Picking up an ordinary text-book in zoology, we read: “The earliest member of the _series directly leading up to the horse_ was eohippus, an older eocene form about as large as a fox, which had four well-developed toes and the rudiments of a fifth on each forefoot, and three toes behind. In later eocene beds appeared an animal of similar size, but with only four toes in front and three behind. In newer beds, i.e., lower miocene, are found the remains of mesohippus, which was as large as a sheep and had three toes and the splint of another in each forefoot.... The succeeding forms were still more horse-like.”[186] Next they find a donkey-like animal, and later “a true equus, as large as the existing horse, appears just above the horizon, and the series is complete.”[187] If the horse tribe has evolved from a fox-like animal, it is little wonder that men trace their origin to the monkey tribe; but those who wish God’s character, take by faith the statement that “in the image of God created He him.” Such theories form the basis for the generally adopted classification of the entire vegetable and animal worlds. Christian education demands new text-books, based upon the truths of God’s Word. [Sidenote: Dana on origin of species] From Dana, the recognized authority on geology, the following sentences are quoted: “Life commenced among plants, in _seaweeds_; and it ended in _palms_, _oaks_, _elms_, the _orange_, _rose_, etc. It commenced among animals in _lingulæ_ (mollusks standing on a stem like a plant), _crinoids_, _worms_, and _trilobites_, and probably earlier in the simple systemless protozoans; it ended in _man_.” For this development, he says, “Time is long.” In a paragraph on “Progress Always the Gradual Unfolding of a System,” are the words: “There were higher and lower species appearing through _all the ages_, but the successive populations were still, in their general range, of higher and higher grade; and thus the progress was ever upward. The type or plan of vegetation, and the four grand types or plans of animal life, the radiate, molluscan, articulate, and vertebrate, were each displayed under multitudes of tribes and species, _rising in rank with the progress of time_.... Its progress should be, _as zoological history attests, a development, an unfolding, an evolution_.” In the study of this evolution in animal life, he says, “The progress in the system of life is a progress in cephalization,” and he gives several illustrations, as the passage from tadpole to frog; from lobster to crab, from worm to insect, etc. Such teachers speak always of the evolution from the lower to the higher forms of life, but leave retrogression entirely out of their reckoning.
