Relethford co-authors journal article

John Relethford, Anthropology, is a co-author of the paper “Bone functional adaptation does not erase neutral evolutionary information” in the American Journal of Physical Anthropology (Early view online). The other authors are Gina Agostini (senior author, Arizona State University) and  Brigitte Holt (University of Massachusetts). This study examines measurements of long bones taken by the senior author in samples from Europe and South Africa to examine the extent to which variation among samples reflects population history (judged using cranial measures) versus adaptive plasticity due to changes in the bones over a lifetime. The results indicate that adaptive plasticity does not erase population history.
