Question

For evolution to take place, a population must have both ______ and ______.

Answer 1

For evolution to take place, a population must have both genetic variability and differential reproduction.

Explanation:

Genetic variability provides the raw material for evolution by introducing differences among individuals in a population. Differential reproduction means that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to the next generation. Together, these factors drive the process of natural selection and evolutionary change within populations.
