Washington Scientists hoping to study the ancient skeleton known as Kennewick Man are protesting efforts that they say could block them from examining one of the oldest and most complete set of bones ever found in North America.
For the third time in four years, the scientists oppose a Senate bill that would allow federally recognized tribes to claim ancient remains even if they can't prove a link to a current tribe.
They also are contesting draft regulations issued by the Bush administration on disposal of culturally unaffiliated remains.
Both measures could end up with the same result, scientists say: preventing an improved understanding of North American history and the role of the continent's first inhabitants.
If adopted, the proposed changes could "result in a world heritage disaster of unprecedented proportions" and "rob our descendants of the unique insights concerning the shared heritage of all people that physical anthropological studies of culturally unidentifiable human remains can provide," the American Association of Physical Anthropologists said in a statement.
Supporters call such concerns overblown. They say the changes are intended to clarify the Native American Graves Protection and Repatriation Act, also known as NAGPRA, to ensure that federally recognized tribes can safeguard the graves of their ancestors.
Neither the Senate bill nor the draft regulations would affect the 9,300-year-old bones known as Kennewick Man, they said. The skeleton was discovered in 1996 along the Columbia River near Kennewick, Wash., and has been the focus of a bitter fight ever since.
A federal appeals court ruled in 2004 that scientists can study the ancient bones, and teams of anthropologists and other analysts have begun poring over more than 300 bones and bone fragments at the Burke Museum of Natural History and Culture in Seattle, where the remains are housed.
A spokesman for Sen. Byron Dorgan, D-N.D., chairman of the Senate Indian Affairs Committee, said the Senate bill would clarify what process should be followed for future discoveries of ancient remains.
"The court ruling said it's not clear" what should happen, "so Congress wants to clarify what its intent was - and its intent is that tribes that believe they have a connection (to ancient remains), either through descent or cultural affiliation, have an opportunity to make that case," said Barry Piatt, a Dorgan spokesman.
The Bush administration opposes the Senate bill, which mirrors legislation proposed in 2004 and 2005. In testimony before the Indian Affairs Committee in 2005, Paul Hoffman, a deputy assistant Interior secretary, called the proposed change too broad and said it would loosen the Indian graves law to include remains that might not be connected to a tribe.
Hoffman said the grave protection act "should protect the sensibilities of currently existing tribes, cultures and people while balancing the need to learn about past cultures and customs." In cases where remains are not significantly related to any existing tribe, people or culture, they should be available for appropriate scientific analysis, he said.
