NYU researchers at the Tandon School of Engineering and the Grossman School of Medicine are trying to understand an age-old question that bedeviled most of us at some point: Why do all the other animals have tails, but not me? The loss of the tail is one of the main anatomical evolutionary changes to have occurred along the lineage leading to humans and to the “anthropomorphous apes.” The loss of tails has long been thought to have played a key role in bipedalism in humans.
