<I>Homo naledi</I> Skeleton (IMAGE) University of Wisconsin-Madison Caption Skeletal fossils of Homo naledi are pictured in the Wits bone vault at the Evolutionary Studies Institute at the University of the Witwatersrand, Johannesburg, South Africa, on Sept. 13, 2014. The fossils are among nearly 1,700 bones and teeth retrieved from a nearly inaccessible cave near Johannesburg. The fossil trove was created, scientists believe, by Homo naledi repeatedly secreting the bodies of their dead companions in the cave. Analysis of the fossils -- part of a project known as the Rising Star Expedition -- was led in part by paleoanthropologist John Hawks, professor of anthropology at the University of Wisconsin-Madison.
