For many years the consensus among archeologists was that humans began settling in North America around 13,000 years ago. Deze tijdlijn was gebaseerd op artifacten gevonden die dateren terug tussen 12.700 en 13.000 jaar, inclusief wapens. Now, a new discovery in Texas could throw that theory right out the door.
Researchers from Texas A & M, Baylor University, and the University of Texas have uncovered what they believe to be spear points that were used by human hunters as far back as 15,500 years ago. The discovery pre-dates the accepted timeline for the settlement of North America by a significant margin, and scientists may be forced to rethink when and where the first groups of humans pushed into what is now the United States.
“There is no Michael Waters of Texas A & M, lead author of the paper published in Science Advances said in a statement. “The discovery is significant because almost all pre-Clovis sites have stone tools, but spear points have yet to be found. These points were found under a layer with Clovis and Folsom projectile points. Clovis is dated to 1
3,000 to 12,700 years ago and Folsom after that. The dream has always been to find diagnostic artifacts – such as projectile points – that can be recognized as Clovis and this is what we have at the Friedkin site. ”
It’s thought that hunting was what drove groups of ancient peoples into new areas, and at the time the spear points may have been used in hunting efforts against large game like mammoths. Men, det var ikke som om settlere eller ålder hadde kort eller en vag forståelse for hvordan den kontinent var formet.
With that in mind, it’s easy to see why determining when human settlers arrived is such a difficult box. Smaller groups may have come and gone over time, and progress would have been slow.
