But how much (and what bits) of brain architecture is devoted to those higher functions (versus supporting what we might call 'intelligent behavior' of animals having to survive in the real world)?

Yes, most animals didnt evolve language. But language evolved in a blink, ~200Kyrs (or 1Myrs, if you think Neanderthal and Denisovan had language). And population sizes were small, and generations long, which suggests it's a very easy evolutionary step for apes to get language.
- it’s not that easy or more primates would be talking; the adaptive advantage is likely huge - but yes the only way to evolve language quick is to already have a genome packed chock full of innate tools that are good for cognition. that was key point of The Birth of the Mind

So, then what are those elements of cognition that brains have that AI doesn't? Is it the architecture for predictive processing? Is it that they incorporate value and meaning through experience?
-
Is it recursive communication between multiple levels of the cortical hierarchy? Or will we need AI to have an equivalent of a hippocampus and a thalamus and a striatum?

Indeed, the adaptive advantage of language is enormous. As demonstrated by the fact that about 99.999% of primates on this planet have the innate potential for language.

And growing... (rapidly)
