Reversals based on further evidence are part of science, inherently. Science shouldn't have a magical reputation, because it's not magic. Like all other means of explaining there material world, it's guesswork. There only difference is that science is guesswork with systematic effort to find holes in the guesses and improve them and reject there ones that don't work, while every other approach to explaining material phenomena had some form of guesswork and some method of closing which guesses to accept that is not based on what demonstrably works or fails.
