There should be no evidence of any gradual change from one kind to another. Before going any further, it is important to establish one other point. Neither theory, creation or evolution, can be proven in the laboratory. Evolution requires tens of millions of years for any observable changes to occur. It is intuitively evident that it is not possible to conduct an experiment over such a vast time period.
Creation has a problem of even greater magnitude.
For creation to be true, it must be proven that it occured through divine intervention. This is a major obstacle for the theory. Again, it is impossible to perform any such experiment in the lab- oratory. We now have a dilemma because neither of these two theories can be proven in a controlled situation. Here is where the fossil evidence will prove to be of such great importance.
