Men Pay the Ultimate Price to Attract Women

While it is tough to be a woman, being a man can be downright deadly.

Women live longer than men. And now scientists suggest a simple Darwinian reason: Competing for a mate can wear a guy out or get him killed.

"Women live longer in almost every country, and the sex difference in lifespan has been recognized since at least the mid-18th century," said Daniel Kruger at the University of Michigan. "It isn't a recent trend; it originates from our deep evolutionary history."

The idea is presented in the spring edition of the journal Human Nature.

Butting heads

In common chimpanzees, Kruger and his colleague Randolph Nesse report, mortality spikes among males around age 13, just as they're old enough to breed and start competing for social status.

Males of many species must fight vigorously for the right to mate. Think of rams butting heads. Spectacular male bird plumage is another example of biological effort required to succeed, effort that uses energy and can shorten a life.

In this scheme of natural selection, evolution shapes traits that help the best genes survive, sometimes to the detriment of individuals.

Human males don't always have to wrestle to get a woman these days, but the pressure to succeed sexually hasn't changed much, the researchers argue. Only the methods have been revised.

Though society may be changing dramatically even from this generation compared to the last, some things never change. Women still have to bear the greatest burden of raising a family

To figure out how we pick mates, scientists have measured every shape and angle of the human face, studied the symmetry of dancers, crafted formulas from the measurements of Playboy models, and had both men and women rank attractiveness based on smelling armpit sweat.

After all this and more, the rules of attraction for the human species are still not clearly understood. How it all factors into true love is even more mysterious.

But a short list of scientific rules for the game of love is emerging. Some are as clearly defined as the prominent, feminine eyes of a supermodel or the desirable hips of a well-built man. Other rules work at the subconscious level, motivating us to action for evolutionary reasons that are tucked inside clouds of infatuation.

In the end, lasting love depends at least as much on behavior as biology. But the first moves are made before you're even born.

Starting at conception, the human body develops by neatly splitting cells. If every division were to go perfectly, the result would be a baby whose left and right sides are mirror images. But nature doesn't work that way. Genetic mutations and environmental pressures skew symmetry, and the results have lifelong implications.

Good symmetry shows that an individual has the genetic goods to survive development, is healthy, and is a good and fertile choice for mating.

"It makes sense to use symmetry variation in mate choice," said evolutionary biologist Randy Thornhill of the University of New Mexico. "If you choose a perfectly symmetrical partner and reproduce with them, your offspring will have a better chance of being symmetric and able to deal with perturbations."

Thornhill has been studying symmetry for 15 years and scanned faces and bodies into computers to determine symmetry ratios. Both men and women rated symmetrical members of the opposite sex as more attractive and in better health than their less symmetrical counterparts. The differences can be just a few percent
