From Austin to Ushuaia

An article in the New York Time, Arrowheads Found in Texas Dial Back Arrival of Humans in America by John Noble Wilford today, finally provides a possible explanation to a puzzle. I was very surprised, going to Ushuaia, to see how close the indigenous culture (that died as recently as the 20th century) was to that of North America, although the distance is enormous. Coastal migrations discussed in the article to explain the presence of pre-Clovis artifacts in the hills of Austin (the migrations had to be coastal because of the ice barriers 15,000 years ago) can also explain, as the article mentions, the speedy population of Peru and Chile. While Argentina is on the other side, it's not that far away in the south and waterways are aplenty.
