Description
English:

Informative graph of the kernel density estimation (KDE) model results. Age of carbon-dated seeds averages between 23,000 and 21,000 years ago.

The results using the KDE model were ground breaking in challenging the widely accepted timeline of human evolution in North America. The radiocarbon dating of ancient seeds suggests that humans were present in the Southwest 23,000-21,000 years ago, before the Last Glacial Maximum (LGM).
