View Full Version : Northerners Have Bigger Brains And Eye Sockets According To Science Researchers At Oxford University

Scientists at Oxford University in England have found that people in northern latitudes have evolved to have larger brains and eye sockets, and have more grey matter in the brain, due to the lower levels of sunlight in northern hemisphere.

Now before people get big-headed about this; 'Having bigger brains doesn’t mean that higher latitude humans are smarter, it just means they need bigger brains to be able to see well where they live.’

Is that true for Eskimos too, or just northern Europeans?

I'd guess so, since they live in a region with low sunlight levels.

I would guess not, since their accomplishments come nothing close to northern Europeans.

This is not about peoples intelligence or the quality or health condition of peoples brains; :rolleyes: this is simply about brain and eye socket sizes.

More grey matter just to "see better"? Why, did northerners hunt animals several hundred meters away (with what?) or did they hunt microorganisms?

Most of your post. What are you saying about hunting large animals?

Completely the opposite. I was wondering whether evolution favored better vision in northerners because they had to hunt animals from either far away, or very very small animals.

Aha, I see.

Well, most humans hunt primarily small animals. The only human group which exclusively or almost exclusively hunts large animals is the Inuit because they are the only group to live in an environment where most food is in large animal form (pre-Inuit people like the Dorset Culture and Sadlermuit would also qualify, but keeping it simple). The reason humans hunt medium sized animals is because that's the safest route that actually leaves us with something worth eating at the end. Ergo, Northerners did not hunt smaller animals than Southerners.

As for hunting animals from far away; I doubt there'd be much variation within Great Britain.

Actually my question to English Rose was sarcastic, because she face palmed my inability to understand that bigger brains had nothing to do with intelligence and everything to do with better vision.

Your brain is the fattest organ in your body. It's about 60% fat.

Scientists Say Dieting Causes Your Brain To Eat Itself. Now, the body cannibalizing itself isn’t something new, when the body is starving cells will start consuming pieces of themselves in a process known as autophagy, but until now, it was believed that the brain was resistant to this process.

Big Brains Cause Cramped Mouths: Evolution isn't perfect. If it were, we might have wings instead of wisdom teeth. Sometimes useless features stick around in a species simply because they're not doing much harm. But wisdom teeth weren't always a cash crop for oral surgeons. Long ago, they served as a useful third set of meat-mashing molars. But as our brains grew our jawbone structure changed, leaving us with expensively overcrowded mouths.

Your brain is made up of about 75 percent water.

Your brain consists of about 100 billion neurons.

You have over 100,000 miles of axons in your brain. They could wrap around the Earth 4 times.

At birth, your brain was almost the same size as an adult brain and contained most of the brain cells for your whole life.

You had more brain cells when you were 2 years-old than you will at any other point in your life.

Frequent dreams are correlated with having a higher IQ.

Ancient peoples thought the brain wasn’t important as the stomach and heart. When mummifying people, Egyptians would pull the brain out through the nose.

Having a bigger brain doesn’t make you smarter. In fact, Albert Einstein had a relatively small brain.
