As for the production and distribution of animals and plants, we have no objection to consider them on the Lamarckian principle. The germs of earth’s million vegetable varieties were and are doubtless scattered through the crust of the earth, to be modified by the elements which act upon the surface; they may exist in an infinitesimal manner, baffling to our senses and our ideas alike. The reptiles, fishes, and animals, probably owed their origin to _infusoria_ and a variety of changes following the law of development, and influenced by the sea or the sun. But between these and man—as we have already insisted—there is only an imperfect analogy, extremely helpless in this question of human derivation. That Lamarckian hypothesis—set forth so eloquently in the Vestiges of Creation—a work which, of a surety, belongs to Professor Nichol of Glasgow—answers very well for every thing but the man. Leave him out. Omit the part of Hamlet, and so play out the play. But man, the miraculous—that strange compound of dirt and divinity—will not be amenable to all this gradation—will not be put in a category and decided on, like a cactus or a kangaroo. He still remains apart—
The glory, jest, and riddle of the world.
Such are the considerations which lead us to reject the idea of a variety of pristine pairs. The arguments by which it is supported are many, but they are feeble. One of them is the fact, that, so far back as the records of the race have extended, the existing distinctions of it are discoverable. The most ancient Egyptian sculptures show the different features of the Negro and Ethiopian races, such as they appear at this day. These sculptures bear date nearly four thousand years ago; and it is concluded these heads had not time enough, since the beginning of the world, to be changed from a common type—seeing they have not since been changed in a lapse of time twice as long. They assume that our race has only been six thousand years on the globe. But that sort of argument is set aside by general consent. Chronological science is not among the truths which the Bible was intended to teach; with respect to the age of the world that venerable book is not historic nor authoritative. The most orthodox believers all over the world have admitted the demonstrations of geology; and we may safely conclude that our race has been roaming over the periphery of this planet for a longer period than that deduced by Usher from the Hebrew records. Philosophical science does not avail itself of such uncertainties as the world’s age is allowed to be. Again; it is argued by the doctors of development that a _pair_ could not naturally propagate a species. They keep their eyes very closely upon the habits of the lower animals. They do not consider what was contrary to nature in making the paragon of animals, only a little lower than the angels. The propagation of a species from a pair, seems a very conquerable sort of difficulty, compared with others, that lie along this field of our disquisition. Why should people strain so much at a gnat, after they have swallowed the dromedary?
