Researchers Say Dark Winters Led To Bigger Human Brains
Brad1138 writes "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. from the article: '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."'"
Your comment just suggests you didn't bother to RTFA.
"In the paper, we argue that having bigger brains doesn't mean that high-latitude humans are necessarily smarter. It's just they need bigger eyes and brains to be able to see well where they live."
They're saying that the extra cranial capacity is being used by the visual processing centres of the brain.
And to be honest, your comment isn't combating racism, it's reinforcing it.

Not sure what statistical model they used, but there are plenty that allow for small sample sizes when certain conditions are met. Check out http://en.wikipedia.org/wiki/Student's_t-test
