This is kind of amazing news, since it’s supposed to eliminate the missing link theory from our evolution into modern humans. This means that the common ancestry between humans and apes is even further back, between 6 and 9 million years ago. Ardi walked upright, but used all four limbs when in trees.

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.

“This find is far more important than Lucy,” said Alan Walker, a paleontologist from Pennsylvania State University who was not part of the research. “It shows that the last common ancestor with chimps didn’t look like a chimp, or a human, or some funny thing in between.”
