Question

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

Answer 1

the other criteria would evolve to match what the females like. The feathers would stop evolving to the color that increased mating and would get adapted to sth else such as having camouflage(the color of their ecosystem to stay hidden from predators).
