The Genographic Project, run by IBM Research and National Geographic, has collected 470,000 DNA samples from the public by employing a thorough ethics policy. The research has contributed towards the genomics and computational biology areas by finding support for a migration route from Africa to South India.

This supports a southern route of migration from Africa via the Bab-el-Mandeb Strait in Arabia, before any movement heading north.
