> However, as someone who studies intelligence, I would say that because of modern nutrition, medicine, evolution, and adaptation, modern humans are probably a tiny bit more intelligent than ancient humans. I would guess that someone alive 50,000 years ago who was transported to today and raised as a modern human would have little trouble, but that the average ancient human would probably be slightly less intelligent than the average modern human.

Modern humans allegedly have slightly smaller brains than humans 3000 years ago. https://www.bbc.com/future/article/20220503-why-human-brains...

There's also the question of what we are actually measuring when we talk about "intelligence". It seems this is at least somewhat culturally subjective. This means that while you might be technically correct, people 50000 years ago might value aspects of intelligence that is slightly different, and they may excel in those aspects instead.

In general, I don't know whether there can be any meaningful conclusion on whether "culture" advances. To me culture is always a matter of gaining a focus on one aspect and losing focus on another at the same time. I.e. a matter of preference and taste. Is there really something as "better" taste in general? Yes if you impose your subjective views onto to others, and no if you are fundamentally egalitarian or relativist. But then if you measure specifics (eg. how life-like/realistic were the paintings? How harmonious were the music?) you'll get some trends. The problem is that those trends aren't necessarily "improvement" if those aspects are subjectively considered a negative trait.
