Hey look, someone else has my theory.
Humanity may split into two sub-species in 100,000 years' time as predicted by HG Wells, an expert has said.
Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge.
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.
The only difference is, I don’t think we’re going to be on the planet that long.
