Pallab Ghosh reports on a new study about what makes some male dancers better than others and why "good dancing may be indicative of good health and reproductive potential." Evolutionary psychologist and co-author Dr. Nick Neave was surprised by what they found:
We thought that people's arms and legs would be really important. The kind of expressive gestures the hands [make], for example. But in fact this was not the case.
We found that (women paid more attention to) the core body region: the torso, the neck, the head. It was not just the speed of the movements, it was also the variability of the movement. So someone who is twisting, bending, moving, nodding.
Video above is the example of the good, the bad is after the jump.
