Dancing is something that all humans do, but scientists aren't exactly sure why. Boogying has probably never saved your life. Instead, it eats up time and energy that you could have used to find your next meal or to raise some offspring. But across cultures, dancing tends to be involved in courtship rituals, so perhaps dancing evolved as a way to show off your quality as a potential mate. This team hopes that by understanding the characteristics of good dancing, we can understand more about its evolutionary function.
