Neanderthals could have died out because their bodies overheated
Analysis of DNA obtained from Neanderthal remains has revealed key differences from modern humans that suggest 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 reasoning in this silly premise would have us believe that the physiology of the peoples of the polar regions today is different than that of those in the more temperate regions. Does anyone believe that the Fins, Danes, Aleuts, etc., would vanish if their land warmed up? Take it up a notch in silliness, how does today's concern for the polar bear compare to the poor Neanderthal in their day? This is a new low in conjecture but the Al Gores of the world will use it to prove mankind is doomed unless we forsake the modern conveniences that keep us comfortable and mobile.

Gee! We are in trouble then...just the introduction of a swarm of homo sapiens, and their increased use of fire, caused global warming so bad that it wiped-out the Neanderthals! ;~)
