".Charles Pence's excellent new book provides a rich and detailed history that carefully inspects the traditional account of biometrics, plotting the emergence of statistical thinking in evolutionary theory. The author argues that Darwin informally made room for chance by conceptualizing natural selection not as a law but as a tendency, but a tendency that constrained sources of chance that might otherwise affect evolutionary outcomes. For Pence there is a tension here, which prevented a full commitment to a probabilistic theory, due to the deterministic philosophies of science in which Darwin was schooled. Nonetheless, Darwin created" --The Quarterly Review of Biology
