A phylogeny, or evolutionary tree, depicts the inferred evolutionary relationships among a set of species as best we understand them. Scientific understanding of these evolutionary relationships is constantly shifting, so the underlying phylogeny database is designed to be updated with new information. For the first time ever, there will exist a visual and comprehensive resource that tells the evolutionary history of all birds—one that is consistent with the current avian taxonomy.
