66 million years ago: asteroid and bird evolution | Dinosaurs' extinction | (Hindi)

Discover how a new study from the University of Michigan has unveiled the incredible story of how the asteroid impact that ended the reign of dinosaurs 66 million years ago also sparked significant evolutionary changes in the early ancestors of birds. This groundbreaking research provides new insights into how this mass extinction event influenced the genomic evolution of birds, leading to the incredible diversity seen in modern avian species. Published in the journal Science Advances, this study examined the evolutionary trajectory of all major bird groups and identified "genomic fossils" in bird DNA, revealing critical evolutionary steps. Learn how these changes within 5 million years of the extinction event resulted in the development of smaller body sizes and more altricial development patterns in birds. Join us as we explore the dramatic biological impacts of mass extinction events and gain a deeper understanding of the early evolutionary history of birds.
