I've speculated before that Polynesians, Icelanders, and perhaps Serbo-Croatians all evolved great size, muscular bulk, and short limbs as an adaptation to wet cold. I know that one of the most distinctive Polynesian physical traits, thick thighs, are also seen in Scandinavians.

I advise you to read Phillip Houghton’s theories on the evolution of Polynesian morphology. It’s an incredible story of how cold-nights on the water required thickness around the bone, but hot equatorial days selected against fat, due to fat having insultative properties.
