Sexual selection and speciation
Trends in Ecology and Evolution, 2001The power of sexual selection to drive changes in mate recognition traits gives it the potential to be a potent force in speciation. Much of the evidence to support this possibility comes from comparative studies that examine differences in the number of species between clades that apparently differ in the intensity of sexual selection.

Competition over mates takes many forms and has far-reaching consequences for many organisms. Recent work suggests that relative reproductive rates of males and females, sperm competition and quality variation among mates affect the strength of sexual selection.

This chapter examines sexual selection. Like all other mammals, we are each male or female, and both must participate to produce offspring. Many other species, however, regularly reproduce with no appearance of either sex or gender. Sex is associated with reproduction in species like our own, but it is certainly not necessary for it.

Recent studies of a variety of polygynously mating animals indicate that females do not always choose mates independently, but instead may copy the choices of others. Copying could serve either to increase the accuracy of mate assessment or to reduce its costs. It is also likely to affect the intensity of sexual selection.
