Bill Nye on Evolution. Evidence. Fossil Horses. Hyracotherium and Equus. Copyright © 2001-2002 [Last Modified: January 3, 2002] n their attacks on evolution, creationists sometimes claim that the evolutionary family tree of the horse is flawed. And while this statement is hardly surprising given the source, some creationists also claim that the remains of Hyracotherium, the animal at the base of the horse sequence and more popularly known as eohippus, have been found along side the remains of modern horses.
This is hardly a problem for any modern theory of evolution, which allow ancestor and descendant species to exist side by side, but I have never heard the assertion from other than creationist or new age sources. The Search for the Original Claim Several websites make this claim, the majority of them referring to the book The Neck of the Giraffe (Hitching 1982). ...Eohippus fossils have been found in surface strata, along side two modern horses, Equus nevadensis and Equus occidentalis. Hitching gives no source for this. But where did Wysong get this idea? Ungulates. Girrafe Dissection.
