Sex at Dawn
The Prehistoric Origins of Modern Sexuality

Rayn, Christopher; Jetha, Cacilda
Year Published:  2010  
Pages:  416pp   ISBN:  978-0061707803
Resource Type:  Book

Ryan and Jethá contend that humans evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors argue that monogamy is by no means part of human nature.
