Huge congratulations to Kirke who submitted her PhD today! Kirks PhD examined a whole range of questions related to the micro and macro evolutionary consequences of phenotypic plasticity. Much of her thesis focused on these questions in relation to cognition and learning but her results have wide ranging implications for the evolution of sociality as well as how plasticity shapes organismal form and function more generally. Importantly, we hope this work will form the foundation for a range of future work that examines the causes and consequences of cognition and learning in non-model systems such as lizards. It really is a wonderful read and we look forward to seeing what the reviewers think of it. Well done Kirke on a fantastic 4 years!
