[QUOTE="MAKAVELI, post: 3300471, member: 43825"] The National Geographic article said the DNA may have been from a tribe that no longer exists. It's a specific trait that only passes from mother to child and has only been found in 4 Iclelandic family lineages.

For starters, no living Native American group carries the exact genetic variation found in the Icelandic families. But of the many known scattered versions that are related to the Icelandic variant, 95 percent are found in Native Americans.
