New evidence from oldest human settlement in the Americas

It seems they're always deciding when different populations migrated to different parts of the world, then they find evidence it was more complicated than they imagined. All part of a puzzle, that we find more pieces of all of the time.
Still, unless they can find an eye witness, imagination will always have to play a part. Our roots are much deeper than we've discovered so far.

It may be that we have knowledge of less than 1% of all the circumstances of human existence. We assume we know so much.
