  • Tracing the evolution of antievolution legislation.

    Maximum clade credibility tree from Bayesian tip-dating analysis of 67 policies. The SEAs originated by combining text from the AFAs with Ouachita Parish, Louisiana, policy text from 2006. Seven bills have a high posterior probability of being direct ancestors of the rest of the tradition (circles). The tips of branches reflect the bills' publication dates [except for the DI model bill (see text)]. The nodes (splitting events) represent copying events. The distance between a tip and a node is an inference about how much change occurred and how much time this took. When the node-to-tip distance is effectively zero, this indicates a high probability of direct ancestry. Tip labels indicate AFA or SEA, year, state, bill number (SB, senate bill; HB, house bill), and versions (a, b, or c, for legislative revisions; t or f, teachers or faculty targeted). Branch colors indicate the sciences targeted; mixed colors on a branch indicate uncertainty in the reconstruction. See SM for full details of analyses.
