Ok, I had to dog out my book to recall just what about the Antarctica theory made me roll my eyes. Hitchcock had been proposing some dramatic continental displacement of Antarctica almost instantaneously. (last year’s Japanese earthquake did move Japan by a couple of meters.)
I am willing to accept that something may have gone on in Antarctica, but I do not know where it fit in Pangea, or what its state was during the Ice Age. My gut feel is that modern humans do date to within a couple hundred thousand years, so the continents would have generally been where they are now.
Hitchcock starts the book describing old Venetian maps that show Antarctica’s coastline......without ice, and the maps are generally correct, as modern technology can map the coastline without the ice covering. The hypothesis was that at some point, Antarctica was without the ice, and those sections of maps were copied and recopied through long stretches of time. Definitely one of those things that makes you go hmmmmmmmm.
Am aware of the wandering Antartica you mentioned before it wound up where it is presently at which was after “the great split” . I believe that was prior to the 2nd last ice over, around 40-50,000 years ago .
