Zeray called the baby Selam, the Ethiopian word for peace.
Then he set off on a quest to unravel her many mysteries. Imagine the entire span of recorded human history, taking us back to the Egyptian pyramids, about 5,000 years.
And keep doubling, six more times, taking us back 1.3 million years, when the first creature who really looked like us hunted on the plains of Africa. His challenge is to release her from the tomb of sandstone in which her bones are encased. She's from a species considered by most scientists to be an ancient ancestor, Australopithecus afarensis: a small, chimp-like creature who walked on two legs.
And then keep traveling back another two million years, and only then do we arrive in the time when Selam lived in Ethiopia nearly three and a half million years ago. This is the same species as the famous Lucy, discovered in the 1970s by Don Johanson.
