Slow, cold reptile may breathe like energetic birds"

Live Science 2013

"Monitor lizards breathe by taking in air that flows through the lungs in a one-way loop -- a pattern of breathing that may have originated 270 million years ago in the ancestral group that gace rise to dinosaurs, and eventually alligators and birds, a new study finds."

"Air flows through lizard lungs in one direction, a finding that may prompt a rethink about how some species evolved following Earth's biggest mass extinction, a study said on Wednesday."

Spiegel Online 2013

"In birds and crocodiles oxygen flows in a kind of loop through the lungs. Now biologists have demonstrated such a breathing in lizards. THe technique could have originated 270 million years ago, the researchers suggest."

"Alligators breathe like birds due to a dinosaur ancestor they share in common, scientists have discovered."

Gators Dive With Flexible Air Tanks : Powell 2008 (314)_ 2 ScienceNOW

"A swimming alligator is an eerily quiet creature. The predator barely seems to twitch a muscle as it twists, turns, and glides toward its prey. This graceful movement may be guided by a rudder buried deep inside the reptile: flexible lungs that allow the gator to navigate by tipping its weight like a seesaw."

"Gotta Have Heart: Crocodilians Bypass Their Lungs To Improve Digestion"

"Crocodiles are among nature's most fearsome predators. When the opportunity arises, crocodilians will gorge, voluntarily consuming meals weighing 23% of their own body weight. This is analogous to a 130-pound woman eating, at one sitting, a hamburger weighing 30 pounds. New research on American alligators' circulation systems finds that crocodilians bypass their lungs to improve digestion."

"The Hidden Unity of Hearts" by Carl Zimmer

Brainerd 1997

"The blood circulation systems of certain air-breathing fishes and most reptiles appear to be primitive and inefficient. But there may well be good reason that they are designed the way they are, and the principles concerned could inform clinicians who treat heart disease."
