Interesting thought, and it makes a great deal of sense, and I'm wondering what thoughts there might be on the development of lungs.
Will one day our brains evolve into something useful in a higher creature?
Lungs were developed out of necessity because of a lack of water for use with gills. The local lizard 101 was responsible for the manufacture and had they not been on strike evolution would not have taken millions of years.
