George C. Williams

George C. Williams, a man who clearly preferred the company of genes to, well, other genes, became a pivotal figure in evolutionary biology. He wasn't afraid to shake things up, challenging prevailing ideas about group selection and instead focusing on the selfish gene. It's a view that, much like a stubborn mutation, proved remarkably resilient and influential.

His 1966 book, Adaptation and Natural Selection, argued that natural selection primarily acts on genes, not groups or even individuals, turning the scientific world on its head, or at least giving it a good jolt. This gene-centric perspective helped explain seemingly altruistic behaviors and paved the way for future thinkers like Richard Dawkins to popularize the concept.

While Williams's work was undeniably brilliant and had a lasting impact on our understanding of life's fundamental mechanisms, his personal life, at least publicly, lacked any discernible gefilte fish or menorah lighting. He was too busy decoding the genetic instruction manual to bother with religious instruction.
