DAVID: No, species had to appear with the anatomic changes first. All the fossils we have show jumps in the changes from earlier to later forms. With the new modifications the new species would then learn to use them. First anatomy, then more advanced speech.

> You say this great authority, but I do not follow your logic. Why should the anatomy not have changed as early humans strove to find new sounds with which to express new observations and thoughts? -You are missing the point of punctuated equilibrium. If the gaps are true and we have no other evidence, the new species arrives with the new speech apparatus and the new species then learns to use it. You are still accepting the gradualism of Darwin ,while I don't.
