Corning and Hines' assertions at the beginning of their article are correct. The political development literature is in “disarray.” There is dissensus on definitions and measures. The term ‘political evolution’ is seldom used in any technical or precise sense. Political scientists are mostly “unaware of the burgeoning literature… on the causal dynamics underlying the evolution of society in general and of politics and the state in particular,” and their “knowledge of pre-modern politics” does tend to be “sketchy.” The time is “ripe” (as always?) for “fresh approaches.” The introduction or reintroduction of “an evolutionary perspective” could be, depending on how it is defined, a “radical departure” from dominant frames of reference in political science.
