A collaborative research project involving NYU Anthropology undergraduate students, graduate students, alumni and faculty has just been published in PLoS ONE. The study, led by doctoral student Alejandra Ortiz, used 3D geometric morphometrics to re-examine Bunopithecus sericus, a fossil gibbon from the Pleistocene of China. The paper concludes that Bunopithecus should be recognized as a distinct genus and that it is most closely related to the living hoolock gibbons.
