Bayesian Evolutionary Analysis Sampling Trees (BEAST) is a program for Bayesian Markov Chain Monte Carlo (MCMC) analysis of molecular sequences. It is oriented towards rooted, time-measured phylogenies inferred using strict or relaxed molecular clock models. It can be used as a method of reconstructing phylogenies but is also a framework for testing evolutionary hypotheses without conditioning on a single tree topology.
PHYLIP (the PHYLogeny Inference Package) is a package of programs for inferring phylogenies (evolutionary trees). Methods that are available in the package include: parsimony, distance matrix, and likelihood methods, including bootstrapping and consensus trees. Input data types include molecular sequences, gene frequencies, restriction sites and fragments, distance matrices, and discrete characters.
