Origins of bird species

The video explores the relationships among extant birds, focusing on their genealogy, ages, and the impact of genomic data on understanding these relationships. A novel finding is the division of birds into two groups, Columbia and Passera. The study also reveals that falcons are closely related to songbirds and that raptors have independent origins. The video emphasizes the importance of human stewardship in maintaining bird diversity.
