The inherited lung structure of alligators and birds.

This BBC article written by BBC News science reporter Doreen Walton explains the new research on the lung structure of alligators and birds. Evolution and survival of the fittest. This report says that air flow in bird and alligator lungs is one-way and allows them to breathe in low oxygen environments. This breathing system has been passed down from their ancestors, the dinosaurs. I'd like to see a diagram of this lungs system.

This is right in time with the beginning of my first biology lecture and lab. I am attracting science based stories, last night Noah surprised me with the movie "Darwin." Charles Darwin was the beginning of evolution.
