I've seen NO after the flood, and I really doubt that anyone will 'adapt' to live in what's there now; but will move to a location that is very similar to what they had before the weather change.

I appreciate the debate, but a hurricane is a fairly focused phenomenon in time & space. If your entire region dries up over a period of many years/decades/centuries, that is a much broader threat to survival. Some "protomen" undoubtedly moved with the receding jungle & survived relatively unchanged (for a while), while other bands changed radically.
