 The AnthroBiology Podcast sits down with biological anthropologists once or twice a month to learn about what they do and why it's rad. Want to know more about our evolutionary past? Or what your bones say about you? Maybe chimps are more your speed? If it's anthropology and it's about humans, we'll cover it.

    Dr. Erin Blankenship-Sefczek – How does developmental stress affect dental morphology?
    Sep 25 2025

    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.

  • Dr. Samantha Yaussy - What can frailty in skeletons from medieval London teach us about health?

    Dr. Samantha Yaussy - What can frailty in skeletons from medieval London teach us about health?
    Aug 28 2025
    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 longer lifespans than men. However, this doesn't seem to hold true in the populations she studies, which means the past may hold clues for improving health today. ------ Note: I feel pretty bad about dunking on The Pumpkin Spice Cafe. It was fine for what it was. I normally love "junk food" books, but this one just didn't do it for me, and that's ok. If you liked it, more power to you!

  • Dr. Habiba Chirchir - Why did humans evolve to have less robust skeletons?

    Dr. Habiba Chirchir - Why did humans evolve to have less robust skeletons?
    Jul 31 2025
    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 Dmitry Belyayev confused with Nikolai Vavilov. 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 Trofim Lysenko and based on Lamarckism. Also worth noting: The contributions of Lyudmila Trut who worked with Dr. Belyayev and continued running the study after his death.
