Sexual selection is generally strongest in males but there is a great diversity of sex roles across the tree of life, including reversals [ 1 ]. Sex differences in sexual selection often coincide with contrasting mating interests or optimal phenotypes of males and females i.

Our understanding of sexual selection comes largely from studies of competition among males for access to females and female choice, with the products of sexual selection including exaggerated male weapons and ornaments. In contrast sexual selection acting on females is poorly understood, and indeed highly debated. In this virtual issue we revisit this debate and highlight some of the articles that have examined reproductive competition among females and its evolutionary consequences for female sexual signalling. Intrasexual competition in females: evidence for sexual selection?

Sexual selection in humans concerns the concept of sexual selectionintroduced by Charles Darwin as an element of his theory of natural selection[1] as it affects humans. The role of sexual selection in human evolution has not been firmly established although neoteny has been cited as being caused by human sexual selection. Some hypotheses about the evolution of the human brain argue that it is a sexually selected trait, as it would not confer enough fitness in itself relative to its high maintenance costs a quarter to a fifth of the energy and oxygen consumed by a human.
