Question

what role does natural selection play in evolution? it only affects extinct species. it drives the adaptation of species to their environment. it selects for traits that are less suitable for the environment.

Explanation:

Natural selection is a key mechanism in evolution. It acts on the variation within a population. Organisms with traits that are better adapted to their environment are more likely to survive and reproduce, passing those advantageous traits to their offspring. Over time, this leads to the adaptation of species to their environment. The first option is incorrect because natural selection affects all species, not just extinct ones. The third option is wrong as natural selection selects for traits suitable for the environment, not less suitable.

Answer:

It drives the adaptation of species to their environment.
