Moves Like Jagger

Back in 1871, Charles Darwin (1809-1882) published The Descent of Man, and Selection in Relation to Sex, in which he argues, among other things, that human females, like the females of most species, play a large role in choosing mates. As their choices are usually based on perceived physical superiority and health, those are the traits that are passed down and survive. Sometimes the physical show put on by the males of a species are blatant (a peacock's tail), and sometimes they are less so. A recent finding falls into the first category. Researchers in the UK say their results show that the way a man dances can telegraph information about his health and, therefore, his viability as a mate. "We found that [women paid more attention to] the core body region: the torso, the neck, the head," explained evolutionary psychologist Dr. Nick Neave. "It was not just the speed of the movements, it was also the variability of the movement" (story, video): http://www.bbc.com/news/science-environment-11223473
