Why did Neanderthals have such big noses?: "The Neanderthal's huge nose is a fluke of evolution, not some grand adaptation, research suggests.

The Neanderthal nose has been a matter of befuddlement for anthropologists, who point out that modern cold-adapted humans have narrow noses to moisten and warm air as it enters the lung, and reduce water and heat loss during exhalation."
