Few academic historians take an evolutionary perspective on the past, but this outcome was not inevitable. Leading eighteenth-century intellectuals often took evolutionary perspectives, but particularists largely discredited them in and after the 1780s. By the time Spencer and Darwin revived evolutionism in the 1850s, distinctive historical questions and methods were very well-established. Public intellectuals regularly called for Darwinian history, but almost no academics saw much to gain in it. Most twentieth-century social scientists became generalizers but not evolutionists, while most historians not only refused to engage in generalization of any kind but also criticized divisions of labor in which evolutionists would test theories against data generated by historians. Possibilities remain open for a properly evolutionary history, in which scholars trained as historians but asking evolutionary questions would work alongside those trained as evolutionists but analyzing historical data, but currently, this field's prospects depend too much on individual personalities and even luck.
