There are no known beneficial morphological mutations, only biochemical. Evolutionists know that the significance of these and similar mutations is in what they teach us about the developmental genetics, not the evolution, of organisms. There are countless examples of beneficial morphological and behavioral mutations in the technical literature. If he only would stop and think for a second, Wells would realize that he carries many of these mutations himself, which is why he looks different from other human beings. The evolutionists rejection of early hypotheses about a simple linear evolution of the horse lineage shows their commitment to a preconceived ideology.
Evolution is simply materialistic philosophy in disguise.
Wells himself acknowledges that the current view of the evolution of horses is very likely to be correct. This assumption has worked very well in practice, and Wells provides no reason to abandon it. The Piltdown man was a hoax, showing how easily evolutionists can be tricked in accepting evidence because it fits with their theory. Paleo-anthropology is not a science, but is really a form of story telling. More importantly, it was unmasked because it did not fit with the theory of evolution as applied to the new discoveries concerning the hominid fossil record.
