If You Want Fidelity, Get a Dog

Christopher Ryan, psychologist and co-author (with his wife) of Sex at Dawn, debunks the culturally instilled notion that monogamy comes naturally to the human species.  Speaking at a conference in Australia last year, he overviews the history of human sexuality as presented in his book.  His talk can be found on YouTube by searching on: christopher ryan monogamy.  He presents many interesting facts and conclusions, making the video well worth the invested time of fifty-seven minutes.
