The human race may split in the next 100,000 years, according to a British scientist.

Oliver Curry, an evolutionary psychologist at the London School of Economics, thinks two subspecies will emerge: a tall, slim, intelligent privileged class, and a short, squat, ugly, dim-witted race of servants.

The division of species into slender "gracile" and husky "robust" forms occurs repeatedly in the evolutionary history of higher primates.

For example, the common chimpanzees is a tough, violent, meat-eating ape, while its close relative the bonobo is a slimmer, more gentle, largely vegetarian peace-lover.

Curry says that human evolution will reach its peak in about the year 3,000.

"There is the possibility of a monumental genetic hangover over the subsequent millennia due to an over-reliance on technology reducing our natural capacity to resist disease, or our evolved ability to get along with each other," he says. "After that, things could get ugly, with the possible emergence of genetic 'haves' and 'have-nots.
