A decade ago, anthropologist Donald Johanson gave us From Lucy to Language, the story of the human family tree as told by fossil remains. The most famous of these remains may be Johanson's own discovery, the Lucy skeleton. Now Lucy has a relative — the recently discovered Dikika baby — and scientists are closing in on the complete gene sequence of the Neanderthal.
