Sexual dismorphism and sexual selection

Sexual Dimorphism and Sexual Selection

The concept of sexual dimorphism, as a derive aspect from sexual selection, is a quite weird complexity of nature. It can be consider as one justification ofnatural selection, which is in charge of passing on the best genes from generation to generation. However, sometimes the best traits don’t seem very appropriate.

Bird males that show a splendid display of colorful plumage arejudiciously chosen from prospect sexual mates, yet this flamboyant characteristic works against males’ own survival; their lively plumage is a perfect call for predators.
