After decades of the theory of evolution I would submit to you that in practice it has proved to be not falsifiable. I.e., every time it predicts something that doesn't pan out the way it predicted or some discovery makes it much less probable or even mathmatically impossible, the basic premise of evolution is never questioned.
But I gave you one specific example of how it is falsifiable (find widespread mammalian fossils in the Pre Cambrian strata). There are many others. The point is to be a scientific theory, it need only be CAPABLE of being falsified.

Because whatever errors there were in previous predictions, they were due to misinterpretation of details, not to flaws in the fundamental premises of the theory.
