Wow...I never saw this. Have they ever done DNA tests on the Tierra del Fuegans to see if they are indeed related to Aussie aborigines?
I don't know.
When Alexander von Humboldt was in the area around 1800, he said he encountered two different people. One was short and stocky and made their living from the sea and wore few clothes.(I was reminded of Eskimos)
The other was tall, lanky and made their living on the land and wore animal skin clothes.
