Oct.1,2009. National Geographic says, "Scientists today announced the discovery of the oldest fossil skeleton of a human ancestor. The find reveals that our forebears underwent a previously unknown stage of evolution more than a million years before Lucy, the iconic early human ancestor specimen that walked the Earth 3.2 million years ago."
The debate over why this amazingly ancient ancestor decided to go biped is an interesting one. And its mainly about sex, money and drugs!!( well not drugs, or money really...) Its the oldest profession in prehistoric times.
