Which, of course, it does both. You simply see fit to declare that
it does neither and ignore all areas where it succeeds in both
criteria. Science has seen dozens if not hundreds of individual
cases of reproductively-isolated species evolve from parent stock
both in the wild and in the lab. It also is falsifiable by thousands
of possible observations. Unfortunately for your side, none of those
observations have ever been made and hence, evolution is not
falsified. Creationism, on the other hand, has been soundly
falsified using the same criteria.
You can't have it both ways, Walter.
