Scientists reveal the best and worst dance moves for women

It's a question that has plagued humanity through the ages: What moves make all the difference when you hit the dance floor? Researchers have found that the sexiest dancers move their hips a lot, and shift their arms and thighs independently of one another. Scientists suggest that there could be evolutionary benefits to the dance moves we enjoy most. For example, they suggest that hip swing may be an explicitly feminine trait that shows fertility and youth. The ability to move limbs independently of one another could reveal good motor control, and hence healthy genes for procreation.
