The author of this article seems to make stuff up. So here are some bullet points for standard American archaeology.
- Clovis first had been questioned for quite some time. It had in it’s favor no hard evidence for any other hypothesis until Meadowcroft was excavated. That was in the 1970’s. The Brits seem to have just gotten the news.
- Native Americans had been in the New World a long time before Clovis which is what the Paisley Caves (DNA) and Meadowcroft (artifacts) finds are about. They are different cultures produced by related people (this idea confuses the author).
In summary, Clovis Native Americans aren’t the first Americans only because their ancestors got here before them. To add to our knowledge, we now know they ate flying elephants.
Don’t forget Topper in South Carolina and Cactus Hill in Virginia. It was Professor Goodyear at Topper who had the unorthodox idea to keep digging below the Clovis layers. Here he found many non-Clovis points that preceded Clovis by another several thousand years! They then dug at the other sites including Meadowcroft and found lots of evidence below. I think they went down 11.5 feet at Meadowcroft finding human tool remains.
I still like the trans-Atlantic seal hunter theory. Note that all of the EARLIEST sites (that is, pre-Clovis) were on the EAST coast.
