Glass shard (IMAGE)
Caption
A tiny glass shard less than the diameter of human hair was recovered from a Middle Stone Age site in northwest Ethiopia. Its chemistry matches that of the Toba supervolcano located on the other side of the world in Indonesia. The people who lived at this archaeological site survived the supereruption because of their behavioral flexibility.
