“Fisher’s legacy in Darwinian biology”
Alan Grafen FRS, Department of Zoology, University of Oxford
The “Darwinian biology” of my title is what Darwin would have understood with his very limited knowledge of heredity and his focus on the improving power of natural selection on organismal design. Fisher's legacy includes specific contributions on the advantages of sexual over asexual reproduction, sexual selection, sex ratio theory and mimicry. He also
showed in what circumstances natural selection has fine-grained creative power; and provided a template model for proving mathematically that natural selection is an improving process and, crucially, proving what counts as improvement.
This talk was part of the Fisher in the 21st Century conference, held at Gonville & Caius College on April 21 and 22, 2022
