Suppose there are three stratigraphic layers A,B, and C, in chronological order, with A the lowest in the pile and the oldest in age. There are no significant breaks in the pile that would suggest long periods of time in between them. Suppose we find a fossil animal in layer A, and a somewhat different one (but yet clearly related) fossil in C. Evolution predicts that there would be an intermediate fossil in layer B, if preserved. That prediction could be tested, could it not?
