I believe the big debate is now on how they moved through North and South America. The older view had them using the Bering Land Bridge and basically walking all the way to Tierra del Fuego.

A newer idea is that they did a lot of moving by boat. Some very old sites exist in Chile, which should be one of the last places to be settled if they walked. Also interesting is the fact that even today, it is virtually impossible to walk to South America from North America.

It is not very difficult to hike the Darien Gap. It can be done in a few days.

The difficulty is in not having fun confrontations with guerillas and drug runners.

30,000 years ago the sea level was about 400 feet lower because much of the water was tied up then Ice Age glaciers.

Hmmmm.... my family helped build the Panama Canal and it was never a bother to cross the isthmus of panama between north and south America.

So wth are you talking about?
