A study of Jamaican men, published in the journal Nature, found that there are strong positive associations between symmetry and dancing ability, and these associations were stronger in men than in women.
In addition, women rate dances by symmetrical men relatively more positively than do men, and more-symmetrical men value symmetry in women dancers more than do less-symmetrical men.
One measure of quality in evolutionary studies is the degree of bodily symmetry, because it measures developmental stability, the study said.
