This is weak, to say the least, and easily countered by pointing to the scorching sun in a desert and droughts(according to your logic, Somalians should be the smartest people on earth).

There is very little evidence that humans have evolved our cognitive abilities since our change in diet(more meat) around 50.000 years ago. No surprises there, given that evolution is an extremely slow process.

As for your drivel on adopted children, it's needless to say it's not supported by science.
In any case, the human brain, unlike the octopus one which is supposed to have evolved to devise ways of finding food and avoid becoming food, is geared towards social interaction, like most other advanced brains in the animal kingdom. So better use of the brain is achieved by exposing the individual to greater social stimulation. Which is culture, not genetics.
