I am well aware that there is scarcely a single point discussed in this volume on which facts cannot be adduced, often apparently leading to conclusions directly opposite to those at which I have arrived. A fair result could be obtained only by fully stating and balancing the facts on both sides of each question, and this cannot possibly be done here. Although his theory could account for minor evolutionary change and the diversity of finches, Darwin knew that he had to virtually ignore the natural history of life on earth in order to maintain any hope of accounting for the origin of the phyla and the major disparity between arthropods and anthropologists.
Darwinian theory is in conflict with the most prominent features of earth's natural history.
First of all, geology does not provide the transitional forms Darwin's theory demands. The second conflict between Darwinism and natural history is the phenomenon of stasis. Geology reveals the stability of forms rather than their gradual transformation into substantially different body plans. Finally, the pervasive pattern of geologic succession is systematically backwards from that predicted by the theory. Darwinian theory predicts that the gradual accumulation of minor evolutionary change and the increasing diversity of the lower taxa should ultimately produce the profound differences among the major body plans and the disparity of the higher taxa.
