Question

Selection can act only on the level of the individual; nothing on a larger scale and nothing on a smaller scale. True or False?

1) True
2) False

Answer 1

Natural selection does act on the level of the individual, but it can also act on phenotypic variations in populations.

Step-by-step explanation:

The statement is False.

Natural selection acts at the level of the individual by selecting for individuals with greater contributions to the gene pool of the next generation. This is known as an organism's evolutionary fitness. However, natural selection can also act on phenotypic variations in populations, not just at the individual level.

For example, if a certain trait provides a reproductive advantage, individuals with that trait are more likely to survive and pass on the trait to their offspring, increasing its frequency in the population over time.
