b. 1948
John Beatty is a philosopher of biology at the University of British Columbia known for his work on the nature and structure of evolutionary theory. He developed the influential evolutionary contingency thesis, which argues that most biological generalizations reflect historical contingencies rather than universal laws. His scholarship has shaped foundational debates about whether natural selection constitutes genuine scientific law and what explanatory work evolutionary theory can do.
