Lucy, the famous 3.2-million-year-old hominid skeleton, had strong upper arms to help her climb trees according to researchers. John Kappelman, a paleoanthropologist at the University of Texas at Austin, said Lucy “combined walking on two legs with a significant amount of tree climbing.” The debate about whether Lucy’s species spent most of their time walking on land or in the trees has continued since her discovery in 1974. However, since further measurements and x-ray CT scans of her upper arms, scientists have somewhat confirmed Lucy’s arm’s to be more similar to those of primates.
