because ye jaruri nhi h ki agar brain ka size bada h to us animal ka IQ power bhi jyada ho, humans ka IQ level sabse jyada h is earth par, that's why humans ne fire ki discovery ki.

Answer 2

As it turns out, there is a simple explanation for how the human brain, and it alone, can be at the same time similar to others in its evolutionary constraints, and yet so different to the point of endowing us with the ability to ponder our own material and metaphysical origins. First, we are primates, and this bestows upon humans the advantage of a large number of neurons packed into a small cerebral cortex. And second, thanks to a technological innovation introduced by our ancestors, we escaped the energetic constraint that limits all other animals to the smaller number of cortical neurons that can be afforded by a raw diet in the wild.
