“Christopher Ryan and Cacilda Jethá have written the essential corrective to the evolutionary psychology literature. Sex at Dawn irrefutably shows that the urgent sexuality that is everywhere apparent in human society and which requires layers of religious, social, and psychological suppression was likewise a constant feature on the African savanna. The more dubious its evidentiary basis and lack of connection with current reality, the more ardently the scientific inevitability of monogamy is maintained -- even as it falls away around us.  Thus Darwin and science have been corralled into the business of fomenting useless, irrational guilt. Drs. Ryan and Jethá make this all as transparent as glass, and do it with élan.”
