Expand your knowledge—with theories and concepts that may challenge your assumptions about sexual attraction Human sexuality can be better understood by knowing how sexual psychologies may have evolved throughout the ages. Handbook of the Evolution of Human Sexuality presents a detailed examination of human sexuality, the assumptions about concepts and terms pertaining to sexuality, and the latest theories on the evolution of human sexual attraction.
Leading experts explore various aspects of evolutionary theory, with a focus on Evolutionary Psychology EP. Discussions include mate preferences, mating behavior, mate signaling, pheromones, and same-sex attraction. This comprehensive source also presents three groundbreaking theories of the evolution of same-sex attraction. Handbook of the Evolution of Human Sexuality takes current assumptions about human sexuality, explains each in turn, and then offers fresh perspectives on conventional concepts of sexual orientation.
The Evolution of Sexuality pp Cite as. Sperm competition occurs when a female copulates with two or more males within a sufficiently brief time period, resulting in sperm of the different males competing to fertilize ova. Sperm competition has been documented or inferred to occur across several species. We review the evidence for sperm competition in humans. Specifically, we review literature indicating apparently convergent adaptations to sperm competition in humans and nonhumans.
We discuss future research directions and conclude that the research that documents anatomical, biological, physiological, and behavioral adaptations to human sperm competition provides compelling evidence that sperm competition has been a recurrent feature of human evolutionary history.
