I actually watched a vid a few years back, narrating the discovery of 55,000(!!) year old human remains in Brazil, along with Aboriginal Australian genetic markers, found in an isolated Native American people in Tierra del Fuego, at the southernmost tip of Chile, and the explanation was that, quite possibly, pretty soon after reaching Australia, ancient humans went sailing further and further on, just like the much later Polynesians did - and, unlike them, they had even reach South America.

Could they have also later came from there to North America, and those are them, then?
