Explanation / Answer

The process that drives adaptive changes between males and females and leads to an increased ability to attract a mate are referred to as sexual selection.

Because female produce few eggs compared to the many sperm that males produce, females choose a male with the best fitness or the ability to produce surviving young

The natural selection suggests that females select males based on their traits that increase survival.

The sexual selection hypothesis suggests that females choose males based on appearance alone.

An example of the runaway hypothesis is that cardinals exhibit sexual dimorphism, meaning that males are large and colorful,whereas females are smaller and less colorful.

It's possible that females chose colorful males because their choice indicates the increase potential for their offspring to be chosen by females, thus passing on their genes, consistent with the good genes hypothesis

Or, it's possible that females choose colorful males because the bright plumage indicates the male's health and vigor, consistent with the runaway hypothesis
