I have written a book on this intriguing subject which has just been published.
In this blog I will post excerpts and other interesting texts on this fascinating subject.

Could Denisovans have reached America 130,000 years ago?

The currently accepted dates for the peopling of America are linked to the end of the Last Ice Age. And there are several reasons for this:

1. Accessibility. Humans coming from Asia (and originating in Africa) had to be able to cross the sea in what is now Bering Strait (the area is called "Beringia"), to do so, the sea level had to be lower than it is now, to allow these people to cross a dry stretch of land into America.

This could only happen during a glacial period, when the vast masses of ice that covered both northern and southern continental areas, accumulated an enormous amount of water and therefore lowered sea levels.

2. Opportunity. But this glacial period had to take place after our Homo sapiens ancestors left Africa, and this is believed to have taken place some 100,000 years ago. So these guys had to trek across Asia to reach America and this would take time... after all, no human remains have been found in eastern Siberia earlier than 50,000 years ago (at Tuyana in the Tunka Rift Valley, Siberia).th

So this means they had to reach Bering Strait area sometime after 50 Kya and cross into America before the glaciers melted (some 15,000 years ago).

This means humans crossed Siberia during the cold ice age period, reached Beringia (which was high and dry), and then entered America before the glaciers melted, engulfing the dry plains of Beringia (now under the cold sea of the North Pacific, Bering Strait and south Artic Sea).

However their entry into America required that the gigantic masses of ice that covered Alaska, Canada and the Rocky mountains, to melt to let them into the southern areas of the North American continent (what is now the US).

This took place some 14,000 years ago. Before then they were stuck in Beringia, which was beginning to flood. Of course they could have also boated down the Pacific coast of Alaska and Canada into the US, or even walked along areas now submerged by the sea, which at that time were dry land.

These are the reasons that scientists adopt the last Ice Age as the date for the earliest peopling of America.

However a similar situation took place at the end of the previous Ice Age, a period known as the Eemian (or Sangamonian Stage), which corresponds to Marine Isotope Stage 5e. It also has other names: last interglacial, Valdivia, Riss-Würm,Kaydaky, Milulin, and Kaydaky periods.

The Eemian began as the Penultimate Glacial Period ended 130,000 years ago. It was followed by a warm spell, which would have let any "humans" into America as the melting ice flooded Beringia. It was followed some 115,000 years ago by the next and final Ice Age.

Humans would have had to be present in Siberia and Beringia 130,000 years ago, but according to current orthodoxy, they were still in Africa at that time.

See the map below: in red is the land that is now submerged below the sea, which was dry during the last ice age. In pale blue, lakes that were formed by glacial dams. A similar geography existed 130,000 years ago.

Could Denisovans or even Neanderthals have crossed into America along the dry Beringian plains?

Or, Homo erectus do the same, during any of the previous glacial periods...

  1. i knew youd touch on this! been looking into the same thing recently...giant skeletons in america, while a dubious topic, i think point to densiovans. note the size of known denisovan molars. they would be big guys.
