The Greatest Show on Earth: The Evidence for Evolution

by Richard Dawkins

We should be positively worried if there were no intermediates so close to borderlines as to be difficult to classify. Indeed, on the evolutionary view, the conferring of discrete names should actually become impossible if only the fossil record were more complete. In one way, it is fortunate that fossils are so rare. If we had a continuous and unbroken fossil record, the granting of distinct names to species and genera would become impossible, or at least very problematical. It is a fair conclusion that the predominant source of discord among palaeoanthropologists – whether such and such a fossil belongs in this species/genus or that – is deeply and interestingly futile.

Id never thought of it this way before.
