The National Geographic Society's Genographic Project, a long-term anthropological study to map the world's DNA, obtains results about a person's deep ancestry dating back up to 100,000 years. The Genographic Project's results trace migratory paths of a participant's ancestors as recently as a few hundred years ago, give participants a percentage breakdown of genomic ancestry associated with specific regions, can determine how much Neanderthal or Denisovan ancestry they have and place people on a branch of the human family tree.
Participants' results are stored on the Genographic Project website where they can log on and get information on which deep ancestral branch (haplogroup) they most likely belong to.
A small sample of 326 Puerto Rican subjects supports, but does not prove, theories that Taino men were wiped out by Spaniards in the 15th century, while Taino women survived and procreated with the Spanish invaders. Sixty percent of mitochondrial DNA samples from women showed Taino ancestry, while zero percent of Y chromosome DNA samples showed Taino ancestry. Since mitochondrial DNA is only passed through maternal lines and Y chromosome DNA is only passed through paternal lines, these results support this historical theory.
The project is not a genealogical ancestry service and is not intended to determine paternity, obtain medical information or to obtain criminal information.
