Evolution as chance and necessity

Writing in Chance and NecessityMonod, Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology. Jacques Monod set out an eloquent account of evolution in terms of just two forces: the necessary laws of nature, and blind contingency. Darwin’s mechanism of natural selection fits neatly into this simple framework. The variation from generation to generation that gives rise to adaptations is explained as sheer chance (exemplified by quantum indeterminacyMonod, Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology. 111, 114.), and the differential survival of the better adapted species is inevitable, just as a projectile lofted with greater force is law-bound to reach a greater height. With this conceptual framework established, Monod can claim “chance alone is the source of every innovation, of all creation in the biosphere.”Monod, Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology. 112.

While Monod drew attention to the underlying simplicity of the processes driving evolution, other commentators have shown how these twin forces, in combination, can give rise to surprisingly complex phenomena.See Stuart A. Kauffman, At Home in the Universe: The Search for Laws of Self-Organization and Complexity (London: Penguin, 1996) 71-86.Biochemist Arthur Peacocke has critiqued Monod’s description pointing out that “the interplay between these principles is more subtle and complex than the simple dichotomies of the past would allow.”Peacocke in John Durant, ed., Darwinism and Divinity: Essays on Evolution and Religious Belief (Oxford: Blackwell, 1985) 116
