“Open Tree of Life aims to construct a comprehensive, dynamic and digitally-available tree of life by synthesizing published phylogenetic trees along with taxonomic data. The project is a collaborative effort between 11 PIs across 10 institutions. Funding is from NSF AVAToL #1208809.

Browse the tree and leave feedback: Click on nodes to move through the tree, and click on nodes or edges to see more information about taxonomies and phylogenies that contain / support that node. If you have feedback about the relationships that you see, use the “Add Comment” button.

Contribute data: You can contribute to the synthetic tree by uploading trees through our curation interface. These can be trees from TreeBASE or trees uploaded from your computer. There will be a delay before uploaded trees appear in the synthetic tree. Up to summer 2015, the release cycle has been months between new versions of the synthetic tree, but this should shorten in the future.”
