Don’t look now but Putin has just claimed it for Russia.

Why would anyone park on cold freezing islands for 5,000 years when warm beautiful Hawaii was just sitting there??
Doesn`t make any sense.

The researchers found that mutations in the DNA indicated a group of their direct ancestors from Siberia was likely isolated for at least several thousand years in the region of the Bering Land Bridge, the now-submerged plain that lies between northeast Asia and Alaska once exposed by a significantly lower sea level.

This is statistical nonsense. Data could show that a group was genetically isolated in a small region for 5,000 years, but data cannot distinguish between genetic isolation on a land bridge, genetic isolation in some Asian terrain (whether due to ice, mountains, or culture), or genetic isolation in a North American outpost before spreading out throughout North America. The fact of extended genetic isolation is interesting, but the inference goes too far.

DNA shows that the American Indians came through Siberia from Germany. The American Indians were selfish Europeans trying to keep other Europeans from enjoying the bounty of The Americas.

I understand that many archaeologists still resist that enterprising humans came to the American continent before 13-15,000 years in the past by means other than trudging over that land bridge in their moccasins, in spite of the mounting evidence that is making them look silly-but isn’t it insulting their intelligence to say they hung out on the frozen edge of an ice sheet, housekeeping and hunting, burning sticks and bones for fuel for a couple thousand years? Especially when there was better land with more vegetation, animals and less ice a few weeks’ walk further, when they’d already walked so far...
