Curriculum Vitae

Josh Marshack

Assistant Professor

Joshua Marshack is a biological anthropologist who uses our closest living relatives, the great apes, as a jumping-off point to study the evolution of social behavior, elucidate the origins of status changes in humans, and challenge biological determinism and scientific racism. He has published on the social behavior and ecology of wild savanna chimpanzees, as well as on the evolution of lethal aggression. He enjoys working with students seeking answers to big questions about the past to be better prepared to shape our future.

Marshack’s research centers on chimpanzee and bonobo behavioral ecology, specifically the processes by which social thresholds are breached and relationships re-shaped. He has conducted fieldwork in the Republic of Senegal, at a site called Fongoli, and is looking forward to forthcoming projects at the Ape Cognition and Conservation Initiative in Des Moines, Iowa. Focusing on the way social order is changed, maintained, and subverted in the genus Pan, he hopes to learn what light these socio-spatial patterns shed on the origins of status transitions in humans. Exploring the effects of habitat disturbance on social instability and lethal aggression, he seeks to apply his research to improving primate conservation.

Through research and teaching interests extending beyond environmental sustainability and animal behavior, he is interested in tracing the processes by which societies naturalize various inequities, in the process obscuring their causes.

As a black, “mixed-race” and multi-cultural scholar, Marshack prioritizes analyzing topics from multiple perspectives, and asks students to explore a range of means in sharing their research and analysis. In his classes, activities and projects have included observational data collection at zoos and on farms, investigating nonhuman primate and human adaptations through laboratory sessions, archival and museum research on the history of scientific racism, and podcast and infographic production.

In today’s economic climate, students may find themselves switching careers several times over the course of their lives. For this, a liberal arts education can be invaluable. Anthropology, as both a social and biological science, can model the necessary flexibility. With courses grounded on experiential and place-based learning, Grinnell’s Department of Anthropology fosters intellectual diversity, social justice, and critical and creative discourse.

Marshack’s courses include: Anthropological Inquiries: Human Natures (a four-field introductory course); Human Evolution; Primate Behavior and Taxonomy; War, Peace, and Human Natures; and Biological Determinism and the Myth of Race.
