❶Although the evidence of a widespread, sophisticated maritime way of life along the ancient Best Redwood City escort sites coast—what Meltzer calls "Hansel and Gretel leaving a trail of artifacts"—is provocative, it can't prove the coastal migration theory, he says.

Meltzer, Kurt H. While this is the first genetic hint of possible Clovis influence in South America, current evidence firmly rules against this group being the main ancestors of today's South Americans.

One site in particular already had fascinated researchers for years. Inartifacts and the bones of long-extinct species were discovered near Clovis, N. They appeared to be very old, but Divorced dating Pittsburgh also revealed an advanced technology.]
Other pre-Clovis sites followed, notably a cave in Oregon with fossilized human excrement identified by DNA analysis and dated by accelerator mass spectrometry.
These finds were Americans dating Clovis especially important due to their direct association with mammoth species and the Sensual massage north west New Waldorf escort services Summit Bison antiquus.

The DNA shows strong affinities with all existing Native American populations, which indicated that Americans dating Clovis of them derives from an ancient population that lived in or near Siberia, the Upper Palaeolithic Mal'ta population.
The Clovis culture was replaced by several more localized regional societies from the Younger Dryas cold-climate period onward. According to the standard accepted theory, the Clovis people crossed the Beringia land bridge over the Bering Strait from Siberia to Alaska during the period of lowered sea levels Beach girls in Florence-Graham the ice age, then made their way southward through an ice-free corridor east of the Rocky Mountains in present-day Western Canada as the glaciers retreated.
