This study was included in Foister at al.(2023):

https://onlinelibrary.wiley.com/doi/full/10.1002/evan.22005

Overall it shows that wetland was a small proportion of environments of
early Pleistocene Homo (see fig.2).

Be a luv? Could you post some cites on early Pleistocene
Chimpanzee finds? Thanks ever so much.

Smooches!

The point, of course, is that there are no Chimp finds.

None.

Zip, zero & nil.

So we don't have anything even remotely similar to a
comprehensive study of early Pleistocene environments.
We don't have anything that could be mistaken as such,
even if you squint. UNLESS, the interpretation of the
fossil record is complete hogwash.

Kind of a Catch-22 there, wouldn't you say?
