When young, 50 yrs ago, were old wives tales, with things untrue. ie: don't hang curtains while you're pregnant or you'll wrap the baby's cord around its neck. Don't eat certain foods or the baby would have a birthmark. To rely on this is dangerous. Same for this poo of Elon. I'd trust a doc!
It's not a theory. Phrenology (the idea that skull size correlates with anything at all) was disproved ages ago, and is regarded as pseudoscience, ie a lie.
Because it's a hypothesis that equates brain size with intelligence.
If it doesn't, then what the fuck difference does head size make? Is it those red caps that only come in very small sizes?
Like I said he doesn't have to, it's the only possible interpretation that means Anything-at-all!.. Unless suddenly hat sizes are important. Otherwise it's a completely meaningless observation. Imagine if it said hand size instead. Who would care?
He’s maybe onto something that Musk fella … here’s how he reckons we should all look once his mandatory c-section orders are carried out for a few years .. just think how many electric cars you could build with workforce of these guys !! And maybe less of them would burst into flames ??
I wasn't even aware people connected him TO Paypal until like...literally this calendar year. It was made by the people behind eBay, wasn't it? That's what I'd always heard.
So Elon, to carry the analogy further, your an asshole because you were dropped on the floor multiple times during birth. Something I heard about being a very slimy baby
I'm NOT a pediatrician, and even I can tell it's a lie. What's next? Brain size indicates intelligence, or only white people have large brains ... therefore ... more BS.
Omg he is correct in saying he has a mental disability that limits his thoughts process. I can't believe that dimwit actually believes this c section ca ca.
Now Elon is claiming to know more about birth happening by a women then a paediatrician.
When Elon can drop a baby from his man hole he can speak about woman having a baby. Till then he needs to keep his fucken mouth shut.
Guy probably thinks c-sections are super safe and easy or something. As if bisecting a woman's entire fucking abdomen is just a quick and easy fix with no risk of permanent impairment to the womb or to the mother's health.
Stitching dozens of blood vessels back together in the uterine wall and all 7 abdominal layers? Stitching each individual muscle back together? What? But in the movies they just sew the skin and it all works out?
Does he think voluntary c-sections will trigger an evolutionary event that will increase the head circumference?!? If so, why hasn't removing permanent teeth not triggered the growth of a new set?
The birth canal *does* put a practical constraint on head/brain size. Removing that constraint over many, many generations might increase the average human brain size (assuming it were a reproductive advantage, which it might not be).
But that’s just part of the process. The baby is designed to come out of the vagina. That’s why the head molds to get out, you’re not gonna change that by never having another vaginal birth. ..oh, and not for nothing, babies all have different head sizes and even big head babies get out.
The birth canal does constrain brain size (obstetric selection), but evolution is more complex than that. Widespread C-sections alone wouldn’t immediately lead to bigger brains, but might after many generations and a reproductive advantage. Skull molding and other factors also play a role.
Okay, but here’s the thing. The baby’s head isn’t being prepared for a c-section, it’s being prepared for a vaginal birth. There’s no way to make the baby grow larger because it’ll be coming out via c-section. I hope that makes sense
Right, it’s not that babies’ heads will grow larger specifically for a c-section, it’s that over many (many many many) generations, more larger-headed babies that wouldn’t have otherwise been born safely will now survive and pass on their larger-headed genes.
Of course it’s complicated though. As you mentioned, babies with traditionally dangerously big heads are often delivered safely via c-section, so their genes are mostly getting into the gene pool already. And the birth canal isn’t the *only* factor limiting head size, there are others.

It's as if you think of Phrenology as a disputed science!
And shouldn't a doctor know the difference?
I heard this theory decades ago.
Yeah, Elon is still a dipshit.
If it doesn't, then what the fuck difference does head size make? Is it those red caps that only come in very small sizes?
"I imagine I know EVERYTHING ABOUT EVERYTHING..."
Elon mum.
Wake up: waking reality that Elon is an actual predatory alien
Ya can't explain that
Musk is a danger to every living person
