Question

mutations help in evolution because:
a they increase genetic variation
b they increase the potential for individuals to differ
c both a and b
d none of the above

Explanation:

Mutations introduce new genetic material. This new genetic material increases genetic variation within a population. With increased genetic variation, there is a greater potential for individuals in the population to differ from one another. These differences (due to mutations) can then be acted upon by natural selection (a key mechanism in evolution). For example, a mutation might lead to a new trait (like a different beak shape in birds). If this trait is beneficial (e.g., helps in better food - gathering), the individuals with the mutation are more likely to survive and reproduce, passing on the mutated gene.

Answer:

C. Both A and B
