Question

Quizplus · Accepted Answer

There are physical and genetic constraints that organisms cannot overcome. The environment is constantly changing, making it difficult for natural selection to keep up. Additionally, natural selection lacks foresight and can only work with the variation that currently exists in the population. Therefore, organisms cannot be perfectly adapted to their environment.
