SUMMARY

The discussion centers on new evidence challenging the Clovis-first model of human migration into America, specifically a projectile point made from mastodon bone found embedded in a rib at the Manis site in Washington. Radiocarbon dating indicates the rib dates back to approximately 13,800 years ago, based on an average of four carbon dates of 11,960 +/- 17 years 14C B.P., which translates to 13,860 - 13,763 calendar years B.P. This evidence suggests a need for a paradigm shift in archaeological thinking, as the Clovis-first model has been increasingly questioned by the scientific community.

PREREQUISITES
  • Understanding of radiocarbon dating techniques
  • Familiarity with the Clovis-first hypothesis in archaeology
  • Basic knowledge of archaeological methods and evidence interpretation
  • Awareness of the significance of the Manis site in Washington
NEXT STEPS
  • Research the implications of the Clovis-first model on North American archaeology
  • Study the methods and accuracy of radiocarbon dating
  • Explore other archaeological sites that provide evidence of pre-Clovis human presence
  • Investigate the impact of DNA analysis on understanding ancient human migration
USEFUL FOR

Archaeologists, anthropologists, historians, and anyone interested in the early peopling of the Americas and the evolution of archaeological theories.

For some reason, incomprehensable to me, archeologists and antropologists have fought flaming wars about the peopling of America. Maybe that has to do with my new signature.

Anyway, the clovis first protagonists may have some work to do after http://www.sciencemag.org/content/334/6054/351.abstract:

The tip of a projectile point made of mastodon bone is embedded in a rib of a single disarticulated mastodon at the Manis site in the state of Washington. Radiocarbon dating and DNA analysis show that the rib is associated with the other remains and dates to 13,800 years ago...

I wish to know if that date 13.8 Ky is 14C years or calendar years. But I guess I'll find out soon.

Thoughts?

Update, yes, After getting the article, the date is based on an average of 4 carbon dates of 11,960 +/- 17 years 14C B.P. which is converted to 13,860 - 13,763 calendar yr B.P.
 
here is a "biased" subjective coverage of the article.

How about this conclusion and my new signature:

"You know, the Clovis-first model has been dying for some time," he finished. "But there's nothing harder to change than a paradigm, than long-standing thinking. When Clovis-First was first proposed, it was a very elegant model but it's time to move on, and most of the archaeological community is doing just that."
