Pleistocene archaic Homo regularly dived for shellfish:
8 independent indications Indonesian early-Pleist.H.erectus dived for shellfish:
•Archaic Homo's tooth-wear was caused by "sand & oral processing of marine mollusks", Towle cs 2022 https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24500
•H.erectus s.s. fossilized (always?) in coastal sediments, e.g. Mojokerto amid barnacles & corals, Trinil amid edible Pseudodon & Elongaria, Sangiran-17 in "brackish marsh near the coast".
•Stephen Munro discovered sea-shell engravings made by H.erectus: José Joordens cs 2015 Nature 518:228–231 https://pubmed.ncbi.nlm.nih.gov/25470048/
•Ear exostoses (bony outgrowths of the ear-canal in H.erectus & H.neand.) develop after years of cold(er) water irrigation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696936/
•Pachy-osteo-sclerosis is typically & exclusively seen in slow+shallow-diving tetrapods (de Buffrénil cs 2010 J.Mamm.Evol.17:101-120), e.g. erectus’ parietal bone is 2x as thick as in gorillas.
•Brain size in erectus (2x apes-australopiths) is facilitated by sea-food, e.g. DHA etc. in shellfish, cf Odontocetes & Pinnipedia.
•Pleistocene Homo even colonized overseas islands (Flores & later even Luzon) https://www.academia.edu/36193382/Coastal_Dispersal_of_Pleistocene_Homo_2018
•Homo’s stone tool use & dexterity is typical for shellfish-eaters, e.g. sea-otters etc.

If I'm allowed to be contradictory...

#1.
The Pleistocene is fake. It's literally the Quaternary period
with the Holocene removed for no discernible reason.

The Holocene is NOT distinct.

#2.

I'm certain that the exploitation of marine resources began
long before the Pleistocene. This likely included diving, at
least on occasion.

#3.

I'm certain at this point that the greater part of Homo
evolution did not take place in a linear fashion but,
concurrently.

The "Distributed Computing" model...

There were populations on the coast. There were
populations inland. They met. They interbred.

Over time Homo coalesced. Homo wasn't "Replaced"
but coalesced.

homogenized.

Otherwise you got everything exactly right. Well.
Except for anything else I disagree with.

Fine, I'm no geologist, but this is not contradictory AFAICS?

Yes, likely, but we have no Pliocene Homo s.s. fossils AFAIK.
IOW, not contradictory AFAICS.

Not impossible, but so far impossible to prove AFAICS.
What seems to be clear: early-Pleist./Quaternary H.erectus in ISEA regularly dived for shellfish.
IMO, their Pliocene ancestors must have followed the N-Ind.Ocean coasts.

:-) Excellent.
