The 89th Annual Meeting of the American Association of Physical Anthropologists (2020)

Session 38. The Extended Evolutionary Synthesis and Human Origins: Paleoanthropological Perspectives. Invited Podium Symposium. Chair: Robert A. Benitez Co-organizers: Robert Acio Benitez (School of Anthropology, University of Arizona); John K. Murray (School of Human Evolution and Social Change, Institute of Human Origins, Arizona State University)

April 17, 2020 2 p.m. - 5 p.m., Diamond 4 Add to calendar

The theoretical framework in which researchers examine and interpret data influences the primacy of questions posed, hypotheses tested, and, ultimately, knowledge produced. For paleoanthropologists, the Modern Synthesis (MS) has historically guided inquiry and interpretation of the hominin fossil record. Recently, scholars in several disciplines have found MS to be lacking in its explanatory power, particularly with relevance to the emergence and evolution of the human lineage. Proponents of a theoretical revision, coined the extended evolutionary synthesis (EES), argue for a broader framework of contemporary theory that places emphasis on the role of diverse and reciprocally interacting evolutionary forces (e.g., developmental plasticity, niche construction) and inheritance systems (e.g., genetic, ecological, cultural). This symposium will address what an alternative perspective means for framing paleoanthropological inquiry. In particular, we aim to discuss the possibilities and limitations of exploring human origins under a larger suite of theories encapsulated within EES.
