WASHINGTON : A sample of Sitting Bull's hair has helped scientists confirm that a South Dakota man is the famed 19th century Native American leader's great-grandson using a new method to analyze family lineages with DNA fragments from long-dead people.
The study represented the first time that DNA from a long-dead person was used to demonstrate a familial relationship between a living individual and a historical figure - and offers the potential for doing so with others whose DNA can be extracted from remains such as hair, teeth or bones. Willerslev said he read in a magazine about the Smithsonian turning over the lock of hair from Sitting Bull's scalp and reached out to LaPointe.
"There existed methods, but they demanded for substantial amounts of DNA or did only allow to go to the level of grandchildren," Willerslev said. "With our new method, it is possible to establish deeper-time family relationships using tiny amounts of DNA."
