What was the major evolutionary change that occurred in peacocks?

To help answer these questions, scientists at the University of Wisconsin-Madison studied fruit fly derrieres and found that ancient genetic switches have evolved to manipulate the appearance of animals in a way that favored their selection as mates, providing a possible explanation for how peacocks evolved their …

A female may choose a male from several because he is attractive. Looks are certainly important for the peacock, with his absurdly bright, burdensome train that he shows off to attract a female.

Why do peahens prefer to mate with peacocks with elaborate trains?

A similar phenomenon is well described in the nonhuman animal literature: Peacocks impress peahens with their large and beautiful tails, but the peahens are adaptively drawn to them because the size of the tails honestly signal the genetic quality of the peacocks, leading to a more informative sexual partner choice ( …

This sexual selection argument says that males are usually the most colorful sex because females are more likely to be in short supply due to the extra work involved in incubation and chick rearing.

What is a male peacock known for?
