Question

When a population is split into smaller groups, why do these groups develop different traits?

Answer 1

Answer:

C. Forces like natural selection and genetic drift affect the genes of the two subgroups diffidently.

Explanation:

For example, a group of finches separate do to something out of the blue. Over time, one group may evolve and develop traits that make them different from the original group, like larger or smaller beaks. The genetic drift comes into play since the genes that affect the physical and mental behaviors are being created or switched around.
