Explore the fascinating world of cichlid fish evolution, speciation, and adaptation in this 55-minute lecture by Professor Axel Meyer at the Radcliffe Institute for Advanced Study. Delve into topics such as genome duplication, convergent evolution, and the incredible diversity of cichlids across various lakes. Examine unique adaptations like scale eating and large lips, and understand their roles in sexual selection and speciation. Investigate genetic mapping, hybridization, and the formation of new species without barriers to gene flow. Gain insights into Darwin's and Meier's definitions of species, and discover why fish may be more intriguing subjects of study than humans in the field of evolutionary biology.
