Humans living at high latitude have bigger eyes and bigger brains to cope with poor light during long winters and cloudy days, UK scientists have said.
The Oxford University team said bigger brains did not make people smarter.
Larger vision processing areas fill the extra capacity, they write in the Royal Society's Biology Letters journal.
The scientists measured the eye sockets and brain volumes of 55 skulls from 12 populations across the world, and plotted the results against latitude.
Lead author Eiluned Pearce told BBC News: "We found a positive relationship between absolute latitude and both eye socket size and cranial capacity." - BBC
Why should this be taboo?
Why are we so squeamish about evolution?
Why not instead ban central heating and send everyone into the arctic circle?
