If the story of human evolution is a puzzle, scientists recently found another piece. Last month, a team of researchers announced the bones of a new human ancestor were recovered from a narrow cave in South Africa. Now, the work is underway to find out as much as possible about Homo naledi. Since the hands of the species can reveal a lot about how it spent it's days -- scientists started there. Caley Orr is assistant professor of Cell and Developmental biology at CU Anschutz, and helped examine the hand of this new species. Orr spoke to Nathan Heffel.
