human groups from hotter climates tend to be larger and lankier while groups from colder climates tend to be shorter and stockier.
A long, thin shape would have proportionately more surface area than a short, thick one of the same mass.
Consider a sheet of plywood 48 by 96 inches and 1/2 inch thick. That's 9360 square inches of surface area, according to my calculations. Now cut it into 12 inch squares - 32 squares to make a stack 16 inches high. That's 1056 square inches surface area. The short fat stack will stay much warmer than the thin sheet.

I'm South African and we "white "people are generally larger than the "bbalck people yet we originate from colder climates????
I didn't say "generally larger"; I said specifically longer and thinner. In the very post that you replied to, I demonstrated that longer, thinner shapes have more surface area to dissipate more heat than shorter, fatter shapes of the same mass. But the topic is about the heat-dissipation qualities of hair, not body shape or size.If you have nothing to say, you could have done so much more concisely. -- Dr Adequate
