Question

Quizplus · Accepted Answer

Evolution is the change in gene frequencies within a population over generations. This can lead to changes in the phenotypes observed, as certain genetic traits become more or less common in the population. While mutations can introduce new genetic variation, it is the changes in gene frequencies through processes such as natural selection or genetic drift that lead to evolution. The heritability of characteristics is relevant in evolution insofar as it influences the degree to which certain traits are passed from one generation to the next, but it is not the defining factor in evolutionary change.
