20,000 years ago plus

5 Jan 2018

At https://phys.org/print434179901.html ... excavations at a site in Alaska have found genetic lines of early Native Americans that may have entered N America more than 20,000 years ago. The findings are published in the journal Nature (January 2018). It is though they arrived from Siberia and continued to have contacts with Siberia for a considerable period of time - finally losing that contact at the end of the Ice Age. The Bering Land Bridge is touted as their route of entry - but equally they could have arrived by boat. They are also being touted as the ancestral population - mainly  because they have more ancient features than other Native Americans (who are assumed to have broken away from them). Lots of question that the full article would perhaps explain but the geneticists are saying this group emerged around 36,000 years ago. This is a very significant date as it was around this time that Neanderthals in Europe and western Asia were replaced by modern humans. Was something similar going on in eastern Asia?

The same story is at https://anthropology.net/2018/01/04/ancient-dna-reveal-the-foundation-ev... ... where we learn the site is in the Tanana River Valley in central Alaska. This was made famous by the 19th century gold rush - and is home to the muck deposits featured in Velikovsky's 'Earth in Upheaval'. He was perhaps not far wrong when he claimed human worked stone tools had been found in the frozen muck. He was mocked at the time because Clovis First dominated N American archaeology - even though they were not prepared to look at the field evidence first hand. Seems like the reports he used were right after all. Humans were in Alaska during the Late Pleistocene.
