Jacob HarrisThe Consequences of Carnivory in Human Evolution: The intersection between pre-Early Stone Age butchery and technological evolution in modern hunter-gatherers

Thursday, April 25 - 4:30-5:45 p.m.
Location: SHESC 254

Jacob Harris, PhD

First, what is the spatiotemporal context associated with the origins of tool-mediated butchery in the hominin lineage and how common was it on the landscape? Second, how can the modern ethnographic record provide insight regarding the intersection of meat-eating, technological evolution, and a reliance on social learning? To address the first question, Harris will present the result of his dissertation research. He applied two Bayesian probability models, trained using experimental assemblages of bone surface modification, to the earliest fossil evidence of stone-mediated butchery in the hominin lineage from Ledi-Geraru, Ethiopia (2.82 Ma) and Dikika, Ethiopia (3.39 Ma). The results suggest early hominins were likely using unflaked stone to butcher animal carcasses by at least 3.39 Ma in Dikika and by 2.82 Ma in Ledi-Geraru. To address the second question, Harris will present the preliminary results from two ongoing studies among Hadza hunter-gatherers. His results suggest Hadza rely heavily upon cultural knowledge to facilitate the manufacture of their projectile technology and therefore the acquisition of meat. Further, although Hadza men’s activities are dominated by hunting, preliminary results suggest women may have a larger role in the acquisition of meat than previously thought.

Harris is interested in the complex interactions between an increased reliance on carnivory in the hominin lineage and the resulting downstream adaptations associated with human uniqueness. His current research focuses on the origin point of stone-mediated butchery in the hominin lineage through the construction of Bayesian probability models of bone surface modification. His paleoanthropological research focuses on landscape-scale taphonomy from Pre-Early Stone Age deposits of the Afar region, Ethiopia. Harris' research also includes a significant ethnoarchaeological component. He has developed several longitudinal studies among Hadza hunter-gatherers, exploring the intersection between hunting, technological evolution, and the importance of meat in the diets of modern hunter-gatherers. Currently, Harris is engaged in a post-doctoral collaboration with Brian Wood at the University of California, Los Angeles.
