What teeth can tell us about the life histories and behavior of extinct species (and cool science communication!) with Dr. Tesla Monson

This episode features a conversation with Dr. Tesla Monson, Assistant Professor in the Department of Anthropology at Western Washington University.
Tesla was in Japan visiting our own Dr. Susumu Tomiya to start some work with our collection of primate bones, so I asked Susumu to join us in the studio as well.
Tesla runs the Primate Evolution Lab at Western Washington University, and has conducted some fascinating research into how we can use bones and fossils and especially teeth to understand the “squishy parts” of our collective evolutionary past that don’t preserve, like the life history traits of an animal or its behavior.
Tesla tells us about some of her discoveries about correlated or patterned evolution that link tooth characteristics with other anatomical and physiological processes and allowed her and her colleagues to hypothesize about things like life history traits and behavior that aren’t preserved in the fossil record.
These include how dental patterns correlate with vitamin D delivery to infants in ancient populations of humans living in Arctic Beringia, or with prenatal growth rates and endocranial volume in catarrhine primates.
After hearing Tesla talk about these things I became a lot more interested in teeth myself, and what they can tell us about extinct species! But there’s a lot in this interview beyond teeth for anyone interested in evolution and the diversity of life, how scientists are often just like detectives, and just generally about being a whole person.
While discussing Tesla’s efforts in science communication, we talk about the phenomenon of imposter syndrome, which can affect anyone in any role but seems to be particularly common among academics, and especially in early career researchers. All three of us seemed to have something to say on the topic, as it’s an ongoing struggle for so many of us and any encouragement and open discussion about it may land with someone in need at the right time.
We close by looking at her current projects on inclusion in and out of science, such as

• her symposia in Integrative Human Evolution, geared toward early career researchers and interdisciplinarity,
• her involvement with the Bearded Ladies, who are out there to show the world that, to quote Tesla, “You don’t have to have a beard to be a scruffy paleontologist out in the field”,
• and her efforts to highlight the key roles played by historical women in Washington, which she calls Washington Women.

Some other things that come up in the interview include:

• Tesla’s study about teeth, prenatal growth rates and endocranial volume
• Tesla’s coauthored
