Damn son our uterus stretches like 5x the size and then contracts and pushes a 7 pound baby out of a small tube into life if you think that isn’t metal as fuck get out of my face
YOUR ORGANS THOUGH IM SO SORRY LADIES
How the hell do woman survive this?
Seriously it surprises me how many people don’t know a couple things about pregnancy and babies:
women would not survive 10 months of pregnancy they would die
A baby is nowhere near as developed as it should be to be out in the world at 9 months, but the human body has not evolved to push anything past the size of the head out, everything else the baby is can stretch and squash but the head
the vagina can’t handle anything bigger than the head at 9 months of development so we have to give birth.
But babies actually need longer than that, really, it’s why they’re such a mess when they’re born and why they’re completely dependent on care, can’t walk, can’t do anything. Note most other animals can when they are born. Babies are born too early, it’s kind of a huge and secret flaw in human evolution. I found it really interesting, so thought I’d share.
why is this transparent
My mom was just about a week short of 10 months pregnant with me by the time I came out (I like to think I was hanging on to the umbilical cord, trying to keep from entering this world). She lived. No C-section — she pushed me out even though I was one big baby by then. Doctors wouldn’t allow a pregnancy to go that long these days, but 39 years ago it was a different story.
As for the rest, well, I’m no expert. My only experience with babies is when I was one, and that was a long time ago, and my memory of that time is pretty hazy to say the least. I wouldn’t argue this post at all, because I’m a bit out of my element on this one. But I was asked to take it on, so I’ll just present another theory, put forward in 2012 (source 1) (source 2) (source 3):
While it’s true that the mother probably couldn’t handle a longer gestation, it’s not because the baby would be too big to push out and babies aren’t being born “too early.” The extra time for the baby’s brain to develop more would require an extra 3cm (1.18 inches) of room, which a woman could pull off if needed.
Instead, it has to do with the mother’s metabolism. Anthropologist Herman Ponzer says, “There is a limit to the number of calories our bodies can burn each day. During pregnancy, women approach that energetic ceiling and give birth right before they reach it. That suggests there is an energetic limit to human gestation length and fetal growth.”
The baby has to be born because the mother will no longer be able to provide enough energy to support it, not because of it getting too large to be delivered.
Evolutionary biologist John Fleagle thinks that human babies being born helpless isn’t a bad thing. It gives them more experience to learn from after being born.
