Reptiles' Breathing Hack Helped Birds Dominate the Air

The video explores the differences in breathing mechanisms between mammals and dinosaurs, focusing on the unidirectional airflow found in birds and some reptiles. This efficient breathing method allows continuous oxygen supply, enhancing flight capabilities. The evolution of this trait is discussed, with theories suggesting it may have developed during the Permian extinction to cope with low oxygen levels. Despite its unclear origins, unidirectional breathing provides significant advantages in high-altitude environments.
