Males with big tails are liked by females and chosen to mate

History of Peacocks

Not all peacocks had large, bright tails thousands of years ago. The certain males with tails that were more desired by females were able to reproduce and pass on the traits for big, colorful tails.

Females were attracted to brighter tails

This became an example of natural selection because the male peacocks with bigger and brighter tails were selected by female peacocks
