At least several important evolutionary changes in humans and animal species, that were considered by Darwin to be as a result of sexual selection (like human skin color, the stripes of a tiger or the sounds of a rattlesnake), are today believed to have been formed under the pressure of natural selection.
On the other hand, when it comes to the origins of energetically costly and ostensibly non-adaptive human activities such as singing and dancing, the idea of sexual selection is still very popular (see for example, Miller, 2000). Miller, arguably the most ardent and influential contemporary proponent of sexual selection in human evolution, argues that not only the arts, but even the development of the human languages and the evolution of higher intelligence are the result of the...
