Answer 3

According to research published in the current issue of Quaternary Science Reviews, the wall of ice that supposedly blocked any maritime explorers disappeared nearly 17,000 years ago, giving those immigrants an extra couple of thousand years to make it down to South America. They may have walked along the beach when they could, and built crude vessels when they could travel only by water.

And it's the only way, so far, to explain how they got to South America 14,000 years ago. The other possibility, that they somehow sailed across the Atlantic or Pacific, has not been well accepted by archaeologists.

This discovery isn't going to end the debate. But it's a critical piece of evidence that until now has been missing.
