It is a little known fact that some of Charles Darwin's strongest initial objectors to his theory of natural evolution were palaeontologists. They claimed that if macro evolution were a fact, there would have to be millions of fossils of the intermediate varieties of species. Tons of species constantly evolving, should be tons of their leftover fossils, correct?
No. According to Zoologist Mark Ridley: "The fossil record of evolutionary change within single evolutionary lineages is very poor. If evolution is true, species originate through changes of ancestral species: one might expect to be able to see this in the fossil record. In fact it can rarely be seen. In 1859 Darwin could not cite a single example"(1).
But Darwin's time was years ago...so certainly today we would have better record of this happening, right? Palaeontologist David Raup of the Field Museum of Natural History said: "We are now 120 years after Darwin and the knowledge of the fossil record has been greatly expanded. We now have a quarter of a million fossil species, but the situation hasn't changed much. The record of evolution is still surprisingly jerky and, ironically, we have even fewer examples of evolutionary transition than we had in Darwin's time" (2, Italics mine).
For me, this serves as striking proof that we need be more diligent to test the claims of natural evolution, especially when we draw them out, such as with the fossil record of supposed intermediate species.
