It is not evolution. The peppered moth is a powerful example of evolution. But prof, both are merely varieties of the same species, Biston betularia. Then there are resistant flies and bacteria. But prof, the flies are still flies and the bacteria have not switched species either.
Natural selection operates by changing one little part and later another.
All are slow, gradual, random changes. But prof, the principle of syntropy requires that everything must be in place instantly, or the organism cannot survive more than a few moments. The liver could not wait millions of years for the heart to be invented. The very fact that different species exist is the best proof that natural selection must have produced them. There should be no distinct species at all.
