The Short Answer

I've always looked at it as it has to do with being symmetrical. You can divide even numbers into two equal halves. When you look at someone and find them attractive their face is normally symmetrical. People without birth defects have symmetrical sides of the body, two arms, two legs, ten fingers and so on. This might not be as scientific as you were wanting, just my two cents.
