Animal attraction dating
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.
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.
Women with a WHR of 0.7—indicating a waist significantly narrower than the hips—are most desirable to men.
Hands down, the women found the scent of a symmetrical man to be more attractive and desirable, especially if the woman was menstruating.But the role of pheromones in the human realm remains controversial.Animal attraction Pheromones clearly act as sexual attractants in the animal world.By questioning the study participants, Thornhill also found that men with higher degrees of symmetry enjoy more sexual partners than men of lower symmetry."Women's sex-partner numbers are dependent on things other than attractiveness," Thornhill told .They have to be wooed and all that."Those hips Body shape is of course important, too. Psychologist Devendra Singh of the University of Texas studied people's waist-to-hip ratio (WHR).
In the end, lasting love depends at least as much on behavior as biology.
