Bird lovers: do you love taxonomy?? This is a long article over 30pp. ...many millions of years have given birds time to evolve into some 11,000 species<https://www.popularmechanics.com/science/animals/a64626968/new-crocodile-species/>, and keeping track of all those species-not to mention their evolutionary history-can be quite the challenge. Luckily, scientists from the University of California Merced and Cornell Lab of Ornithology decided that challenge was one they wanted to meet and proceeded to pour over 262 studies related to 9,239 bird species published from 1990 to 2024. After combining additional data on the 1,800 or so species not included in these studies, the team formed a complete map of avian evolutionary history. The results of this work were detailed in the journal Proceedings of the National Academies of Science<https://www.pnas.org/doi/10.1073/pnas.2409658122>(PNAS) A complete and dynamic tree of birds | PNAS<https://www.pnas.org/doi/10.1073/pnas.2409658122> GAndersson St Paul
