Scientists say they’ve found a new species of human ancestor
Mental Floss: Yohannes Haile-Selassie, adjunct professor of anthropology and fellow of the Institute for the Science of Origins, and his team of researchers found teeth and jawbones from between 3.3 and 3.5 million years ago at a site 20 miles from where Lucy, who was the oldest and most complete human ancestor for decades, was found in Ethiopia. The bones suggest that there may be a new species of human ancestor.
