It's true, dancing does lead to sex

SCIENTISTS have confirmed what fans of John Travolta in Saturday Night Fever have known all along: men with the best dance moves have the most sex appeal. The finding lends support to the idea that dancing is a way to show off high quality genes and good health - both indicators of a top quality mate.

Charles Darwin was the first to suggest that dance was a courtship signal in animals, but there had been no studies of the relation of dance and genetic or physical quality in humans until now. In a study published yesterday in the journal Nature, William Brown, of Rutgers University in New Jersey, looked at how dancing ability correlated with a person's body symmetry, a typical measure of the quality of a mate in evolutionary biology. Across a wide range of species, less-symmetric bodies are associated with increased disease and poor reproductivity.

Professor Brown recorded 183 Jamaicans strutting their stuff and then presented the results to 155 peers for evaluation on a dance rating scale. The body symmetry of the participants was assessed by matching their elbows, wrists, knees, ankles, feet, ears and third, fourth and fifth fingers. Professor Brown found that symmetrical men were evaluated as significantly better dancers than asymmetric ones. Likewise, men preferred the dances of symmetrical women, although this effect was not as marked, suggesting women are more choosy in selecting mates.

However, the researchers stopped short of saying why symmetry was so crucial, and said more study was necessary. "Attractive dances may be more difficult to perform, more rhythmic, more energetic, more energy-efficient or any combination of these factors," they write. "Does dance ability correlate with reproductive success? We plan to address this question with long-term data from the same population."

My comment:
Now, if there ever was any doubt that women LOVE a man who can dance, it's been irrefutably proven that they do. For decades, some of the sexiest men in film have wowed female audiences with their dance moves. Were they sexy before they started dancing? Some were, others, not so much. But it cannot be denied that there's something special about a man who can take command on the dance floor.
