To help us learn about our ancestry and how they migrated, National Geographic has created the Genographic project. The Genographic Project is a non-profit and non-medical five-year-long anthropology study, led by Spencer Wells, a National Geographic Explorer-in-Residence, and a crew of renowned international scientists and IBM researchers. The program collects and analyzes DNA samples and charts human migration routes. Collaborating with traditional and indigenous peoples around the world, its main goal is to "understand our human genetic roots."
As you may know, all of our ancestors came from Africa. About 60,000 years ago, groups of Africans left their homeland. From there, they crossed land bridges and traveled to foreign lands.
These DNA studies are derived from Charles Darwin's On Origin of the Species, explaining that all humans are traced from common ancestors. The Genographic Project is going even into more depth.
For US$100, you can find out about your own family's ancestry with a self-testing kit that includes a buccal swab and it is analyzed on an Internet database. More than 300,000 have already purchased theirs.
