Question

An example of natural selection is the tail of a male peacock. The females of the species choose mates based on the colors of the males’ tail feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time?

Answer 1

Because the current criteria is color and because we don't know whether or not there is any other use for the tails, so the only safe conclusion would be that "the tails' colors would probably less vibrant".
