A project spanning five continents is aiming to map the history of human migration via DNA.
The Genographic Project - a partnership between National Geographic and IBM - will collect DNA samples from over 100,000 people worldwide.
Computer and lab analysis of samples - gathered from indigenous groups and the public - will help piece together a picture of how the Earth was colonised.
Team leader Dr Spencer Wells calls the plan "the Moon shot of anthropology".
The $40m, five-year project has brought on board some of the world's top population geneticists as well as leading experts in the fields of ancient DNA, linguistics and archaeology.
