Why is Genetic Variation Critical for Evolution

Question

Why is genetic variation critical for evolution?
A)It is required for mutations.
B)It is the source material for natural selection.
C)It is essential for adaptation.
D)It is essential for genetic recombination.
E)It is not critical for evolution.

Accepted Answer

Genetic variation is the source material for natural selection. Natural selection acts on the genetic variation within a population, favoring individuals with traits that are better suited to their environment. This leads to the evolution of new species and the adaptation of existing species to changing environments.
