Description Edit Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.

This way of choosing a mate is just one type of sexual selection: members of one sex mating in disproportionate numbers with members of the opposite sex that possess some "showy" feature. It might be ornate peacock plumage, large antlers on a deer, or a bird's particularly melodious mating call. Another type of sexual selection is combat among members of the same sex to choose an available mate.
