And plenty of people smarter than you have debunked the notion that the size of the birth canal historically was significant to the size of brains, since most children experience most of their size increase after being born. That more children are saved via c-sections because they’re larger from earlier development or because they’re just relatively larger than their mother isn’t statistically significant for brain size or the practical results of that increase.
This has been covered in other replies and it’s obvious you’re being obtuse about it, so I’m ending the conversation from my end here. Enjoy arguing with someone else about it.
