When you look at a sparrow hopping through your garden or watch a hawk soar overhead, you’re actually witnessing the last living descendants of dinosaurs in action. This isn’t some fantastical tale from science fiction – it’s one of the most remarkable stories of evolution that scientists have been piecing together through cutting-edge DNA analysis ...
For the first time, scientists have created a comprehensive evolutionary tree of all known bird species, synthesizing data from nearly 300 studies published between 1990 and 2024. This groundbreaking effort provides a unified framework for understanding bird evolution, taxonomy, and ecological relationships. How Scientists Built the Evolutionary Tree Researchers at the Cornell Lab of Ornithology ...
