Relatively new information has shown there were likely people in North America before the so-called Clovis occupants around 13,000 years ago.

Previous genomic studies have suggested the first American populations diverged from their Siberian and East Asian ancestors nearly 25,000 years ago and then split into distinct North and South American populations about 10,000 years later.

And this:

The researchers also discovered a population about 11,700 years ago that had Australasian ancestry evident only in South America (it hasn't been found in North America yet).
