Question

place the steps of the process of evolution in order, beginning with the original population and ending with an evolved population that has different traits. original population evolved population answer bank genetic variation differential reproductive success selective pressure change in gene frequencies over time

Explanation:

Genetic variation first occurs within the original population. Selective pressure then acts on this variation. Organisms with traits better - suited to the selective pressure have differential reproductive success. Over time, this leads to a change in gene frequencies, resulting in an evolved population.

Answer:

1. genetic variation
2. selective pressure
3. differential reproductive success
4. change in gene frequencies over time
