Reply to comment by Frequent-Seaweed4 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
But it's only the average because human babies don't have skulls that are 40% of adult skull (which chimps have). If humans were born with that big of skull then women with wider hips would have been selected for and women with narrow hips would have been filtered out
