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.

These subconscious scents might be related to pheromones, chemical signals produced by the body to communicate reproductive quality.

The human genome contains more than 1,000 olfactory genes—compared to approximately 300 genes for photoreceptors in the eyes—so pheromones have received a lot of attention from basic research scientists as well as perfume manufacturers.

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—perceivable though not necessarily noticeable.

Animal attraction Pheromones clearly act as sexual attractants in the animal world.

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.

In general, a range of 0.67 to 1.18 in females is attractive to men, Singh concluded in a 2004 study, while a 0.8 to 1.0 WHR in men is attractive to women, although having broad shoulders is more of a turn-on. A big fat clue to whether the person will have enough energy to care for offspring.

Where fat is deposited on the body is determined by sex hormones; testosterone in men and estrogen in women.
