    Smarter Brains Are Blood-Thirsty Brains.

    Smarter Brains Are Blood-Thirsty Brains.

    Attachment 11315

    A University of Adelaide-led project has overturned the theory that the evolution of human intelligence was simply related to the size of the brain -- but rather linked more closely to the supply of blood to the brain.

    I think the idea that brain-size correlates to intelligence has been discredited for a long time now.

    The small brain society backs this conclusion.

    I think you may be wrong about that.

    Recent research suggests that intelligence is more related to how the brain is 'wired' or the way that synapses are organised - as well as blood supply etc. The idea that brain size correlates to intelligence in mammals and humans is an older idea and newer studies seem to be going the other way.

    Albert Einstein's brain weighed less than average. His difference were extra glial cells which make up 90% of the brain. A type of glial cell called the astrocyte located in the cortex, may be where brain power and creativity reside. Einstein had the ability to visualize his mathematical thoughts. He also had many more connections between hemispheres.

    Size in Einstein's case didn't matter. It was the proportion of ingredients and structure. By the way Einstein is an honorary member of the small brain society.

    Nine out of ten Neanderthal intellectuals agree that size doesn't matter.

    Ha! I first took the thread title, Smarter Brains Are Blood-Thirsty Brains, another way - Blood-Thirsty predators being smarter than poor Bambi, which tends to be true. And as we've become smarter we certainly have become better at spilling more and more blood.
    Estimated ancestry drawing on Living DNA and family history:
    English 36%, Scottish 24%, Irish 17%, Welsh 16%, German 4.5%, Scandinavian 1.3%, Netherlands 0.6%, French 0.6%

    Y-DNA leads to Isle of Skye then to Isle of Lewis, Scottish Highlands: R1b > M343 > L278 > L754 > L389 > P297 > M269 > L23 > L51 > L151/L11 > P312 > Z290 > L21/M529 > DF13 > L513/DF1 > S5668 > A7 > Z21253 > S7834 > S7828 > BY11203 > BY11186 (about 320-550 years old)
