Doctors have hoped human infants would relearn this trait that apparently got lost to evolution, as it would aid the birthing process mightily. Same reason that pregnant women in Cambodia are occasionally killed for their unborn fetus.

You don't even need to train your grip strength as an infant. Have you seen infant gains? It's like half a kilo a month.
Applejuiceinthehall t1_ivbi7ca wrote
Actually, humans have the second longest gestation than other great apes adjusted for size.
The skull size ratio for baby humans is 30% of adult size. For chimps, it's 40% of adult size. So, for humans, that would be about the size at 3 months. There are already women who have hip width that can accommodate that.
Additionally, when studying the gait, wider hips do not make women worse walkers/runners.
So it's probably not that babies came out to accommodate women, but that started being born early for another reason and women's hips width is that size because of baby
Frequent-Seaweed4 t1_ivbpm2i wrote
We suspect babies started being born earlier because while some women can accomodate a child with chimp-birth requirement, many can't, and this is a population genetics question, not a mendelian genetics question.

Part of the problem. A big brain can take up a lot of space for a live birthing organism. Imagine the head of a baby at 3 months being pushed through the coochie

Not just that, but calories - the brain takes up a huge chunk of calories during infancy, massively slowing development, requiring more calories and making kids more vulnerable to famine

Yeah, but if there was a huge advantage like skipping three months of potato-like infancy, women would shift rapidly genetically. That isn’t a barrier if it already exists in the population

Most non-human primates are also significantly more physically developed at birth. Human infants are born underdeveloped because our brains are so big that staying in the womb any longer would make it impossible for us to even make it out of the birth canal.

That was the idea, but it doesn't pan out when you look at the evidence. Some women can already accommodate that size skull. So if babies were born with a 3 month olds skull, then the selective pressure would be for wider hips.
Because of women with wider hips, we know that their walking/running isn't impeded with wider hips.

I was genuinely surprised when my newborn daughter gripped my finger for the first time. It was a really strong grip. And it’s funny because they won’t let go, and it’s not that easy to make them let go. They only learn to let go off objects in the first 3-4 months.

I you put your finger on the sole of a baby's foot the toes will instinctively try to grasp it, like a monkey. Incredibly cute but also fascinating.
herbw t1_ivce90j wrote
Most peds specialists know of the grasp reflex of infants. We simply stroke their palms and they close thie fingers around our finger. It's a primitive reflex likely due to holdin onto Mom tightly enough not to fall. Most primate infants also have that.
When people get older and get senile, the grasp reflex re-emerges, as a sign of dementia. Bidie likely has it; and the Glabellar, meaning when you tell him not to blink, and tap the skin between the eyebrows over the nose, he will NOT be able to stop blinking.
Did that to my f. in law, and he blinked. I kept quiet about it. Then they began to cause me trouble and reported that.
Ya don't PO a medical professional. We have life, health and prognostic deep knowledge. and we know how to use it.
So wisdom to the sophomoric persons round here.

I know of a person who had to have an emergency C-section because their baby grabbed into its cord during birth and was suffocating itself. The doctor just shook their head because they thought the kid would let go when they started de-satting, but nope. That's a strong reflex!
Applejuiceinthehall t1_ivceqf5 wrote
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
herbw t1_ivcf1u6 wrote
Yes, babies have a stepping out reflex from very early on. We find that by holding them up, legs and feet down, and then moving them forward. Often we see 1 leg moving forward and then the next, and then back & forth. But hafta do it right.

Human reproduction is complex system. The pelves of PG woman will expand due to a substance which causes the cartilage of the pelvic bones to relax, so the birth canal widens. to allow easier deliveries. When a pelvis of a woman who has given birth to a child/children is found we can see that on post mortem. How we know it.
Gestating babies, and delivering them is very complex system & has many, many interesting events going on, too.

Nah, the bottleneck (heh) is the amount of energy a baby needs to survive within the womb. Birth happens when the placenta's throughput isn't enough to sustain the baby much longer, and it triggers the delivery process.
Kinda wonky to think that boobs are able to push much more nutrients through them than the placenta itself. Anywhere between 500-700kcals, that's as much as the brain itself uses and it's the most energy-intensive organ in the human body.

Lastly, and with all the respect you are due, which incidentally is precisely none…
I have no problem handling reality. I knows births happen, I have no difficulty accepting that. I celebrate births when done by people I know, and I find great joy in watching the resulting humans develop and grow into intelligent, capable adults. I personally merely find the prospect of birthing intensely and viscerally unappealing. So I take steps to ensure, to the best of my ability, that it’s a situation I never find myself in, while maintaining the utmost respect and admiration for those who do.
