Also note how today's primate species constantly fight for prime territories in Earth's coldest regions

London, Dec 21 (ANI): Neanderthals could have died out because their bodies overheated as the Earth grew warmer, says a new research. According to the analysis of DNA obtained from Neanderthal remains, which revealed key differences from modern humans, their bodies produced excess heat.

While in the cold climate of an ice age this would have provided the species with an advantage, as the earth warmed they would have been less able to cope. Ultimately this would have caused their extinction around 24,000 years ago, the scientists say.
