The Open Tree of Life is an online phylogenetic tree of life – a collaborative effort, funded by the National Science Foundation. The first draft, including 2.3 million species, was released in September 2015. The Interactive graph allows the user to zoom in to taxonomic classifications, phylogenetic trees, and information about a node. Clicking on a species will return its source and reference taxonomy.
