If it be objected to this conclusion that absence of derivation in the Post-pliocene and Modern does not prove that it may not previously have occurred, the answer is, that if the evolutionist admits that for a very long period (and this the only one of which we have any certain knowledge, and the only one which concerns man) derivation has been suspended, he in effect abandons his position. It may, however, be objected that what I have above affirmed of species may be affirmed of varieties, which are admitted to be derived. For example, it may be said that the negro variety of man has existed unchanged from the earliest historic times. It is carious that those who so often urge this argument as an evidence of the great antiquity of man, and the slow development of races, do not see that it proves too much. If the negro has been the same identical negro as far back as we can trace him, then his origin must have been independent, and of the nature of a creation, or else his duration as a negro must have been indefinite. What it does prove is a fact equally obvious from the study of Post-pliocene molluscs and other fossils, namely, that new species tend rapidly to vary to the utmost extent of their possible limits, and then to remain stationary for an indefinite time. Whether this results from an innate yet limited power of expansion in the species, or from the relations between it and external influences, it is a fact inconsistent with the gradual evolution of new species. Hence we conclude that the recent origin of man, as revealed by geology, is, in connection with the above facts, an absolute bar to the doctrine of derivation.
A second datum furnished to this discussion by geology and zoology is the negative one that no link of connection is known between man and any preceding animal. If we gather his bones and his implements from the ancient gravel-beds and cave-earths, we do not find them associated with any creature near of kin, nor do we find any such creature in those rich Tertiary beds which have yielded so great harvests of mammalian bones. In the modern world we find nothing nearer to him than such anthropoid apes as the orangs and gorillas. But the apes, however nearly allied, cannot be the ancestors of man. If at all related to him by descent, they are his brethren or cousins, not his parents; for they must, on the evolutionist hypothesis, be themselves the terminal ends of distinct lines of derivation from previous forms.
This difficulty is not removed by an appeal to the imperfection of the geological record. So many animals contemporary with man are known, both at the beginning of his geological history and in the present world, that it would be more than marvellous if no very near relative had ere this time been discovered at one extreme or the other, or at some portion of the intervening ages. Further, all the animals contemporary with man in the Post-glacial period, so far as is known, are in the same case. Discoveries of this kind may, however, still be made, and we may give the evolutionist the benefit of the possibility. We may affirm, however, that in order to gain a substratum of fact for his doctrine, he must find somewhere in the later Tertiary period animals much nearer to man than are the present anthropoid apes.
This demand I make advisedly—first, because the animals in question must precede man in geological time; and secondly, because the apes, even if they preceded man, instead of being contemporary with him, are not near enough to fulfil the required conditions. What is the actual fact with regard to these animals, so confidently affirmed to resemble some not very remote ancestors of ours? Zoologically they are not varieties of the same species with man they are not species of the same genus, nor do they belong to genera of the same family, or even to families of the same order. These animals are at least ordinally distinct from us in those grades of groups in which naturalists arrange animals. I am well aware that an attempt has been made to group man, apes, and lemurs in one order of “Primates,” and thus to reduce their difference to the grade of the family; but as pat by its latest and perhaps most able advocate, the attempt is a decided failure. One has only to read the concluding chapter of Huxley’s new book on the anatomy of the vertebrates to be persuaded of this, more especially if we can take into consideration, in addition to the many differences indicated, others which exist but are not mentioned by the author. Ordinal distinctions among animals are mainly dependent on grade or rank, and are not to be broken down by obscure resemblances of internal anatomy, having no relation to this point, but to physiological features of very secondary importance. Man must, on all grounds, rank much higher above the apes than they can do above any other order of mammals. Even if we refuse to recognise all higher grounds of classification, and condescend, with some great zoologists of our time, to regard nature with the eyes of mere anatomists, or in the same way that a brick-layer’s apprentice may be supposed to regard distinctions of architectural styles, we can arrive at no other conclusion. Let us imagine an anatomist, himself neither a man nor a monkey, but a being of some other grade, and altogether ignorant of the higher ends and powers of our species, to contemplate merely the skeleton of a man and that of an ape. He must necessarily deduce therefrom an ordinal distinction, even on the one ground of the correlations and modifications of structure implied in the erect position. It would indeed be sufficient for this purpose to consider merely the balancing of the skull on the neck, or the structure of the foot, and the consequences fairly deducible from either of them. Nay, were such imaginary anatomist a derivationist, and ignorant of the geological date of his specimens, and as careless of the differences in respect to brain as some of his human confrères, he might, referring to the loss specialised condition of man’s teeth and foot, conclude, not that man is an improved ape, but that the ape is a specialised and improved man. He would be obliged, however, even on this hypothesis, to admit that there must be a host of missing links. Nor would these be supplied by the study of the living races of men, because these want even specific distinctness, and differ from the apes essentially in those points on which an ordinal distinction can be fairly based.
This isolated position of man throughout the whole period of his history, grows in importance the more that it is studied, and can scarcely be the result of any accident of defective preservation of intermediate forms. In the meantime, when taken in connection with, the fact previously stated, that man is equally isolated when he first appears on the stage, it deprives evolution, as applied to our species, of any precise scientific basis, whether zoological or geological.
I do not attach any importance whatever, in this connection, to the likeness in type or plan between man and other mammals. Evolutionists are in the habit of taking for granted that this implies derivation, and of reasoning as if the fact that the human skeleton is constructed on the same principles as that of an ape or a dog, must have some connection with a common ancestry of these animals. This is, however, as is usual with them, begging the question. Creation, as well as evolution, admits of similarity of plan. When Stephenson constructed a locomotive, he availed himself of the principles and of many of the contrivances of previous engines; but this does not imply that he took a mine-engine, or a marine-engine, and converted it into a railroad-engine. Type or plan, whether in nature or art, may imply merely a mental evolution of ideas in the maker, not a derivation of one object from another.
But while man is related in his type of structure to the higher animals, his contemporaries, it is undeniable that there are certain points in which he constitutes a new type; and if this consideration were properly weighed, I believe it would induce zoologists, notwithstanding the proverbial humility of the true man of science, to consider themselves much more widely separated from the brutes than even by the ordinal distinction above referred to. I would state this view of the matter thus:—It is in the lower animals a law that the bodily frame is provided with all necessary means of defence and attack, and with all necessary protection against external influences and assailants. In a very few cases, we have partial exceptions to this. A hermit-crab, for instance, has the hinder part of its body unprotected; and has, instead of armour, the instinct of using the cast-off shells of molluscs; yet even this animal has the usual strong claws of a crustacean, for defence in front. There are only a very few animals in which instinct thus takes the place of physical contrivances for defence or attack, and in these we find merely the usual unvarying instincts of the irrational animal. But in man, that which is the rare exception in all other animals, becomes the rule. He has no means of escape from danger, compared with those enjoyed by other animals no defensive armour, no natural protection from cold or heat, no effective weapons for attacking other animals. These disabilities would make him the most helpless of creatures, especially when taken in connection with his slow growth and long immaturity. His safety and his dominion over other animals, are secured by entirely new means, constituting a “new departure” in creation. Contrivance and inventive power, enabling him to utilise the objects and forces of nature, replace in him the material powers bestowed on lower animals. Obviously the structure of the human being is related to this, and so related to it as to place man in a different category altogether from any other animal.
This consideration makes the derivation of man from brutes difficult to imagine. None of these latter appear even able to conceive or understand the modes of life and action of man. They do not need to attempt to emulate his powers, for they are themselves provided for in a different manner. They have no progressive nature like that of man. Their relations to things without are altogether limited to their structures and instincts. Man’s relations are limited only by his powers of knowing and understanding. How then is it possible to conceive of an animal which is, so to speak, a mere living machine, parting with the physical contrivances necessary to its existence, and assuming the new role of intelligence and free action?
This becomes still more striking if we adopt the view usually taken by evolutionists, that primitive man was a ferocious and carnivorous creature, warring with and overcoming the powerful animals of the Post-glacial period, and contending with the rigours of a severe climate. This could certainly not be inferred from his structure, interpreted by that of the lower animals, which would inevitably lead to the conclusion that he must Lave been a harmless and frugivorous creature, fitted to subsist only in the mildest climates, and where exempt from the attacks of the more powerful carnivorous animals. No one reasoning on the purely physical constitution of man, could infer that he might be a creature more powerful and ferocious than the lion or the tiger.
