If a man in a bar spots a woman with a symmetrical face and a 0.7 waist-to-hip ratio, and if she detects in the scent of his sweat the promise of an immune system that complements her own, the Valentine flowers may be superfluous.
In "Naked Science: What's Sexy?" (National Geographic Channel, Monday, 9:00 p.m. EDT), the anthropologist Helen Fisher and other scientists explain how humans broadcast reproductive compatibility in a predictable mating process that includes three stages: lust, love and attachment.
A National Geographic special shows how science determines what's sexy.
When he whispers "ooohh, baby," he's getting right to the point, since conceiving -- i.e., passing on one's DNA -- is the payoff. While testosterone does the job in the bar, at the stage when men seek to maximize mating opportunities, dopamine fuels the intensity of love; and oxytocin seems to be the Krazy Glue that keeps us faithful, promoting long-term attachment.
Much of this evolutionary psychology is familiar, and Dr. Fisher has become something of a one-woman industry, translating for the dating/copulating public the stuff of dissertations. Dr. Fisher's image spins around in MTV-style sequences, and demotic terms like "hot" (used here to describe sexual attractiveness) are an irritant.
Yet some of the studies are revelatory. In one, women are shown to prefer the sweat of men with immune systems different from their own. (Their potential offspring would be protected by the complementary arsenal of disease-fighting genes.) In another, women's hands and ears become more symmetrical, hence more alluring, 24 hours before ovulation.
Men like to look, of course, and a 26-inch waist and 37-inch hips, visual cues that reliably ignite male ardor, are ideal for childbearing (such measurements yield more pregnancies earlier in life, and fewer miscarriages).
But more intriguing is what we learn about women, and men should be warned: If a woman asks, "Will you call me?" and he fails to do so, a mental note is being blow-torched into her DNA.
Women size men up not only by evaluating wealth and status but also by processing memory, creating a map in the brain's hippocampus. Did he call? And what did he get her for Valentine's Day? According to Dr. Fisher, when women talk on the phone, comparing notes on their menfolk, they're reinforcing this punctilious database.
With $13 billion spent on plastic surgery in the U.S. in 2004, women are now adept at creating a false image of fertility to get them through the "lust" stage. But those full breasts won't be passed on genetically; as a form of Darwinian backlash, such "manmade" couplings could lead to less sexually attractive future generations. Fortunately, you can't fake intelligence and kindness -- at least not yet. And these, we learn, are the traits most sought after in a human mate, across cultures.
We also get practical advice. It seems men are aroused by feelings of fear and anxiety, and that women might try propositioning them under frightening circumstances. And, now that they know women are keeping a permanent record of their behavior, men may have reason to be afraid.
