Native American Darrell Crawford's DNA goes back to 55 generations, the oldest DNA ever discovered on the American continent.
The genetic research company CRI Genetics has discovered the oldest DNA of an American. The results are 99 percent accurate and indicate that the Crawford lineage has been going back for 55 generations or 17,000 years.
So long dating of the lineage through DNA analysis has never been so successful, so this reconnaissance is very important in the field of biogeography.
Crawford is a member of the Blackfoot Indian Reserve in Montana. He and his community believe their ancestors settled on the American continent during the Ice Age when they came from Asia via the Bering Land Bridge.
However, DNA results say his ancestors first lived in South America where they came from the Pacific islands.
