Question

Quizplus · Accepted Answer

Evolutionary biologists do not necessarily agree about the extent to which the lack of genetic variation constrains the rate and direction of evolution. Some argue that low genetic variation can limit the ability of populations to adapt to changing environments, while others argue that it can lead to the spread of advantageous mutations more quickly. Therefore, statement B is false.
