Recent research by scientists suggests that Neanderthal Man who roamed the earth 50,000 years ago were wiped out by global freezing.
Neanderthals were thought to be stupid but there is now evidence that they actually made tools and used make up and were seemingly more intelligent than we used to believe.
They did believe the earth was flat however but we cannot blame them for that as most humans actually believed this even 1800 years aftr a man was nailed to a cross.
What killed of our distant relatives the neanderthals was they were just as gullible listening to politicians as we are.
It seems they listened to the Global warming theories of Al Gorestone instead of the believes of Fred Freezestone.
The result Global warming never happened the neanderthals never took steps to protect themselves from the freezing cold and died off in an ice age.
