AFAWK there has been no significant change in the anatomy of humans in the past 200k years, and similarly nothing to indicate that we’ve had major changes in things like our ability to abstract. The bicameral theory of mind has been thoroughly discredited.
If you can show me the tomb of a prominent world leader from the last, let's say, 500 years that's decorated with images of his/her enemies' severed genitalia, I'll concede the point.
Generally every theory which talks about these great leaps in human cognition, and ties these to human "development" while ascribing diminished intellectual capabilities to our ancestors, seems to fall apart after scrutiny (e.g., Sapir-Whorf hypothesis, bicameral theory of mind).
Also, we've seen plenty of "undoing" of abstraction in long-continuing cultures. E.g., in Hinduism, idol worship wasn't really a thing in Vedic times, and only became popular in Puranic times (over a 1000 years later). Many Hindus do believe that some idols contain portions of gods, especially those idols that reside ones in "big" temples. I would not say that these folks have lost their ability to abstract. As another example, post-Vedic religion underwent a large amount of abstraction in the Upanishads, but then reverted to personification of deities via the bhakti movement and in Puranic religion. Again, I wouldn't say that Hindus lost their ability to think abstractly.
Isn’t something like this the general explanation for the Flynn effect? (that newer generations in modern societies are better at IQ tests because they’re better at IQ test-style abstractions)
I get the impression that the degree to which people took religion literally varied a lot from person to person, and even priest to priest throughout history.
It’s not clear whether more people took religious belief literally, or if they just said they did for political and social reasons.
Sure it claims way too much, but I don’t think every nearby direction is discredited. That would mean everyone in history had the exact same theory of unitary consciousness we do (that we have free will, our actions come after conscious thought, there’s a conscious/subconscious/unconscious or id/ego/superego, dreams come from our own memories, etc.)
There’s a lot of Buddhists out there to this day, and they do officially belong to a religion with a you-don’t-exist policy. How this is integrated with resurrection depends on the lineage of course.
Myself I just want to know if the Babylonians were taught math by a fish alien named Oannes. Maybe he can tell us if P=NP.

Most of the recent academic work I'm familiar with tends to emphasize the opposite case, tempered by the fact that ancient religion and culture tend to be very alien. Take, for instance, popular reviews by Irving Finkel in his "Noah" book, or Ed Barnhart's work on the Moche, etc.
But, I read about the piles of genitalia in Toby Wilkinson's "The Rise and Fall of Ancient Egypt" and about the god-statues in Trevor Bryce's "Babylonia: A Very Short Introduction."
There aren’t streets, rather everyone supposedly traveled on top of everyone else’s roofs. There were family homes but not public buildings. And they buried their dead family members right inside their own houses and sometimes kept their skulls out for decoration.
