Shoulder bones fuel debate

By Stephen Ornes / November 16, 2012

This shoulder blade is from a 3-year-old humanlike female who lived more than 3 million years ago. Scientists are studying the fossil to learn whether the creature climbed trees. Credit: Courtesy of Zeresenay Alemseged/Dikika Research Project

Fossil shoulder blades suggest an ancient humanlike species may have been at home in the trees as well as on the ground
