Besides, we have with us yet the invertebrates that have not yet become vertebrates; marine animals that have not become amphibians; amphibians that have not become reptiles; reptiles that have become neither mammals nor birds, and a multitude of simians that have not become human, and are not moving toward man either in bodily form or intelligence or spirituality. We have the one-celled amoeba, the microscopic animals, and the lowest forms of animal life. If the great law of progress and advancement to higher forms has prevailed for so many million years, there should be none but the highest species. All should have reached the status of human beings and there should be none of the lower forms of life which are so abundant. Changes so radical and vast, stretching through so many ages, would require millions of connecting links. If reptiles became hairy mammals, we would expect fossils of thousands, if not millions, in the transition state. If some reptiles were changed into the 12,000 species of birds, we would expect countless fossils, part reptile, part bird. Only one is claimed, the archæopteryx (ancient bird), two specimens of which are known, which had a feathered tail, and which is only a slight modification of other birds. Many other birds have departed farther from the normal. There should be millions of fossils in the transition state if the theory were true. We have proven elsewhere that there is no credible evidence of links connecting man with the monkey family. There would have been many millions. We have shown, at length, that some of these great changes, especially the Evolution of man from the brute, could never have occurred. No one of these nine great advances was ever made, but it will suffice to examine now, as examples, two alleged great changes, reptiles into mammals, and reptiles into birds.
