Ancient footprints in New Mexico reveal new evidence of Ice Age humans that walked

3. The really old fossil humans they found in Brazil some years ago

were initially thoght to be from Africa, which would have made sense, it's not that long a voyage.

What they found was more astonishing, they were from east Africa,all right, but by way of Melanesia and Australia.

Either there were a lot more islands poking their heads up in the Pacific for island hopping or they were hunters who hunted close to Antarctica and traveled up the east coast of S. America.

While DNA tells us the largest migration was from Siberia through Beringea, it seems clear they didn't find a land mass empty of humans.

As for Neanderthals and Denisovans, they don't seem to have survived beyond the Campanian Ignimbrite Eruption, the one that spread ash from present day Naples into central Siberia and most likely ushered in centuries of intense cold.
