The answer to why we dance - and even why some people are better dancers than others - can be found in evolution. A study published in the Public Library of Science's genetics journal in 2006 suggested that long ago the ability to dance was actually connected to the ability to survive.

According to the study, dancing was a way for our prehistoric ancestors to bond and communicate, particularly during tough times. As a result, scientists believe that early humans who were coordinated and rhythmic could have had an evolutionary advantage.

The researchers examined the DNA of a group of dancers and non-dancers and found that the dancers shared two genes associated with a predisposition for being good social communicators. In addition, the dancers were found to have higher levels of serotonin, known to boost moods in humans and mice.

Early humans might have danced to attract a mate, as far back as 1.5 million years ago, according to Steven J. Mithen, an archaeologist at the University of Reading in the United Kingdom.
