alt Hacker News> A caveman from 200K years ago would have been just as intelligent as any of us here today, despite not having language or technology, or any knowledge.
Doubt. If we would teleport cavemen babies right out of the womb to our times, I don't think they'd turn into high IQ individuals. People knowledgeable on human history / human evolution might now the correct answer.

Its complicated. It depends.
A human being has the potential for intelligence. For that to get realized, you need circumstances, you need culture aka "societal" software and the resources to suspend the grind of work in formative years and allow for the speed-running of the process of knowledge preloading before the brain gets stable.
The parents then must support this endeavor under sacrifices.
There is also a ton of chicken-egg catch22s buried in this whole thing.
If the society is not rich then no school, instead childlabour. If child-labour society is pre-industrial ineffective and thus, no riches to support and redistribute.
Also is your societies culture root-hardened. Means - on a collapse of complexity in bad times, can it recover even powering through the usual "redistribute the nuts and bolts from the bakery" sentiments rampant in bad times. Can it stay organize and organize centralizing of funds for new endeavors. Organizing a sailing ship in a medieval society, means in every village 1 person starves to death. Can your society accomplish that without riots?
Thus.
Can you articulate why you think so? This kind of response "I just don't agree" reads as zero useful information. At least to me.
From what I understand, in terms of genetic changes to intellectual abilities, there's not much evidence to suggest we're so much smarter that your proposed teleported baby would be noticeably stupider - at best they'd be on the tail of the bell curve, well within a normal distribution. Maybe if we teleported ten thousand babies, their bell curve would be slightly behind ours. Take a look at "wild children" for the very few examples we can find of modern humans developed without culture. Seems like above everything, our culture, society, and thus education is what makes us smart. And our incredibly high calorie food, of course.
It is known that 200k years ago human brain sizes were actually greater than today, even if this does not necessarily correlate with a lower IQ in the present, because it is more likely that the parts of the brain that have reduced may have been related with things like fine motor skills and spatial orientation, which are no longer important today for most people.
