BEAST is a cross-platform program for Bayesian MCMC analysis of molecular sequences. It is orientated towards rooted, time-measured phylogenies inferred using strict or relaxed molecular clock models. It is intended both as a method of reconstructing phylogenies and as a framework for testing evolutionary hypotheses without conditioning on a single tree topology. BEAST uses MCMC to average over tree space, so that each tree is weighted proportional to its posterior probability. We include a simple to use user-interface program for setting up standard analyses and a suite of programs for analysing the results. There are three main areas of research for which the BEAUti/BEAST package is particularly applicable. These areas are species phylogenies for molecular dating, coalescent-based population genetics and measurably evolving populations (ancient DNA or time-stamped viral sequence data sets).
