Evolutionism and recent findings

Last night i watched history channel on the recent discovery, this 43 million year female zoccola found intact and named Ida by the name of the daughter of the Anthropologist who found this fossil The most recent discovery before this one was Lucy 3.5 million years old fossil 40% only of the entire skeleton while Ida miraculously is 90% in spite of been 40 million years older. What do these discoveries mean? Lucy is an Ape who stands and walks on two legs, we know it from her pelvis and she represents a recent mutation from Monkeys, Ida on the other hand is a a mutation consisting in a change in the hand and in the lower teeth that will start anthropoids. No serious person doubts evolutionism but what a biologist said on TV was quite laughable. He compared evolutionism to physics and said that as we consider a fact that if we open our fingers and let an object fall it will fall to the ground because of gravitation, so facts like this one characterize evolutionism. This claim is quite irresponsible and things like that encourage Creationists dispute evolutionism . There are no facts like gravitation in Evolutionism: which is based on 1) uniformity with living organisms that mutate ( if we are part of nature we must be the outcome of some animal mutation, this is a hypotheses not a fact) 2) Lucy and Ida represent two case of possible evidence of mutation, but we need much more and a respectable theory of nature needs to make predictions and so far evolutionsim can't make prediction and maybe it will never do, mutations, whether they are random and unpredicatable, or connected to enviroment ( which should accomodate an infinte number of variables), mutations may be for ever unpredicted, just like volcanos eruptions are. Many people, including physicists , ignore what a scientific theory is.
