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

When I was a kid still grappling with the whole religion thing, I just took it as the vibe being a set of parables to learn from. If a god exists, it's through the invisible visible sciences of physics, evolution and all that fun stuff.

Yes, precisely that a species with so much paradoxical feature like human should not exist. If human acquire bipedal first, then it should heavily select against big brain according to natural selection theory. But since natural selection pretty much attribute everything to randomness, the theory practically unfalsifiable.

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.

with all due respect, birthing is a reality of billions of years, and billions of events/year. . if you can't handle reality, then there's a problem.
miasabine t1_ivgcrpb wrote
Birthing humans have only been around for a couple hundred thousand years, and something being reality doesn’t preclude it from being a phobia. If that were the case, there would be no phobias. Pregnancy and birth still kills thousands upon thousands of women every single year, and leaves many others with chronic pain, PTSD, and various disabilities. 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.
If you think that’s a “problem” in any sense of the word, you’re more than welcome to your opinion. However absurd and pathetic it might be.

Fine, then yer cherry picking the data. Violation of the comprensiveness rule. Modern humans are about 100K yrs old, or so. The data in east AFrica bone finds show that, very likely.

Our cortical cell columns are better than erectus. Closer to cro-magnon. Nor has human evolution stopped. Our continuing techno capabilities shows that. Follow tools making from the stone age, to present tech. Humans are getting smarter. That's been going on for 100K's of years in us and our ancestors. Our cortical cell columns, where the info processin goes on, are more efficient and more of them than our ancestors, even 10K yrs. ago.
How do our brains create information? Why has THAT question not been widely asked? Answering that deep question shows how, the brain processors create creativities. Where creativity likely comes from in brain. Structure/function general model in biology, and most tech, t00 Here's now it's done.

forbes is not an anthropological mag. OK?
Modern humans arose about 100-125K yrs ago in east africa. before that it was H. erectus which is NOT modern man. OK, they are considered in the Homo Genus with modern humans. That's the big error they are committin there.
Homo neanderthalensis would be modern human by their criteria those been extinct for 10K's of years.
It's basic biology. H. sapiens sapiens. Forbes does NOT make the clear use biological definition clear, either
Humans with our high social forms and intellectual characsteristics are about 10-20K yrs old. but as we cannot tell intellectual linguistic prowess but by stone age tools and bones, we estimate the first humans most like us, physically, came about 100-125K yrs ago. Cro-magnan is older than we too, but a side chain as well.
It's anthropology, NOT Forbes business news specialty, either.

It's amazing really. When you compare the size of a baby's head to an adult it's incredible how much their brain develops. It makes a lot of sense that the newborn is sort of an instinctual primate from the beginning and then through nutrition and nurture becomes a human being.

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.

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
Applejuiceinthehall t1_ivc8ydl wrote
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.
Frequent-Seaweed4 t1_ivcb6wr wrote
Okay but you keep saying "some" women, when we're talking about the "average" woman.
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_ivcftpy wrote
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.

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.
