At least since Darwin, scientists have suspected that dance so often plays a role in courtship because dance quality tracks with mate quality. By using motion-capture technology ... we can confidently peg dancing ability to desirability.

At least since Darwin, scientists have suspected that dance so often plays a role in courtship because dance quality tracks with mate quality. But this has been hard to study because of the difficulty of isolating dance movements from variables, such as attractiveness, clothing and body features. By using motion-capture technology commonly employed in medical and sports science to isolate dance movements, we can confidently peg dancing ability to desirability.

Look at the numbers and quality of the engineers and scientists they produce and you know that this is where the R&D will be done. The Chinese have a space program, they are going to put a man on the moon and nobody sold them that technology.

With motion capture, we can do that and get just pure dance movements.

As you're developing, all sorts of things come at you, like diseases and injury. If you're able to develop symmetry despite all of that, then that would indicate to others that you have what it takes to make a go of it in that environment.

There is too little courtship in the world.
