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.
