Huge swarms of humans killed off Neanderthals

Neanderthals died out in Western Europe after a huge surge of modern humans arrived suddenly from Africa and made them a minority in their own land, researchers claim.

The swarm of Homo sapiens onto the continent more than 40,000 years ago left the Neanderthals, who had thrived in the frigid conditions for 300 millennia, outnumbered by a massive 10 to one.

The invasion of so many modern humans overturned the neanderthals' domination of the land and forced them into fierce competition for food, fuel and other crucial resources.

The scenario, described by Paul Mellars, emeritus professor of prehistory and human evolution at Cambridge University, and his colleague, Jennifer French, is the latest attempt by scientists to explain the mystery of the Neanderthals' demise.
