Open Tree of Life constructs a comprehensive, dynamic and digitally-available tree of life by synthesizing published phylogenetic trees along with taxonomic data. The boxes below link to pages about different ways to use open tree.
Browse the synthetic tree and taxonomy. You can get information about the source of the information and provide feedback.
In addition to providing feedback on the tree and taxonomy, you can contribute to the synthetic tree by uploading trees through our curation interface.
We provide web-service APIs to make our data and tree estimates available for use by anyone. Click this box to see some examples of ways to use the Open Tree of Life.
