Ancient genomics is recasting the story of the Americas’ first residents

"Scientists discerned that groups crossed the Bering land bridge from Siberia into present-day Alaska and then moved steadily south as the last Ice Age ended. Humans carrying artefacts from a culture known as Clovis, including sophisticated projectile points, began to populate the interior of North America around 13,000 years ago. For decades, researchers thought that people associated with this culture were the continents’ first inhabitants.

But the discovery of ‘pre-Clovis’ settlements — including a nearly 15,000-year-old site at the southern tip of Chile — pointed to an even earlier wave of migration to the Americas, presumably also over the Bering land bridge."

I think we should be reminded of these simple historical facts over and over. Lets not forget our history and that truly we are all ONE - Asians, Americans, Russians etc. We come from the same home and born from the same parents.

"Presumably also over the Bering land bridge" , certainly a big presumption giving that boats are a preferred means of long distance travel, but proving as such so far back must be practically impossible.
