Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection or non-adaptive by-products of other adaptive traits.
Orgasm or sexual climax is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region. Orgasms are controlled by the involuntary or autonomic nervous system and experienced by both males and females; the body's response includes muscular spasms, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, after the release of the neurohormones oxytocin and prolactin, as well as endorphins.
The Trobriand Islands are a 450-square-kilometre (174-square-mile) archipelago of coral atolls off the east coast of New Guinea. They are part of the nation of Papua New Guinea and are in Milne Bay Province. Most of the population of 60,000 (2016) indigenous inhabitants live on the main island of Kiriwina, which is also the location of the government station, Losuia.

Partible paternity or shared paternity is a cultural conceptualization of paternity according to which a child is understood to have more than one father; for example, because of an ideology that sees pregnancy as the cumulative result of multiple acts of sexual intercourse. In societies with the concept of partible paternity this often results in the nurture of a child being shared by multiple fathers in a form of polyandric relation to the mother, although this is not always the case.
Donald Symons was an American anthropologist best known as one of the founders of evolutionary psychology, and for pioneering the study of human sexuality from an evolutionary perspective. He is one of the most cited researchers in contemporary sex research. His work is referenced by scientists investigating an extremely diverse range of sexual phenomena. Harvard psychologist Steven Pinker describes Symons' The Evolution of Human Sexuality (1979) as a "groundbreaking book" and "a landmark in its synthesis of evolutionary biology, anthropology, physiology, psychology, fiction, and cultural analysis, written with a combination of rigor and wit. It was a model for all subsequent books that apply evolution to human affairs, particularly mine." Symons is Professor Emeritus in the Department of Anthropology at the University of California, Santa Barbara. His most recent work, with Catherine Salmon, is Warrior Lovers, an evolutionary analysis of slash fiction.
Veneer theory is a term coined by Dutch primatologist Frans de Waal to label the Hobbesian view of human morality that he criticizes throughout his work. Although he criticizes this view in earlier works, the term in this form is introduced in his 2005 book Our Inner Ape, denoting a concept that he rejects, namely that human morality is "a cultural overlay, a thin veneer hiding an otherwise selfish and brutish nature". The idea of the veneer theory goes back to Thomas Henry Huxley and has more recently been advocated by biologists like George C. Williams.
A Natural History of Rape: Biological Bases of Sexual Coercion is a 2000 book by biologist Randy Thornhill and anthropologist Craig T. Palmer, in which the authors argue that evolutionary psychology can account for rape among human beings, maintain that rape is either a behavioral adaptation or a byproduct of adaptive traits such as sexual desire and aggressiveness, and make proposals for preventing rape. They also criticize the assumption that there is a connection between what is naturally selected and what is morally right or wrong, which they refer to as the "naturalistic fallacy", and the idea, popularized by the feminist author Susan Brownmiller in Against Our Will (1975), that rape is an expression of male domination and is not sexually motivated.

Sex at Dawn: The Prehistoric Origins of Modern Sexuality is a 2010 book about the evolution of human mating systems by Christopher Ryan and Cacilda Jethá. In opposition to what the authors see as the "standard narrative" of human sexual evolution, they contend that having multiple sexual partners was common and accepted in the environment of evolutionary adaptedness. The authors contend that mobile, self-contained groups of hunter-gatherers were the norm for humans before agriculture led to high population density. Before agriculture, according to the authors, sex was relatively promiscuous and paternity was not a concern. This dynamic is similar to the mating system of bonobos. According to the book, sexual interactions strengthened the bond of trust in the groups. Far from causing jealousy, social equilibrium and reciprocal obligation were strengthened by playful sexual interactions.
Darrel Wayne Ray is an American organizational psychologist and author who focuses on topics such as workplace organizational culture, secular sexuality, and the treatment of religion-induced trauma.

Female copulatory vocalizations, also called female copulation calls or coital vocalizations, are produced by female primates, including human females, and female non-primates. They are not purposeful, but instead are evolutionary and are spontaneously produced by female primates, including women, to encourage her partner to produce good-quality sperm during the mating process. Copulatory vocalizations usually occur during copulation and are hence related to sexual activity. Vocalizations that occur before intercourse, for the purpose of attracting mates, are known as mating calls.
Randy Thornhill is an American entomologist and evolutionary biologist. He is a professor of biology at the University of New Mexico, and was president of the Human Behavior and Evolution Society from 2011 to 2013. He is known for his evolutionary explanation of rape as well as his work on insect mating systems and the parasite-stress theory.
The Evolution of Human Sexuality is a 1979 book about human sexuality by the anthropologist Donald Symons, in which the author discusses topics such as human sexual anatomy, ovulation, orgasm, homosexuality, sexual promiscuity, and rape, attempting to show how evolutionary concepts can be applied to humans. Symons argues that the female orgasm is not an adaptive trait and that women have the capacity for it only because orgasm is adaptive for men, and that differences between the sexual behavior of male and female homosexuals help to show underlying differences between male and female sexuality. In his view, homosexual men tend to be sexually promiscuous because of the tendency of men in general to desire sex with a large number of partners, a tendency that in heterosexual men is usually restrained by women's typical lack of interest in promiscuous sex. Symons also argues that rape can be explained in evolutionary terms and feminist claims that it is not sexually motivated are incorrect.
