A new study proposes that all dinosaurs shared a basic lung anatomy which may have given them an evolutionary edge Before getting to the ancient bones, however, it’s best to start with the present.

(CN) — In a new study, researchers say soaring birds like eagles, vultures and falcons that can glide effortlessly by flapping their wings only occasionally have evolved to use their lungs to aid in ...

Soaring birds — like osprey, eagles, falcons, even vultures — can stay aloft in the air seemingly forever, rarely flapping their wings. They glide along rising air currents in a way that has ...

Unlike the lungs of mammals, bird lungs do more than just breathe. An air-filled sac within the birds’ lungs is thought to increase the force the birds use to power flight muscles while soaring. Large ...

Like birds, green iguanas have unidirectional airflow in their lungs: When they breathe in or out, air flows in a one-way loop. “For years, people thought that the design evolved to meet the energetic ...

Dinosaurs were able to thrive in the oxygen-thin atmosphere of prehistoric Earth because they had super-efficient bird-like lungs which may have given them an advantage over their competition, ...

Alligators have a one-way path for breathing that is similar to birds’, new research shows. The findings, published in the Jan. 15 Science, could explain how dinosaurs’ ancestors rose to prominence.
