The 81st Annual Meeting of the American Association of Physical Anthropologists (2012)

Session 25. Early Man in South America: New paradigms in Late Pleistocene / Early Holocene biological anthropology. Invited Podium Symposium. Chair: Mark Hubbe and Andre Strauss

Friday Afternoon, Grand Ballroom II Add to calendar

In 1912, Aleš Hrdlicka published his critical review of the existence of early man in South America based on his own expedition to Argentina. His main concern was an evaluation of the available evidence for an early human presence in the continent so that he could attempt to understand its implications for the general framework of human evolution that was under discussion at the time. Hrdlicka considered each aspect of the broader archaeological context including chronology, taphonomy, and geoarchaeology. On the centennial of this seminal work, this two-part symposium, presented at the SAA and AAPA, is intended as an homage that critically reviews the processes of modern human dispersion into South America and their relevance for the understanding of modern human history. The first part, presented here, focuses on the bioanthropological aspects of these topics. The partner to this session will be presented at the 77th SAA meeting, focusing on the archaeological perspective of human dispersion into the continent. In this session, we aim to discuss: 1) the biological origins of early South Americans from the perspective of South and North American anthropologists/geneticists; 2) intra-continental biological diversity and dispersion routes; 3) micro-evolution of humanity in South America since its initial settlement emphasizing biological adaptation and diversification; and 4)dispersion scenarios for human groups within the continent.
