Work Step by Step

Sexual selection causes sexual dimorphism, the differences between the sexes, because one sex favors certain characteristics in the other sex. Male aggression is also the product of sexual selection; males that are more aggressive will fight hard for the right to mate with females. Exaggerated traits such as a male peacock's tail feathers also arose from sexual selection. Females tend to favor males with these exaggerated traits because they seem to stand out and are likely to be the most healthy and vigorous; males with these traits are able to mate more frequently and pass on more of their genes to the next generation.
