A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth‚ both living and extinct‚ have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive
