The Sex Appeal of Innovation

A study of our European ancestors may propose that ancient cave women couldn't resist the sex appeal of the innovators of their time.

Looking at genetic patterns in Europeans, scientists see evidence that women from hunter/gatherer societies left their men and started procreating with the innovative farmers of their day.  Although it may be difficult to envision farmers as "innovators" amid our current society cluttered with self proclaimed social media guru's, scientists who have technology to clone you, and engineers who can design gadgets that either can make our lives easier or miserable, ancient farmers spread a disruptive technology that changed the way people lived.  They also probably really pissed off the hunters and gathers, who's genes faded throughout the centuries following the loss of their lady friends.

Who are the "farmers" and "hunters and gatherer's" of today's society?
