals migrate from one population to another, they bring with them different alleles and genotypes that can alter the allele frequencies and genetic composition of the recipient population. This can increase genetic diversity, facilitate adaptation to new environments, and promote speciation. Therefore, migration is considered a key mechanism of microevolution.
