Question: Describe one measure of evolutionary fitness.

One measure of evolutionary fitness is the concept of Darwinian fitness, which refers to the relative reproductive success of an individual or genotype within a given environment. It is not merely about physical strength or survival, but rather the ability to pass on genetic information to subsequent generations. In essence, it's a measure of how well an organism's characteristics are suited to its environment, influencing its chances of reproduction. For example, if a particular trait or behavior increases the likelihood of an organism finding a mate and producing offspring, that trait is considered to contribute positively to its Darwinian fitness. This measure is crucial in the study of natural selection, as it helps explain why certain traits become more common in a population over time.
