The Smithsonian's National Museum of Natural History in Washington, D.C., recently unveiled the David H. Koch Hall of Human Origins, the museum's new permanent exhibition on human evolution. There visitors can trace some six million years of human prehistory, from apelike creatures such as Sahelanthropus to anatomically modern Homo sapiens, from the first tool makers to the first artists. Paintings, sculptures, fossil replicas and even a few original fossils—including a Neandertal skeleton from Iraq—combine with interactive displays to bring humanity's extraordinary odyssey into full view.
