The fact that Southeast Alaska Native elders approve of the experiment - just as they earlier endorsed requests to examine the human remains - contrasts sharply with the protests and pitched legal battles Indian leaders in Washington state waged over the fate of "Kennewick Man," the 9,000-year-old Columbia River skeleton.
Tlingit elder Rosita Worl, president of the Sealaska Heritage Institute - the Southeast Alaska Native non-profit group that's helping stage the study - partially credits the institute's Council of Traditional Scholars.

"When this 10,300-year-old person was found on Prince of Wales, the way it was interpreted was that we had one of our ancestors offering himself to give us knowledge," Worl said. "They were also saying that if our culture is going to survive and flourish, then we have to be receptive to science."

Scientists used to think migrating groups simply walked across the 1,000-mile wide Bering Land Bridge and bided their time around present-day Fairbanks - at least until about 12,000 years ago, when the glaciers that blocked the centre of the continent finally began to melt, opening an ice-free corridor south.

But that long-accepted migration theory has grown problematic of late, as scientists keep discovering evidence of earlier Americans living south of Alaska - including humans in Monte Verde, Chile, 12,500 years ago, and on an island off California 13,000 years ago, and inside a coastal Oregon cave 14,300 years ago.

They could have got there, some scientists believe, simply by paddling the coast.

"Monte Verde, Chile, 12,500 years ago"?
Afaik Monte Verde was dated at 14,400 years BP!

multiply must be totally beyond them.

Imagine the depression that the 3 miles thick ice sheet causes on Antarctica! I've seen calculated geological assessments that project that Antarctica's ground surface will rise around 1,200' – yes, that's twelve hundred feet! – should the ice pack melt away.
