wow I bet after this came out the ‘feces hit the fan’ with the European-clovis theorists.
of course this proves that Asian made it to the Americas. it doesn’t and can’t deny the European, westward, follow the ice sheets, theory.
During the period of my life when I was learning a lot more than I was forgetting, Clovis was the marker for the earliest human presence in the Western Hemisphere and it coincided with the presence of an ice free corridor across the Bering Strait and down through Alaska to the edge of the Continental Ice Sheet. This became the anchor for a simplistic theory that there was a single wave of migration, by land, from Siberia.
That theory has endured assault after assault in the years since, with a building body of evidence that like many other parts of the world, the Americas probably experienced waves of migration by various means over a long period of time and likely not just limited to movements from Asia. DNA has helped because we have good data to show halogroup distribution from both present and ancient populations. When I was a pup, science had just discovered DNA and had no idea what information was within those double helixes.
Our knowledge has expanded exponentially within my lifetime and will likely do so again in my children and grandchildren’s lifetimes. Check back again in 50-75 years and you will find that we have a much richer story and we will have discovered that some things that we thought was true today, wasn’t. People never needed the internet and frequent flyer miles to get around when they wanted to.
