Some of you may have already met Lucy of Hadar over in Twitterland. She has taken over the Twitter feed that I formerly wrote and having a great time with it.
Lucy lived 3.2 million years ago. We know that because scientists used several highly sophisticated methods to date the ash in which an archeology team found her bones in the Hadar region of Ethiopia in 1974.
The archeologists were excited because they had found nearly 40 percent of Lucy’s skeleton and could tell from her knee bone that she walked upright. At the time, that made her our oldest human ancestor. The bone fragments were scattered and it took a few weeks to determine that they all belonged to one person.
“Lucy brought with her an image of our human ancestors you don’t get when you find a jaw or an arm bone or a leg bone.”
