(From news.nationalgeographic.com)- The Bolivian river dolphin is a separate species from the Amazon river dolphin, scientists announced recently.Thousands of years ago a powerful drought dried up Brazil”s Madeira River, causing a “radical separation” as dolphin populations were caught on different sides of the newly created rapids, said researcher Manuel Ruiz-Garcia. “Thus isolated, the Bolivian river dolphin, Inia boliviensis, eventually developed,” he said. The announcement was made at a recent conservation workshop in Santa Cruz de la Sierra in Bolivia.
