Sex at Dawn

In the following chapters, we reconsider these and other aspects of social behavior, rearranging them to form a different view of our past. We believe our model goes much farther toward explaining how we got to where we are today and most importantly, why many, if not most, sexually dysfunctional marriages are nobody’s fault. We’ll show why a great deal of the information we receive about human sexuality—particularly that received from some evolutionary psychologists—is mistaken, based upon unfounded, outdated assumptions going back to Darwin and beyond. Too many scientists are hard at work trying to complete the wrong puzzle, struggling to force their findings into preconceived, culturally approved notions of what they think human sexuality should be rather than letting the pieces of information fall where they may.

Our model might strike you as absurd, salacious, insulting, scandalous, fascinating, depressing, illuminating, or obvious. But whether or not you are comfortable with what we present here, we hope you’ll keep reading. We are not advocating any particular response to the information we’ve put together. Frankly, we’re not sure what to do with it ourselves.

Undoubtedly, some readers will react emotionally to our “scandalous” model of human sexuality. Our interpretation of the data will be dismissed and derided by stalwart souls defending the ramparts of the standard narrative. They’ll be shouting, “Remember the Alamo!” But our advice, as we lead you through this story of unwarranted assumptions, desperate conjecture, and mistaken conclusions, is to forget the Alamo, but always remember the Yucatan.

CHAPTER TWO

What Darwin Didn’t Know About Sex

We are not here concerned with hopes or fears, only with truth as far as our reason permits us to discover it.

CHARLES DARWIN, The Descent of Man

A fig leaf can hide many things, but a human erection isn’t one of them. The standard narrative of the origins and nature of human sexuality claims to explain the development of a deceitful, reluctant sort of sexual monogamy. According to this oft-told tale, heterosexual men and women are pawns in a proxy war directed by our opposed genetic agendas. The whole catastrophe, we’re told, results from the basic

biological designs of males and females. Men strain to spread their cheap and plentiful seed far and wide (while still trying to control one or a few females in order to increase their paternity certainty). Meanwhile, women are guarding their limited supply of metabolically expensive eggs from unworthy suitors. But once they’ve roped in a provider-husband, they’re quick to hike up their skirts (when ovulating) for quick-and-dirty clandestine mating opportunities with square-jawed men of obvious genetic superiority. It’s not a pretty picture.

Biologist Joan Roughgarden points out that it’s an image little changed from that described by Darwin 150 years ago. “The Darwinian narrative of sex roles is not some quaint anachronism,” she writes. “Restated in today’s biological jargon, the narrative is considered proven scientific fact.... Sexual selection’s view of nature emphasizes conflict, deceit, and dirty gene pools.”¹

No less an authority than The Advice Goddess herself (syndicated columnist Amy Alkon) voices the popularized expression of this oft-told tale: “There are a lot of really bad places to be a single mother, but probably one of the worst ever was 1.8 million years ago on the savannah. The ancestral women who successfully passed their genes on to us were those who were choosy about who they went under a bush with, weeding out the dads from the cads. Men had a different genetic imperative—to avoid bringing home the bison for kids who weren’t theirs—and evolved to regard girls who give it up too easily as too high risk for anything beyond a roll on the rock pile.”² Note how so much fits into this tidy package: the vulnerabilities of motherhood, separating dads from cads, paternal investment, jealousy, and the sexual double standard. But as they say at the airport, beware of tidy packages you didn’t pack yourself.

As for an English lady, I have almost forgotten what she is.—something very angelic and good.
