MrBayes

MrBayes is a program for doing Bayesian phylogenetic analysis including phylogenetic reconstruction. Bayesian inference of phylogeny is based on the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem. The posterior probability distribution of trees is often impossible to calculate analytically; instead, MrBayes uses a simulation technique called Markov Chain Monte Carlo (MCMC) to approximate the posterior probabilities of trees.
