    Department of Anthropology, Washington University, St Louis, Missouri, United States of America
    PLoS ONE 4:e7783. 2009

    J Exp Biol 210:484-94. 2007

    J Hum Evol 54:112-7. 2008

    Department of Anthropology, University of Arizona, Tucson, AZ 85721, USA
    Am J Phys Anthropol 138:395-402. 2009
