their limits they either became non-viable or reverted to the original wild stock. The pigeon was always a pigeon no matter how far Darwin pushed the breeding.
Adoptive variation or microevolution among species is perfectly natural. Evolutionary transition from species to species (macroevolution) has never been found. Where have I observed this? I have read countless books dealing with evolution, paleontology, geology, zoology, biology, biochemistry, genetics, statistics, etcetera. Lately I've been concentrating on the books of Charles Darwin, Richard Dawkins, Stephan Jay Gould, and Neils Eldredge. They are the pillars of English and American evolutionary thought. As I am writing this, I have a dozen of their books scattered on the floor. I will be unorthodox and underline the titles of all of the books which I am quoting.
Darwin was dismayed by the fact that all leading paleontologists of his time disagreed with his ideas because the fossil record did not support gradual evolution. In fact, it showed just the opposite. Darwin also knew of the Cambrian explosion and the problems it would cause for his ideas.
Darwin writes in The Origin of the Species, "Why is not every geological formation full of intermediate links. Geology does not reveal any such finely-graduated chain; and this is the most obvious and serious objection against the theory." Darwin says,"Ifwe confine our attention to anyone formation it becomes more difficult to understand why we do not find closely graduated varieties between species." DarWin laments, " ... the abrupt and sudden appearance of whole groups of species has been urged by paleontologists Agassiz, Pictet, and Sedgwick as a fatal objection to my theory." Darwin cries out, " ... some of the difficulties are so serious that to this day I can hardly reflect on them without being staggered ... Why, if species have descended from other species by fine graduations, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion, instead of the species being, as we see them, well defined?"
I would recommend The Origin of the Species to anyone. The book consists of fifteen chapters. The titles of chapters 6, 7, 10, and 15 are as follows: Difficulties of the Theory; Miscellaneous Objections to the Theory of Natural Selection; On the Imperfection of the Geological Record; Recapitulation and Conclusion. Half of chapter 15 is dealing with the objections.
What other naturalist is so honest? No one is. Four of the fifteen chapters list countless objections to his own theory. It takes a great man to say, that he is proposing a theory but be careful - observation does not support it. Such as his remark in chapter 6, "But if we compare species, where they intermingle, they are generally as absolutely distinct from each other in every detail of structure."
Darwin knew that the rocks of the earth had not been explored exhaustively at his time, although many great naturalists had done their best to find fossils. He hoped that as more rocks were explored in all lands that the intermediate links would appear. Darwin's hopes have been crushed by the huge amount of Cambrian fossils that have been found throughout the world. The Cambrian explosion was a massive creation of all animal
