Give me an example of a spontaneous improvement

Evolution is not about improvement. It is about differential reproductive success. If you want a clear example of a life form that has evolved in our lifetimes, there is one clear example, a colony of bacteria in Japan that eats nylon. Nylon does not exist except where humans have made it.

Transitional species in progress are exemlpified by ring species.

Evolution is about improvement. We must get from bacteria to man via time and chance and random changes and survival of the fittest in 3 billion years. This is about improving species. We all know that if it happens gradually the fossil record should show it, if it happens in large bursts or big changes then those changes are much harder to explain. To say evolution is happening around us you must show an improvement in DNA that yields a better species not a minor change that is only an adaptation or hybridization.

Evolution is not about improvement.

Sure it is!!!

I've beentold MANY times in these threads that any changes that IMPROVE the organisms survival rate will be carried forward.
