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.
If that sounds remarkably like what H.G. Wells foresaw in "The Time Machine" with his Eloi and Morlocks, that's because 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 tells the testosterone-heavy British "men's television" satellite channel Bravo — not to be confused with its more gracile American namesake — that human evolution will reach its peak in about the year 3000.
By then, sexual selection will have bred men into tall, handsome studs with deep voices, square jaws and substantial penises. Their female counterparts will have smooth, hairless skin, glossy hair, large eyes and perky breasts, says Curry.
But after that, it's all downhill.
"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," Curry says, according to London's Daily Mail. "After that, things could get ugly, with the possible emergence of genetic 'haves' and 'have-nots.'"
