According to the BBC, evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge. The human race would peak in the year 3000, he said - before a decline due to dependence on technology. He added:

People would become choosier about their sexual partners, causing humanity to divide into sub-species.

The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the “underclass” humans who would have evolved into dim-witted, ugly, squat goblin-like creatures.

Hasn’t this guy kept abreast of existing evolutionary developments? The “underclass” is already here; it is called religious fundies!
