Anthropologist Yohannes Haile-Selassie from the Cleveland Museum of Natural History worked on the new analyses of the bones. His studies explore the earliest human ancestors that walked upright. He told Science News that the newly discovered ancient species could climb trees and walk on two legs — although upright travel would have been difficult for this animal.
