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


Session 44. A Two-Way Street Tale: Integrating Biocultural Data for Discussing Past Human Diversity in the Americas. Invited Poster Symposium. Chair: Lumila P. Menendez Co-organizers: Mark Hubbe, Department of Anthropology, The Ohio State University, USA.

April 17, 2020 1 p.m. - 5 p.m., Diamond 7 Add to calendar

The study of the origin and evolution of the past human biological variation in the Americas has been approached from different points of views, through the analysis of molecular (Y-chromosome, mitochondrial-DNA, autosomal markers), morphological (cranial, dental, postcranial), and cultural (linguistic, lithic technology, physical activity) data. Over the past two decades, hundreds of articles, analyzing both extant and prehistoric individuals, have been published with the goal of elucidating the complex set of processes by which Native American populations diversified and evolved across space and time. However, despite this immense scientific effort, these studies have not been able to agree on the processes that gave rise to human diversity in the continent and have supported widely different models for the human evolution and dispersion in the Americas. For example, while most craniometrical studies report high morphological diversity among late Holocene populations of the Americas, the majority of molecular studies depict the lowest global values of genetic intra-population variation in the continent. These discrepancies resulted in different models, ranging between one and four waves of dispersion, defended for the settlement of the continent. Unfortunately, there are only a few research programs that currently aim to take on the challenge of integrating multiple sources of evidence, given the degree of academic specialization required to handle each data type. The crucial step to solve this limitation will be overcome only when an integrated framework for both genetic and non-genetic data is adopted to study biological diversity in the past. This symposium aims to bring together researchers working in the Americas that express similar concerns. We expect to create a stimulating environment for discussing the challenges and limitations with data integration with experts on the field that will promote enhanced and more accurate explanations for the origin and diversification of human populations in the Americas.
