The title of this article is "Civilizations Lost and Found: Fabricating History. Part Three: Real Messages in DNA" and it addresses the claim made in the documentary that the presence of the mitochondrial DNA haplogroup "X" in American Indian populations provides evidence for a pre-Columbian migration of Israelites to the Americas.
