Question

A key point in Darwin’s explanation of evolution is that Group of answer choices1. the biological structures most likely inherited are those that have become better suited to the environment through constant use. 2. mutations that occur are those that will help future generations fit into their environments. 3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population. 4. genes change in order to help organisms cope with problems encountered within their environments.

Answer 1

3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.

Explanation:

• Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
• Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
• Natural selection is the machine that drives evolution. It also explains adaptation.
