Question

An example of natural selection is the tail of a male peawingspan. 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 peawingspans over time?

Answer 1

They wouldn't breed with a peawingspan for a certain color of tail feather, so that trait wouldn't be passed of to the offspring. Instead, the other trait that the females use to choose mates would be seen in the offspring.

Answer 2

They wouldnt be as flashy as before as they are no longer needed so instead their bodies will focus more on the traits that are looked for in mating.
