PI Lecture with Max Wolf, “Fishy twin studies and the origin of personality differences”
I will discuss research on a powerful biological model system, the natural clonal fish Amazon molly. Mothers in this female-only species produce genetically identical offspring, allowing us to employ an experimental twin study approach to address some of the most fundamental questions associated with behaviour and the development of behaviour. Do twins separated directly after birth into identical environments develop personality differences? When and how do such differences develop? And how can this unique model system be used to understand the development of intelligent behaviour?
