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.
In short, that’s completely ridiculous. It’s not a “flaw in human evolution”! There’s this thing called precocial vs. altritial young. Snakes, for example, guinea pigs, and deer (most, if not all, hoofstock, in fact) are born/hatched precocial, or relatively ready to face the world. Humans, kittens, most (if not all) birds, puppies, mice, and rats are born altritial, meaning that they require intensive care and raising by the parents and are otherwise incapable of surviving on their own until they mature. Now, this is obviously a spectrum sort of thing where some precocial species are definitely more ready than others (snakes receive little to no parental care, whereas antelope calves need to stay with the mother for a period), and some altritial species are born more formed and ready than others. The basic idea is that precocial young need to be able to evade predators from the day that they’re born.
I’m not an ecologist or developmental biologist, but I DO know that animals’ (that includes humans) pregnancy and young nurturing periods are a precisely timed balancing act of maternal nutrition, risks after birth, and available nutrition after birth. If you notice, many prey-type species are born precocial because they need to develop quickly and be ready to move with the herd shortly after birth. Predators, on the other hand, tend to have altritial young. The young are at lower risk of predation and the parents can leave their young behind while they hunt with relatively lower risk. It’s a cost vs. benefits balance with the eternal goal of reaching each species’ optimal reproductive conditions and maximize survivability. Humans are broken in many ways, but on this front, we’re right on par for our species and current position in the animal kingdom (though some would argue for a lack thereof). The cost to the mother to birth more developed babies is not equivalent to the risk human young face at birth. It wouldn’t make sense, evolutionarily speaking.
