This website provides a Bayesian inference of primate phylogeny, odd-toed and even-toed ungulates phylogeny, carnivorans phylogeny, and cetaceans phylogeny. In the near future, we may also include additional mammalian orders. The goal of the 10kTrees Project is to infer a set of phylogenetic trees from available data that is appropriate for comparative research. At this site, users can download a consensus tree, or they can download up to at least 10,000 trees drawn from the Markov chain sample and pruned to species of interest. Importantly, the 10kTrees Project is a work in progress and we envision regular updates to the dataset, trees and website.
