Question

True or false: Natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.

Answer 1

Based on the genetic variation, it is true that natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.

What is natural selection?

Natural selection is the process by which species which are better adapted to an environment survive over those not suited to the environment.

Does natural selection produce perfect adaptations?

Natural selection do not produce perfect adaptations because:

1. Adaptations are often compromises.
2. Organisms are locked into historical constraints.
3. Selection can only edit variations that exist in a present population.

Therefore, it is true that natural selection does not always produce perfectly working adaptations, because it can only work on the genetic variation present in a population.
