Third, Morris again mischaracterizes evolutionary theory, as no one expects there to be some one unique mechanism of speciation. No Fossil Evidence. It used to be claimed that the best evidence for evolution was the fossil record, but the fact is that the billions of known fossils have not yet yielded a single unequivocal transitional form with transitional structures in the process of evolving. I suspect that no sequence will receive that label from Henry Morris no matter how clearly it might deserve it. But rather than dwell upon that, let's look at the quote from Stanley, which is illuminative of the level of Morris' intellectual honesty.
Transitional sequences can be, and mostly are, sequences across species.
Morris is attempting to make sweeping claims concerning a class of evidence while presenting a quote that deals with a small subset of evidence within that class. By hoping that you won't notice that it exists, that's how. The situation is worse than that, even. We have yet again another view of Morris bolstering a sweeping claim with a text byte that addresses only a minute fraction of the applicable evidence.
