At some point Dr Algis Kuliukas mentions the Wallace
Line, and asks why didn't Homo or some pre Homo
ancestor (or whatever) get across it. And I've got to
ask:

Who says they didn't?

It's not like distribution would have been random. Those
enormous valleys that used to exist? THAT'S where they
would've wanted to live.

Google some pictures of the Australian Outback. Whatever
group first arrived, they weren't traveling across AND LIVING
IN such an environment. And they certainly weren't in any
rush to leave the life they knew behind to push inland and
learn how to live all over again.

Nope.

They were living in those valleys. Then when the next
interglacial hit they were pushed out, pushed inland...

They were likely pushed even further by new arrivals.

THE POINT IS that if they had crossed the Wallace Line
they were living where today there is only ocean. So if we
want to find them, we have to be looking under the sea.

Whether they crossed the Wallace-Line or not is not so important IMO.
(I thought Flores, where H.floresiensis was found, was E of the Wallace-Line?) Algis (google "WHATtalk") lives in Australia, he promotes the vision that our ancestors were predom.wading.
Not impossible IMO, but pachyosteosclerosis in H.erectus leaves 0 doubt: they often dived.
