Alligators Hint at What Life May Have Been Like for Dinosaurs
April 17, 2009
When dinosaurs evolved, oxygen levels were much lower than they are now, so how did they cope? Curious to know what effects different oxygen levels would have on a modern dino relative, a team of U.S.-based scientists incubated alligator eggs at 12 percent, 21 percent and 30 percent oxygen levels. They found that the low oxygen conditions dramatically affected the embryo's development suggesting that dinosaurs' growth and metabolic patterns were drastically different from their modern relatives.
