Reply to comment by herbw in TIL that most non-human primate infants actively use their hands to help themselves out of the birth canal. Human infants do not, but their grip strength is much higher during the hours immediately after they are born. by afeeney

It's amazing really. When you compare the size of a baby's head to an adult it's incredible how much their brain develops. It makes a lot of sense that the newborn is sort of an instinctual primate from the beginning and then through nutrition and nurture becomes a human being.

Considering that brain can use about 20% of both circulation and foods, it's not at all unusual.

All thanks to agriculture (or if further back, the hunter-gatherer beginnings of man)

I heard also that two legged and furless results in less consumption of nutrition.
