The Moral and Intellectual Diversity of Races

Speaking of the origin of the domestic dog, Dr. Bachman, in his work on Unity of Races, p. 63, says: —

"Notwithstanding all these difficulties – and we confess we are not free from some doubts in regard to their identity (dog and wolf) – if we were called upon to decide on any wild species as the progenitor of our dogs, we would sooner fix upon the large wolf than on any other dog, hyena, or jackal," &c.

The doctor is unable, here at least (and we can point out many other cases), to "designate species;" and the recent investigations of Flourens, at the Jardin des Plantes, prove him wrong as regards the origin of the dog. The dog is not derived from the "large wolf," but, with it, produces hybrids, sterile after the third generation. The dog forms a genus apart.

We repeat, then, that in a large number of genera, the species cannot be separated by any anatomical characters, and that it is from their history alone naturalists have arrived at those minute divisions now generally received. We may, without the fear of contradiction, go a step further, and assert that several of the races of men are as widely separated in physical organization, physiological and psychological characters, as are the canidæ, equidæ, felines, elephants, bears and others. When the white races of Europe, the Mongols of Asia, the aborigines of America, the black races of Africa and Oceanica are placed beside each other, they are marked by stronger differences than are the species of the genera above named. It has been objected that these gaps are filled by intermediate links which make the chain complete from one extremity to the other. The admission of the fact does not invalidate our position, for we have shown elsewhere (see Types of Mankind) gradation is the law of nature. The extreme types, we have proven, have been distinct for more than 5000 years, and no existing causes during that time have transformed one type into another. The well-marked negro type, for example, stands face to face with the white type on the monuments of Egypt; and they differ more from each other than the dog and wolf, ass and Equis Hemionus, lion and tiger, &c. The hair and skin, the size and shape of head, the pelvis, the extremities, and other points, separate certain African and Oceanican negroes more widely than the above species. This will not be questioned, whatever difference of opinion may exist with regard to the permanency of these forms. In the language of Prof. Leidy, "the question to be determined is, whether the differences in the races of men are as permanent and of as much value as those which characterize species in the lower genera of animals." These races of men too are governed by the same laws of geographical distribution, as the species of the lower genera; they are found, as far back as history can trace them, as widely separated as possible, and surrounded by local Floræ and Faunæ.

VARIETIES

This term is very conveniently introduced to explain all the difficulties which embarrass this discussion. Dr. Bachman insists that all the races of men are mere varieties, and sustains the opinion by a repetition of those analogies which have been so often drawn from the animal kingdom by Prichard and his school. It is well known that those animals which have been domesticated undergo, in a few generations, very remarkable changes in color, form, size, habits, &c. For example, all the hogs, black, white, brown, gray, spotted, &c., now found scattered over the earth, have, it is said, their parentage in one pair of wild hogs. "This being admitted," says Dr. B. "we invite the advocates of plurality in the human species to show wherein these varieties are less striking than their eight (alluding to Agassiz) originally created nations." Again —

"And how has the discovery been made that all the permanent races are mere varieties, and not 'originally created' species, or 'primitive varieties?' Simply because the naturalists of Germany, finding that the original wild hog still exists in their forests, have, in a thousand instances, reclaimed them from the woods. By this means they have discovered that their descendants, after a few generations, lose their ferocity, assume all colors," &c.

The same reasoning is applied to horses, cattle, goats, sheep, &c., while many, if not most of the best naturalists of the day deny that we know anything of the origin of our domestic animals. Geoffroy St. Hilaire, in his work, just out, denies it in toto. We are, however, for the sake of argument, willing to admit all the examples, and all he claims with regard to the origin of endless varieties in domesticated animals.[199 - We are told that the pigs in one department of France are all black, in another, all white, and local causes are assigned! When I was a boy, my father introduced what was then called the China hog into the Union District, South Carolina; they were black, with white faces. On a visit to that district about twelve years ago, I found the whole country for 40 miles covered with them. On a visit one year ago, I found they had been supplanted entirely by other breeds of different colors: the old familiar type had disappeared.]

Let us, on the other hand, "invite the advocates of unity of the human species" to say when and where such varieties have sprung up in the human family. We not only have the written history of man for 2000 years, but his monumental history for 2000 more; and yet, while the naturalists of Germany are catching wild hogs, and recording in a thousand instances "after a few generations" these wonderful changes, no one has yet pointed out anything analogous in the human family; the porcupine family in England, a few spotted Mexicans, &c., do not meet the case; history records the origin of no permanent variety. No race of men has in the same country turned black, brown, gray, white, and spotted. The negroes in America have not in ten generations turned to all colors, though fully domesticated, like pigs and turkeys. The Jews in all countries for 2000 years are still Jews. The gypsies are everywhere still gypsies. In India, the different castes, of different colors, have been living together several thousand years, and are still distinct, &c. &c.

Nor does domestication affect all animals and fowls equally; compare the camel, ass, and deer, with the hog and dog; the Guinea fowl, pea fowl, and goose, with pigeons, turkeys, and common fowls. In fact, no one animal can be taken as an analogue for another: each has its own physiological laws; each is influenced differently and in different degrees by the same external influences. How, then, can an animal be taken as an analogue for man?

We have also abundant authority to show that all wild species do not present the same uniformity in external characters.

"All packs of American wolves usually consist of various shades of color, and varieties nearly black have been occasionally found in every part of the United States… In a gang of wolves which existed in Colleton District, South Carolina, a few years ago (sixteen of which were killed by hunters in eighteen months), we were informed that about one-fifth were black, and the others of every shade of color, from black to dusky gray and yellowish white." – Audubon & Bachman, 2d Amer. ed., vol. ii. pp. 130-1.

Speaking of the white American wolf, the same authors say: —

"Their gait and movements are precisely the same as those of the common dog, and their mode of copulating and number of young brought forth at a litter, are about the same." (It might have been added that their number of bones, teeth, whole anatomical structure are the same.) "The diversity of their size and color is remarkable, no two being quite alike."… "The wolves of the prairies … produce from six to eleven at a birth, of which there are very seldom two alike in color." —Op. cit., p. 159.

"The common American wolf, Richardson observes, sometimes shows remarkable diversity of color. On the banks of the Mackenzie River I saw five young wolves leaping and tumbling over each other with all the playfulness of the puppies of the domestic dog, and it is not improbable they were all of one litter. One of them was pied, another black, and the rest showed the colors of the common gray wolves."

The same diversity is seen in the prairie wolf, and naturalists have been much embarrassed in classifying the various wolves on account of colors, size, &c.

All this is independent of domestication, and shows the uncertainty of analogues; and still it is remarkable that though considerable variety exists in the native dogs of America in color and size, they do not run into the thousand grotesque forms seen on the old continent, where a much greater mixture exists. The dogs of America, like the aboriginal races of men, are comparatively uniform. In the East, where various races have come together, the men, like the dogs, present endless varieties, Egypt, Assyria, India, &c.

Let us suppose that one variety of hog had been discovered in Africa, one in Asia, one in Europe, one in Australia, another in America, as well marked as those Dr. B. describes; that these varieties had been transferred to other climates as have been Jews, gypsies, negroes, &c., and had remained for ages without change of form or color, would they be considered as distinct species or not? – can any one doubt? The rule must work both ways, or the argument falls to the ground.

In fact the Dr. himself makes admissions which fully refute his whole theory.

"Whilst," says he, "we are willing to allow some weight to the argument advanced by President Smyth, who endeavors to account for the varieties in man from the combined influences of three causes, 'climate, the state of society, and manner of living,' we are free to admit that it is impossible to account for the varieties in the human family from the causes which he has assigned."[200 - Op. cit., p. 177.]

The Dr. further admits, in the same work, that the races have been permanent since the time of the old Egyptian empire, and supposes that at some extremely remote time, of which we have no record, that "they were more susceptible of producing varieties than at a later period." These suppositions answer a very good purpose in theology, but do not meet the requirements of science.

HYBRIDITY

Having shown the insufficiency of all the other arguments in establishing the landmarks of species, let us now turn to those based on hybridity, which seems to be the last stronghold of the unity party. On this point hang all the difficulties of M. Gobineau, and had he been posted up to date here, his doubts would all have vanished. The last twelve months have added some very important facts to those previously published, and we shall, with as little detail as possible, present the subject in its newest light.

It is contended that when two animals of distinct species, or, in other words, of distinct origin, are bred together, they produce a hybrid which is infertile, or which at least becomes sterile in a few generations if preserved free from admixture with the parent stocks. It is assumed that unlimited prolificness is a certain test of community of origin.

We, on the contrary, contend that there is no abrupt line of demarcation; that no complete laws of hybridity have yet been established; that there is a regular gradation in the prolificness of the species, and that, according to the best lights we now possess, there is a continued series from perfect sterility to perfect prolificacy. The degrees may be expressed in the following language: —

1. That in which hybrids never reproduce; in other words, where the mixed progeny begins and ends with the first cross.

2. That in which the hybrids are incapable of producing inter se, but multiply by union with the parent stock.

3. That in which animals of unquestionably distinct species produce a progeny which are prolific inter se, but have a tendency to run out.

4. That which takes place between closely proximate species; among mankind, for example, and among those domestic animals most essential to human wants and happiness; here the prolificacy is unlimited.

It seems to be a law that in those genera where several or many species exist, there is a certain gradation which is shown in degrees of hybridity; some having greater affinity than others. Experiments are still wanting to make our knowledge perfect, but we know enough to establish our points.

There are many points we have not space to dwell on, as the relative influence of the male and female on the offspring; the tendency of one species to predominate over another; the tendency of types to "crop out" after lying dormant for many generations; the fact that in certain species some of the progeny take after one parent and some after the other, while in other cases the offspring presents a medium type, &c.

The genus Equus (Horse) comprises six species, of which three belong to Asia, and three to Africa. The Asiatic species are the Equus Caballus (Horse), Equus Hemionus (Dzigguetai), and Equus Asinus (Ass). Those of Africa are the Equus Zebra (Zebra), Equus Montanus (Daw), and the Equus Quaccha (Quagga). The horse and ass alone have been submitted to domestication from time immemorial; the others have remained wild.

It is well known that the horse and ass produce together an unprolific mule, and as these two species are the furthest removed from each other in their physical structure, Dr. Morton long since suggested that intermediate species bred together would show a higher degree of prolificness, and this prediction has been vindicated by experiments recently made in the Garden of Plants at Paris, where the ass and dzigguetai have been bred together for the last ten years. "What is very remarkable, these hybrids differ considerably from each other; some resemble much more closely the dzigguetai, others the ass." In regard to the product of the male dzigguetai and the jenny, Mr. Geoffroy St. Hilaire says:[201 - Domestication et Naturalization des Animaux utiles, par M. Isadore Geoffroy St. Hilaire, p. 71, Paris, 1854.]—

"Another fact, not less worthy of interest, is the fecundity, if not of all the mules, at least the firstborn among them; with regard to this, the fact is certain; he has produced several times with Jennies, and once with the female dzigguetai, the only one he has covered."[202 - Ibid.]

At a meeting of the "Société Zoologique d'Acclimation,"

M. Richard (du Cantal) "parle des essais de croisements de l'hémione avec l'anesse, et dit qu'ils ont donnè un mulet beaucoup plus ardent que l'âne. Il asserte que les produits de l'hémione avec l'âne, sont féconds, et que le métis, nommé Polka, à déja produit."

To what extent the prolificness of these two species will go is yet to be determined, and there is an unexplored field still open among the other species of this genus; it is highly probable that a gradation may be established from sterility, up to perfect prolificacy.

Not only do the female ass and the male onager breed together, but a male offspring of this cross, with a mare, produces an animal more docile than either parent, and combining the best physical qualities, such as strength, speed, &c.; whence the ancients preferred the onager to the ass, for the production of mules.[203 - Columbia, p. 135.] Mr. Gliddon, who lived upwards of twenty years in Egypt and other eastern countries, informs me this opinion is still prevalent in Egypt, and is acted upon more particularly in Arabia, Persia, &c., where the gour, or wild ass, still roams the desert. The zebra has also been several times crossed with the horse.

The genus canis contains a great many species, as domestic dogs, wolves, foxes, jackals, &c., and much discussion exists as to which are really species and which mere varieties. In this genus experiments in crossing have been carried a step further than in the Equidæ, but there is much yet to be done. All the species produce prolific offspring, but how far the prolificness might extend in each instance is not known; there is reason to believe that every grade would be found except that of absolute sterility which is seen in the offspring of the horse and ass.

The following facts are given by M. Flourens, and are the result of his own observations at the Jardin des Plantes.

"The hybrids of the dog and wolf are sterile after the third generation; those of the jackal and dog, are so after the fourth.

"Moreover, if one of these hybrids is bred with one of the primitive species, they soon return, completely and totally, to this species.

"My experiments on the crossing of species have given me opportunities of making a great many observations of this kind.

"The union of the dog and jackal produces a hybrid – a mixed animal, an animal partaking almost equally of the two, but in which, however, the type of the jackal predominates over that of the dog.

"I have remarked, in fact, in my experiments, that all types are not equally dominant and persistent. The type of the dog is more persistent than that of the wolf – that of the jackal more than that of the dog; that of the horse is less than that of the ass, &c. The hybrid of the dog and the wolf partakes more of the dog than the wolf; the hybrid of the jackal and dog, takes more after the jackal than dog; the hybrid of the horse and the ass partakes less of the horse than the ass; it has the ears, back, rump, voice of the ass; the horse neighs, the ass brays, and the mule brays like the ass, &c.

"The hybrid of the dog and jackal, then, partakes more of the jackal than dog – it has straight ears, hanging tail, does not bark, and is wild – it is more jackal than dog.

"So much for the first cross product of the dog with the jackal. I continue to unite, from generation to generation, the successive products with one of the two primitive stocks – with that of the dog, for example. The hybrid of the second generation does not yet bark, but has already the ears pendent at the ends, and is less savage. The hybrid of the third generation barks, has the ears pendent, the tail turned up, and is no longer wild. The hybrid of the fourth generation is entirely a dog.

"Four generations, then, have sufficed to re-establish one of the two primitive types – the type of the dog; and four generations suffice, also, to bring back the other type."[204 - De la Longevité Humaine, &c., par P. Flourens, Paris, 1855.]

From the foregoing facts, M. Flourens deduces, without assigning a reason, the following non sequitur: —

"Thus, then, either hybrids, born of the union of two distinct species, unite and soon become sterile, or they unite with one of the parent stocks, and soon return to this type – they in no case give what may be called a new species, that is to say, an intermediate durable species."[205 - M. Flourens here, perhaps, speaks too positively. The blood of the apparently lost species will show itself from time to time for many, if not endless generations.]
