This project is an inter-disciplinary collaboration, and has been tackling these questions using an experimental approach. Our focus has been primarily on the process of specialization on a limited range of food resources, which occurred during the transition from plant gathering to cultivation.
We have been particularly interested in the impacts of rising atmospheric CO2 immediately before the origin of agriculture, and the ecological traits of food plants that made them amenable (or not) to cultivation, and subsequently to domestication. This ecological selection process has been a hot topic ever since Darwin’s work on the subject.
We have a long-standing collaborations in this work with Glynis Jones and Mark Rees.
We are looking to develop this area of research, and welcome enquiries from prospective students and postdocs – see Opportunities.
