Macroevolutionary dynamics

Transient demography

Adaptation via maternal inheritance

In close collaboration with Rebecca Hoyle and Stuart Townley, I developed mathematical models and approaches to study the evolution of transgenerational effects. Any 'decision' in the parent generation has implications for the phenotype of the offspring with mathematical complications due to time lags between when information 'enters' the phenotype (e.g., being a first-born), and when natural selection operates (e.g., on the offspring of that first-born individual).

Our models of indirect genetic inheritance emphasise how the evolution of phenotypic means, variances and covariances are interwoven. For example, negative maternal effects that slow phenotypic evolution minimise variance around the optimum phenotype and thus maximise population mean fitness.
