Scientists at Johns Hopkins Medicine and the Philadelphia College of Osteopathic Medicine report new evidence that some 5,000 years ago, a sloth smaller than a black bear roamed the forest floor of what is now the Dominican Republic in the Caribbean Sea, living a lowland life different from its cousins on the other side of the island. The newly identified mammalian species—now extinct—was smaller and had anatomical differences in its forelimb that gave it greater range of motion, possibly to help the animal occupy more lowland areas than its tree-dwelling kin.
