Thanks Renfield, SES1066, and GeronL. The evidence for continual colonization is found nearly everywhere in the Americas; there has been little genetic evidence because the number of precolumbian remains is very small, and studies of current DNA samples show what exists today, and little else.

Based on the homogeneity of the language groups, the colonization of northernmost North America from Siberia, and vice versa, apparently took place a very short time ago, or just wasn't of much interest to anyone. The 'Red Paint' culture appears to have been distributed all around the Arctic Ocean shoreline, but is believed to antedate the current "indigenous" peoples by thousands of years. They vanished, or vacated to warmer areas.

Seems like a good weekly digest topic ping, btw.

Interesting this one came up again.

Right now is the annual PaleoAmerican Conf.[I wish I was there]

The Tweets coming out right now.

So, you think they came from both directions?

There is quite strong evidence that the peculiar, almost elemental, copper deposits of the Michigan Upper Peninsula were the primary source of copper for Bronze during the Bronze Age. Sunken boats have been found in the Mediterranean with these peculiar metals. Indians have stories of tall, light-skinned explorers/extractors who managed mining and distribution of this copper.

Of course, the time of the Bronze Age (3600-1200 BC) does not represent the earlier epoch which this article refers to. However, it is strong evidence of longstanding voyages between Europe and the New World.
