>Answer:  Yes.  The principal difference is the Arctic peoples have shorter
limbs and larger trunks, which provides some protection from the cold
weather.  Shorter limbs means less surface area that is exposed to the cold,
and larger trunk (chest and body) promotes conservation of warm temperature
in the blood stream.
