Why do East Asians have BIGGER brains than Europeans or Africans?

[HannibalBarca]

The reason is simple, we have to compensate with the size of our second brain... We took some from the top to give to the bottom one... or vice versa...

I think poster already knows the reason why East asian brains are bigger and what are the traits that comes with it.

The true question is why did mother nature decided that East Asians needed to have bigger brains in the first place?

Was it their surroundings and the conditions that they've lived in that necessitated the larger brain size, to bring about adaptatory benefits that comes with the increased brainpower- along with the sacrificial negative traits such as high frequencies of idiopathic/congenital myopia and generally-reduced body mass.
