EvolDir members may be familiar with the Open Tree of Life project https://tree.opentreeoflife.org/about/open-tree-of-life that curates a phylogeny of all life based on a synthesis of taxonomy and phylogenies (the "synthesis tree"). I have created an alternative viewer for the synthesis tree at https://iphylo.org/ott-viewer. The viewer is at the "proof of concept" stage, but I'm hoping it will be a useful starting point for anyone interested in exploring the Open Tree of Life synthesis tree. Feedback welcome.
