human physiology & anatomy leave 0 doubt that our ancestors regularly dived, most likely often for shellfish, probably maximally early-Pleistocene,

Oh, of course. Don't waste your time on that...
What I believe -- and I'm right, of course -- is that the originally theorized
"Aquatic Phase" followed by a return to inland survival, before moving
BACK to Aquatic Ape and finishing inland is wrong.
Yes, evolution is no straight line: it depends on the environment (sometimes abrupt changes, e.g. the opening of the Red Sea into the Gulf).
But our reconstructions have to be based on facts: the more details we know, the finer our reconstructions. And often: the longer ago, the less we know.
So far, we can say a lot more than what Hardy or Elaine knew, but there are still a lot of unknowns.
I wouldn't go much farther today than:
- Miocene aquarboreal adaptations,
- early-Pleistocene diving adaptations,
- mid-late-Pleist. -> wading -> walking.
That's linear.. "Well they were THIS and then they were THAT."
I hate linear models. They seem to occur extremely rarely in nature, and
we are speaking of a period of MILLIONS of years spanning a number of
species and even more than one genus. There seems little chance that
a linear model can work, and when I say "Little" I mean "None at all." Savanna idiocy is one huge linear model: They fell out of a tree, landed on
a savanna and ran after antelope, only stopping when they reached
Australia.
Yes, every sensible human agrees: the savanna nonsense is just nonsense. :-DDD
