Carl Zimmer's excellent blog The Loom has a report about Spencer Wells' project to map historical human migrations using genetic sampling. (It also has a link to this interactive map of our species' history.) Zimmer says, "You can buy a DNA kit, and hen you send it back to the Genographic Project, you'll get a report on 'your genetic journey' and the information will get added to Wells's database." Gotta love that---"you can buy a DNA kit" has apparently moved from being science fiction to being as unremarkable as picking up a liter of milk. Wonder what would happen if we organized students at the University of Toronto to take part?
