"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 scientists measured the eye sockets and brain volumes of 55 skulls from 12 populations across the world, and plotted the results against latitude.
The largest brain cavities came from Scandinavia, while the smallest were from Micronesia."

"What is the use of living, if it be not to strive for noble causes and to make this muddled world a better place for those who will live in it after we are gone?", Winston Churchill.
This one is really funny:
The Oxford University team said bigger brains did not make people smarter.
The Sperm Whale has an enormous brain (9kg).
They must be really smart.
well, according to national IQ's, Spain or Italy have higher than Norway, Finland or Denmark
Yeah if you look at the study, eye size is definitively correlated with latitude, but brain size really isn't.
Brain sized shows a peak sample at 37 degrees latitude. It does show a trend from smaller brains to bigger going into higher latitudes, but most Europeans 35 degrees or higher, showed similar results.
Eye size did peak at the higher latitude and showed a much stronger correlation with latitude.
What this shows is that brain size is more correlated with 37+ degrees of latitude than with higher latitudes which shows a divergence amongst North African and Subsaharan African brain size in comparison to Europeans.
It also does show a fair correlation with eye size and latitude. But again, lower latitude Europeans did not fit well with the correlation.
neanderthals also had larger brains than the Cromagnon. So what?
If you may realized, many Asians too live in High Altitude (Mount Everest is in Asia). But if you look at their eyes...... and as they say that people in High Altitude have bigger eye socket and all....
Its just a theory....
But its true that a Polar Bear has a bigger brain than Grizzly. But Grizzly is said to be as smarter as Polar Bear due to its heavy diet on fishes. Fishes have omega 3 fats which is good for the brain.
A similar study in a University in France(maybe Lyon, I'm not sure) ensued the immediate dismissal of the said professors from their job positions. The study was about how black skinned Africans were less prone to creating a rich civilization due to their scale of evolution. Needless to say, those men knew nothing of history of art in Africa, nothing at all. However, I do find the trend for creating such so-called studies very alarming.
