There are a small number of as yet unobservable scientific theories. String theory is an obvious example. Evolution isn’t one of them.
This position wrt evolution would require that a couple of fallacies be accepted.
First would be the fallacy of equivocation. That is, equivocating what is currently observed (adaptation) into that which is not observed (macro-evolution). This is accomplished through the further fallacy of affirming the consequent, where P 'predicts' Q, Q is observed and P is then assumed.
Once again we see the multiplication of logical fallacies surrounding evolution. It is simply a consequence of and quite necessary to support that belief.
