True. Even Kepler's Law had to be modified for Relativity because of one bad observation - Mercury.
Exactly! Far from being something to criticize science for, this is an example of science at its best. Newton's laws were accepted for hundreds of years until evidence was found to refute them. Dalton's indivisible atomic theory was the basis of chemistry for a long time until J.J. Thompson discovered the electron. This is the entire essence of science. One bad observation can completely kill a theory. The same is certainly true of evolution. Creationists state that since we never see a cow turn into a person, that evolution can't be true. Actually, if we DID see cows turn into people, that would be an observation that would falsify evolution. Evolution predicts that large changes should not occur, but that many small changes can build up to produce large varieties of life. This is just one, admittedly unlikely, example of a prediction that could result in the falsification of evolution. The existence of such falifiablilty is what makes evolution a science. What falsifiable predictions does creationism make?
