How NEANDERTHAL got his big nose

LONDON: Anthropologists have suggested that Neanderthals had big noses because of the degree to which their face used to jut forward, indicating that the odd feature was a fluke of evolution, not some grand adaptation. 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. Big noses tend to be found in people whose ancestors evolved in tropical climates
, where a large nasal opening helps cool the body. But Neanderthals go against this trend, according to Tim Weaver, a palaeoanthropologist at the University of California, Davis. "They were living in the glacial environment of Europe, colder than it is today, for most of the time," he said. "So, it's sort of been an anomaly. Why do they have these wide nasal apertures?," he wondered.

I think the larger nose if for gathering more air for the sole purpose of scent.

I seem to recall seeing something that said that larger noses helped to prevent sweating whilst hunting etc under heavy clothing. Sweat that would freeze... or something of that nature.
