Phylogenies are a fundamental tool for organizing our knowledge of the biological diversity we observe on our planet. But how exactly do we understand and use these devices? Tree diagrams have been ...

We derive a Markov chain to sample from the posterior distribution for a phylogenetic tree given sequence information from the corresponding set of organisms, a stochastic model for these data, and a ...

The composite tree is based on work from many different laboratories and is summarized elswhere; no single data set supports all branches. Polytomies indicate uncertainty in the branching order ...
