image: In modern human and Neanderthal hands, the wrist bones are shaped such that forces are better distributed across the front of the wrist from the base of the thumb toward the pinkie finger. In great apes and older hominins (e.g. "Lucy"), the wrist bones are not shaped like this. This image relates to an article that appeared in the Sept. 21, 2007, issue of the journal Science, published by AAAS. The study, by Dr. Matthew W. Tocheri and colleagues at Smithsonian Institution in Washington, D.C., was titled "The Primitive Wrist of Homo floresiensis and Its Implications for Hominin Evolution." view more
