I can also quote Dr. Patterson:
“In several animal and plant groups, enough fossils are known to bridge the wide gaps between existing types. In mammals, for example, the gap between horses, asses and zebras (genus Equus) and their closest living relatives, the rhinoceroses and tapirs, is filled by an extensive series of fossils extending back sixty-million years to a small animal, Hyracotherium, which can only be distinguished from the rhinoceros-tapir group by one or two horse-like details of the skull. There are many other examples of fossil ‘missing links’, such as Archaeopteryx, the Jurassic bird which links birds with dinosaurs (Fig. 45), and Ichthyostega, the late Devonian amphibian which links land vertebrates and the extinct choanate (having internal nostrils) fishes. . .”

Regarding the fossil record of horses:
Niles Eldredge, biologist and paleontologist, co-author of Punctuated Equilibrium:
“I admit that a lot of that has gotten into the textbooks as though it were true. For instance, the most famous example still on exhibit downstairs (in the American Museum) is the exhibit on horse evolution prepared perhaps 50 years ago. That has been presented as literal truth in textbook after textbook. Now I think that that is lamentable, particularly because the people who propose these kinds of stories themselves may be aware of the speculative nature of some the stuff. But by the time it filters down to the textbooks, we’ve got science as truth and we’ve got a problem.”
George G. Simpson: “The uniform, continuous transformation of Hyracotherium into Equus, so dear to the hearts of generations of textbook writers, never happened in nature.”
Bruce McFadden, FL Museum of Natural History and U. of FL: “… over the years the fossil horses have been cited as prime example of orthogenesis [“straight-line evolution”] … it can no longer be considered a valid theory … we find that once a notion becomes part of accepted scientific knowledge, it is very difficult to modify or reject it.”
