Carl Zimmer in his blog, The Loom:
This morning the New York Times reported that the National Geographic Society has launched the Genographic Project, which will collect DNA in order to reconstruct the past 100,000 years of human history.
I proceeded to shoot a good hour nosing around the site. The single best thing about it is an interactive map that allows you to trace the spread of humans across the world, based on studies on genetic markers.
More here. Do check out the interactive map (and the rest of the post).
