What battle? Evolution happened, and is still happening. Spoken by a christian conservative with a brain.
No, it never did happen. Science has shown quite well the impossibility of one species transforming itself into another. Genetics shows us the impossibility of a mutation spreading throughout a species. DNA shows us the impossibility of a new useful gene ever occurring. Natural selection is only a destroyer, it cannot create anything.
Just about everything which evolutionists claim would enable species to transform itself into another has been scientifically shown to be false.
