Decoding cemeteries: A historian's guide to death symbolism, power structures, and tech in early American burial grounds
AnthroBiology Podcast
Ron Romano of Spirits Alive (a non-profit dedicated to preserving Eastern Cemetery and its history) joins the show to talk about gravestone symbolism, mortuary practices, cemetery organization and social status, and the evolution of gravestone creation in Eastern Cemetery of Portland, ME. Cemeteries reveal a lot about the people who made them -- how they think about death, life, and religion; social and economic hierarchies; changing technologies; what's important to them; what causes anxiety. Cemeteries are human-made spaces filled with our bodies and artifacts that we've created. They...

Dr. Wakefield & Dr. Neidich – Death in early New York mental health institutions
AnthroBiology Podcast
Dr. Wakefield (Northeast College) and Dr. Neidich (University of Missouri) joined the show to discuss their research on death in early New York mental health institutions and how it differed from the populations around them. Along the way, we talk about the history of mental health institutions in the United States and how differences in the amount and causes of death can illuminate what we care about as a society. Dr. Walker also worked on this project, but unfortunately was unable to join. Her collaborators wanted to make sure that her contributions were noted :) Recommendations ...

Keri Porter – What can head trauma tell us about violence in an emerging Bronze Age city? Plus: How to apply for grad school
AnthroBiology Podcast
Keri Porter, a PhD candidate at Notre Dame University, joins the show to discuss their research on patterns of violence in a Bronze Age urban center in the Southern Levant. They focus on cranial trauma and what it can reveal about humans attempting to live together along with what it might reveal about who suffers violence. They also share some excellent recommendations for how to think about grad school, whether or not to go, and tips for applying. Recommendations Martin, D.L., Harrod, R.P., & Pérez, V.R. (Eds.)

AnthroBiology Podcast
Dr. Maria Nieves-Cólon and Jamie Zolik join the show to discuss their ancient DNA research in San Luis de Cañete and what it can reveal about the historical population of the town specifically and the African diaspora in South America generally. They share some of the exciting ways they've forged a partnership with the community in order to carry out the work as ethically as possible.

Dr. Eric Shattuck – How do humans act when we get sick and why?
AnthroBiology Podcast
Dr. Eric Shattuck of Florida State University joins the show to discuss his research on sickness behavior. He wants to know how humans tend to act when they get sick and why they act that way.

Dr. Erin Blankenship-Sefczek – How does developmental stress affect dental morphology?
AnthroBiology Podcast
Summary Dr. Erin Blankenship-Sefczek of Creighton University joins the show to discuss her research examining the connection between developmental stress and accessory cusps in teeth. Her work focuses on the placement and appearance of extra cusps that occur with greater frequency among individuals who have suffered stress during key developmental periods in their lives. Recommendations Blankenship-Sefczek EC, Goodman AH, Hubbe M, Hunter JP, Guatelli-Steinberg D (2024) . PLOS ONE 19(6): e0305123. Bailey SE, Hublin J-J. [links to pdf of chapter] In:...

Dr. Samantha Yaussy - What can frailty in skeletons from medieval London teach us about health?
AnthroBiology Podcast
Dr. Samantha Yaussy of James Madison University joins the show to discuss her research on the how sex, socioeconomic status, and developmental stress and the intersectionality therein might interact to affect health outcomes in the past via the lens of frailty in skeletal remains primarily from medieval London. In this episode, we talked about the skeletal markers of frailty in human remains, understanding bias in research and samples, and intersectionality. As part of this, Dr. Yaussy highlighted the morbidity-mortality paradox -- women in modern contexts typically have worse health but...

Dr. Habiba Chirchir - Why did humans evolve to have less robust skeletons?
AnthroBiology Podcast
Dr. Habiba Chirchir of the Ohio State University joins the show to discuss her research into the skeletal gracilization of modern humans. She's trying to understand when and why our skeletons became less robust, and whether self-domestication may have played a role. ------------------ Note: Apparently I got confused with . Both geneticists worked in the Soviet Union, but Dr. Belyayev wasn't persecuted to the same extent as Vavilov. Vavilov, who based his work on Mendelian genetics, ultimately died in prison for daring to go against Stalin's favored genetic model created by and based...

Dr. David Orton – Rats in Europe and Zooarchaeology
AnthroBiology Podcast
Dr. David Orton of the University of York joins the show to discuss how he uses zooarchaeology (the study of animal remains in archaeological contexts) to understand the how rat and human populations interacted and affected each other over time in Europe. He gets into the spread of rats, the plague, using ancient DNA and isotopic analysis to analyze rats, and what rats can tell us about historic events.
