Hmm, I find it kind of suspicious that an organ would evolve to project
out from the face simply to keep the lungs a fraction of a degree warmer.
Wouldn't the potential for frost bite on the nose be more of a
disadvantage than the advantage of warming the air? I've never heard of
humans dying from breathing cold air, but I do know that humans die from
I don't think the nose's origin has anything to do with warming the air.
If our bodies are a result of adaptation to the cold, I would think that
there would be many other areas that would have resulted in adaptations
first, for example growing hair.
