Lucy, the famed fossilized skeleton of one of the oldest human ancestors, is coming to visit the US from Ethiopia where Donald Johansen and his colleagues discovered her in 1974. Surprisingly, Lucy won't be on display at two of the premier natural history museums in the country, the Smithsonian's National Museum of Natural History and the American Museum of Natural History in New York City. Why? Those are just two of the museums who refused the exhibition, arguing that the fragile bones should remain in Ethiopia and not subjected to six years of touring and public display. The exhibit, titled The Hidden Treasures of Ethiopia, is hosted and sponsored by the Houston Museum of Natural Science.
