Before 'Lucy,' There Was 'Ardi:' First Major Analysis of One of Earliest Known Hominids (3 of 5)

Caption

Dentitions from human (left), Ar. ramidus (middle), and chimpanzee (right), all males. Below are corresponding samples of the maxillary first molar in each. Red, thicker enamel (~2 mm); blue, thinner enamel (~0.5 mm). Contour lines map the topography of the crown and chewing surfaces. This image relates to an article in the Oct. 2, 2009, issue of Science. It comes from a one-page summary by Dr. Gen Suwa of the University of Tokyo and colleagues, about their paper "Paleobiological Implications of the Ardipithecus ramidus Dentition."
