7. The exhibition of the four grand types of the animal kingdom (radiate, molluscan, articulate, vertebrate), which characterizes the next stage of geological progress, is represented in _verses 20_ and _21_ as a creation of the lower animals—those that swarm in the waters, and the creeping and flying species of the land. Huxley, in his American Addresses, objects to this assigning of the origin of birds to the fifth day, and declares that terrestrial animals exist in lower strata than any form of bird,—birds appearing only in the Oölitic, or New Red Sandstone. But we reply that the fifth day is devoted to sea-productions, while land-productions belong to the sixth. Birds, according to the latest science, are sea-productions, not land-productions. They originated from Saurians, and were, at the first, flying lizards. There being but one mention of sea-productions, all these, birds included, are crowded into the fifth day. Thus Genesis anticipates the latest science. On the ancestry of birds, see Pop. Science Monthly, March, 1884:606; Baptist Magazine, 1877:505. 8. The introduction of mammals—viviparous species, which are eminent above all other vertebrates for a quality prophetic of a high moral purpose, that of suckling their young—is indicated in _verses 24_ and _25_ by the creation, on the sixth day, of cattle and beasts of prey. 9. Man, the first being of moral and intellectual qualities, and the first in whom the unity of the great design has full expression, forms in both the Mosaic and geologic record the last step of progress in creation (see _verses 26-31_). With Prof. Dana, we may say that “in this succession we observe not merely an order of events like that deduced from science; there is a system in the arrangement, and a far-reaching prophecy, to which philosophy could not have attained, however instructed.” See Dana, Manual of Geology, 741-746, and Bib. Sac., April, 1885:201-224. Richard Owen: “Man from the beginning of organisms was ideally present upon the earth”; see Owen, Anatomy of Vertebrates, 3:796; Louis Agassiz: “Man is the purpose toward which the whole animal creation tends from the first appearance of the first palæozoic fish.”
