ABSTRACT
Sciences are characterized by their distinctive theories, the phenomena the theories explain and predict, and the central concepts, formulae, models, and research programs that these theories motivate. The revolutions in physical science that take their names from scientists, all the way from Newton to Einstein, began with the discovery of laws of nature, or else close approximations to them. So we might reasonably expect that the core of Darwin’s revolution that made biology a science is to be found in the laws that constitute his theory.
