Scientists Fight University of California to Study Rare Ancient Skeletons

SAN DIEGO — Two ancient skeletons uncovered in 1976 on a bluff overlooking the Pacific Ocean, during construction at the home of a University of California chancellor, may be among the most valuable for genetic analysis in the continental United States. Dated between 9,000 and 9,600 years old, the exceptionally preserved bones could potentially produce the oldest complete human genome from the continent.

But only if scientists aren’t barred from studying them.

Attempts to unlock the skeletons’ genetic secrets are stalled in a dispute pitting UC scientists against their own administration. Five of the scientists wrote with alarm in a letter published May 20 in the journal Science that UC administrators aren’t allowing studies on the skeletons, which were discovered on property owned by UC San Diegoin La Jolla, California.

Before samples can be extracted for genetic analysis, the scientists fear administrators will give the bones to politically powerful local Native Americans who could permanently block study.

“To give them away without study, would be like throwing the genetic crown jewels of the peopling of the Americas in the ocean,” said Eske Willerslev of the University of Copenhagen in Denmark, who is among about a half dozen researchers who have unsuccessfully sought in recent months to sample or study the bones. “It would be a major loss for all, including Native Americans.”

A few studies were done years ago on the skeletons before UC withdrew access to them, but recent technological advances would allow scientists to do much more, including a digital skull calibration and possibly a full genome sequence.

“The potential loss of the La Jolla skeletons would have a profoundly negative impact on our knowledge of the peopling of the Americas,” wrote the authors of the letter, led by Margaret Schoeninger, an anthropologist at UCSD.

Science letter co-author Tim White, a prominent paleoanthropologist at UC Berkeley, told Wired.com, “Administrators are doing everything they can to ignore the scientific value of the specimens. They are trying to illegally repatriate them to a lobbyist for a dozen San Diego County tribes.”

UC officials are seeking to provide the skeletons to the Kumeyaay Nation east of San Diego under a complex process guided by the federal Native American Graves Protection and Repatriation Act (NAGPRA). But critical scientists say NAGPRA requirements aren’t being followed properly, setting the stage for a potential legal battle over the bones.

“This is Kennewick Man II,” White said, referring to the long federal court battle in 2004 when scientists won the right to study bones found in Washington.

In a May 11 letter, Mark Yudof, president of the 10-campus UC system, authorized UCSD chancellor Marye Anne Fox to dispose of the bones — after clarifications are made to a report done under NAGPRA requirements, and other tribes that may be interested in the bones are consulted.

Steve Benegas, the repatriation spokesman for the Kumeyaay nation’s 12 tribes, said they are entitled to the bones and to decide about future analysis. Some Native Americans believe scientific research amounts to desecration of remains, and Benegas said he personally is against studies.

“The university has handled this poorly over the years,” he said. “We have no trust in them. They have treated the remains of our ancestors without respect.”

One of the previous analyses done years ago showed the bones have connective tissue and amino acids that are used in cell function. This means it is very likely ancient DNA can be extracted. And two skeletons buried together offers a rare opportunity to compare their genomes to see if they were related.
