The great French biologist Jacques Monod would have turned 100 today. I am personally fond of him for having said, “What is true for E. coli is true for the elephant,” but he did much more than coin lovely phrases about microbes. His work on how genes switch on and off earned him a Nobel in 1965, and he also gave deep thought to the philosophy of biology, seeing it as the interplay of chance and necessity. Here’s a blog post from Larry Moran with more, and here’s Monod’s 1971 book, Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology
