Sex at Dawn
Since Darwin’s Origin of the Species, we’ve been told that sexual monogamy comes natural. Mainstream science, as well as religious and cultural institutions, has maintained that men and women evolved in families in which a man’s possessions and protection were exchanged for a woman’s fertility and fidelity.
In this groundbreaking book, however, Christopher Ryan and Cacilda Jethá argue that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together evidence from anthropology, archaeology, anatomy, and psychosexuality, the author’s show how far from human nature monogamy really is.
Reading the book I understand that Ryan and Jethá try to explain how our promiscuous …show more content…

I turn now to the next, and most important, aspect of Ryan and Jethá’s narrative: the nature of ancestral human sexuality. As mentioned above, the adoption of the bonobo model lays the foundation for their conception of ancestral mating as promiscuous and fluid, and males unconcerned with paternity. Flowing from the bonobo model combined with the ethics of generosity and reciprocation described as vitally important to “fiercely egalitarian” modern foragers, is their hypothesis that “Socio-Erotic Exchanges (S.E.Ex. for short) strengthen the bonds among individuals in small-scale nomadic societies, forming a crucial, durable web of affection, affiliation, and mutual obligation”. In addition, they go on to note that “Without frequent S.E.Ex., it’s doubtful that foraging bands could have maintained social equilibrium and fecundity over the millennia”.
Still working on the similarities and differences between humans and their ancestries, in Sex at Dawn we can find, for example, a very interesting discussion about human female orgasm, in where the authors of the book point out that female orgasmic behavior has been observed in some primate species with multimale- multifemale mating systems, whereas the monogamous gibbon female does not exhibit such behavior. Following this, Symons’ (1979) by-product argument is summarized, and a few pages later, changes in vaginal
