Rebecca Kilner, a Professor of Evolutionary Biology at the University of Cambridge and director of the Museum of Zoology, discusses her fascinating studies on burying beetles and their unique behaviors. She shares insights on how these beetles utilize mouse carcasses for nesting, shedding light on social behaviors and evolution. Rebecca also reflects on her journey from researching cuckoo birds to beetles, the challenges of motherhood in academia, and the importance of diversity in science, all while emphasizing the dynamic nature of evolutionary study.
Rebecca Kilner's research on burying beetles illustrates how social behaviors can significantly influence evolutionary processes and family dynamics among species.
The podcast emphasizes the necessity of diversity and inclusion in science, which enriches research and ensures broader perspectives in evolutionary studies.

The Intriguing Life of Burying Beetles
Burying beetles, particularly Nicrophorus vespilloides, exhibit remarkable social behaviors that are uncommon among insects, moving beyond the known eusocial structures. They engage in caring for their young in nests made from carrion, which poses a unique opportunity to explore parental investment and the dynamics between parents and offspring. These interactions reveal how social behaviors can influence evolutionary pressures and adaptations, making burying beetles an excellent subject for studying family cooperation and competition. By examining the intricacies of these beetles' social lives, researchers can deepen their understanding of how such complex behaviors evolve in animal species.
Evolutionary Biology and Social Behavior
The podcast discusses the critical role social interactions play in driving evolutionary change, particularly how cooperation among individuals can evolve in species traditionally perceived as self-serving. It poses intriguing questions about how complex behaviors evolve and subsequently influence natural selection and adaptability. By examining models such as cooperation in avian species like cuckoos and fairy wrens alongside burying beetles, insights can be gleaned about adaptive behaviors in varying ecological contexts. The findings underscore the importance of considering behavioral dynamics in the broader landscape of evolutionary biology.
Diversity in Scientific Exploration
The discussion touches on the significance of diversity and inclusion within scientific communities, emphasizing that diverse voices contribute to more thorough and accurate representations of scientific inquiry. The importance of recognizing contributions from underrepresented groups in academia highlights the need for broader perspectives in understanding the natural world. This emphasis on an inclusive scientific environment not only enriches research but also makes the process of discovery accessible and engaging for a wider audience. Ensuring a diverse scientific community ultimately benefits the integrity of science as a whole.
Personal Journey and Academic Growth
Rebecca Kilner’s personal journey combines a rich family heritage in science with formative experiences that shaped her academic path. Her move from bird studies to focus on burying beetles reflects an adaptability that showcases her commitment to research. The pivotal moments in her career, such as receiving a European Research Council grant while on maternity leave, illustrate the unpredictable yet transformative nature of scientific careers. Throughout her endeavors, Kilner remains devoted to advancing understanding in evolutionary biology while creating a positive impact through her leadership role at the Cambridge Museum of Zoology.
A fur-stripped mouse carcase might not sound like the cosiest of homes – but that’s where the burying beetle makes its nest; and where Rebecca Kilner has focused much of her research.
A Professor of Evolutionary Biology at the University of Cambridge, Rebecca’s work – initially with cuckoos, then more recently with the beetles – has shed invaluable light on the relationship between social behaviours and evolution.
She tells Jim Al-Khalili how the beetles’ helpfully swift generational churn and mouse-based parenting has allowed her team to study evolution in action, demonstrating for the first time what was previously just evolutionary theory.
