But your "mutating definition" is not the accepted idea of what a "mutation" is. Most of the creatures that have previously existed on this planet have passed into history. What remain mutated to survive to the present day. Whether they reached a successful mutation 200 million years ago, and remain the same since then, or 1000 years ago... mutation took place. Here is a recent mutation which I have observed myself, and has been noted in Natural History (or Smithsonian) Magazine: The Great Blue Heron Heretofore, Great Blue Herons could not tolerate close proximity of humans. They would abandon nests, would not breed, their numbers dwindled, they looked like the next "Whooping Crane" bird facing extinction. About 20 years ago, a remarkable thing happened: a mutation! A certain subset of Great Blue Herons became people tolerant! Their offspring were people tolerant. Twenty years ago, if you -looked- in the direction of a Blue Heron, and he could see your face, it flew away. Rapidly. The people-tolerant GBH's began rapidly filling all sorts of available niches. GBH population numbers are waaay up. I personally observed a GBH from forty feet away (unheard of in 1980!!) while it hunted gophers (another change!) at the Berkeley Marina. It successfully speared a gopher while under the observation (which the GBH ignored) of perhaps 40-50 people all within 100 yards of the bird. While I have personally seen the difference, it has been documented by bird experts as a true evolutionary change. To survive.
