Downloading whole tree distributions

The phylogeny is available to download as either archives of complete trees (below) or by subsetting to a user provided set of species using the tool on the right.

There are four choices of class-wide tree distribution to choose from, each containing 10K trees, stored as zip archives of 1K trees each. Full details of each tree distribution are available in the supplementary material.

Full trees (9993 species), Hackett backbone
