Areas of Expertise

primate functional morphology, postcrania, paleoanthropology, locomotion, cartilage and joint function

Dr. Ashley Hammond is a functional morphologist interested in the evolution of locomotor behaviors in great apes and hominins.  Most of her work focuses on the functional anatomy of the primate pelvis and femur, two anatomical regions that are extremely different between apes and hominins and reflect different locomotor specializations.  She is currently leading (with Sergio Almécija and Jeroen Smaers) an externally-funded project that aims to reconstruct the expected morphology of the chimpanzee-hominin last common ancestor (LCA) under different evolutionary scenarios.  This study will allow researchers to evaluate claims of how closely the morphology of early fossil hominins, such as Ardipithecus, match the expected LCA morphology under different evolutionary scenarios.  Dr. Hammond is also currently describing and analyzing new fossil material from Kenya, Ethiopia, Egypt, Spain, and Italy.

Prior to coming to GW, Ashley Hammond completed her dissertation at the University of Missouri, supervised by Carol Ward.  Her dissertation research developed a 3D model of hip joint mobility in anthropoids, which was validated against live animal measurements of hip joint mobility.  This modeling approach tested for differences in range of hip mobility in extant species associated with different locomotor adaptations, and allowed Ashley to then test locomotor reconstructions in key fossil ape taxa.  Immediately after the completion of her PhD, Dr. Hammond was an instructor at Stony Brook University, where she taught human gross anatomy to health professions students.
