Having glanced at method and sources, I pass on to results. Some text-book must be consulted for the long list of pre-historic periods required for western Europe, not to mention the further complications caused by bringing in the remaining portions of the world. The stone-age, with its three great divisions, the eolithic (eôs, Greek for dawn, andlithos, stone) the palæolithic (pallæos, old), and the neolithic (neos, new), and their numerous subdivisions, comes first; then the age of copper and bronze; and then the early iron-age, which is about the limit of proto-history. Here I shall confine my remarks to Europe. I am not going far afield into such questions as: Who were the mound-builders of North America? And are the Calaveras skull and other remains found in the gold-bearing gravels of California to be reckoned amongst the earliest traces of man in the globe? Nor, again, must I pause to speculate whether the dark-stained lustrous flint implements discovered by Mr. Henry Balfour at a high level below the Victoria Falls, andpossibly deposited there by the river Zambezi before it had carved the present gorge in the solid basalt, prove that likewise in South Africa man was alive and busy untold thousands of years ago. Also, I shall here confine myself to the stone-age, because my object is chiefly to illustrate the long pedigree of the species from which we are all sprung.
The antiquity of man being my immediate theme, I can hardly avoid saying something about eoliths; though the subject is one that invariably sets pre-historians at each other's throats. There are eoliths and eoliths, however; and some of M. Rutot's Belgian examples are now-a-days almost reckoned respectable. Let us, nevertheless, inquire whether eoliths are not to be found nearer home. I can wish the reader no more delightful experience than to run down to Ightham in Kent, and pay a call on Mr. Benjamin Harrison. In the room above what used to be Mr. Harrison's grocery-store, eoliths beyond all count are on view, which he has managed to amass in his rare moments of leisure. As he lovingly cons the stones over, and shows off their points, his enthusiasm is likely to prove catching. But the visitor, we shall suppose, is sceptical. Very good; it is not far, though a stiffish pull, to Ash on the top of the North Downs. Hereabouts are Mr. Harrison'shunting-grounds. Over these stony tracts he has conducted Sir Joseph Prestwich and Sir John Evans, to convince the one authority, but not the other. Mark this pebbly drift of rusty-red colour spread irregularly along the fields, as if the relics of some ancient stream or flood. On the surface, if you are lucky, you may pick up an unquestionable palæolith of early type, with the rusty-red stain of the gravel over it to show that it has lain there for ages. But both on and below the surface, the gravel being perhaps from five to seven feet deep, another type of stone occurs, the so-called eolith. It is picked out from amongst ordinary stones partly because of its shape, and partly because of rough and much-worn chippings that suggest the hand of art or of nature, according to your turn of mind. Take one by itself, explains Mr. Harrison, and you will be sure to rank it as ordinary road-metal. But take a series together, and then, he urges, the sight of the same forms over and over again will persuade you in the end that human design, not aimless chance, has been at work here.
Well, I must leave Mr. Harrison to convert you into the friend or foe of his eoliths, and will merely add a word in regard to the probable age of these eolith-bearing gravels. Sir Joseph Prestwich has tried to work theproblem out. Now-a-days Kent and Sussex run eastwards in five more or less parallel ridges, not far short of 1,000 feet high, with deep valleys between. Formerly, however, no such valleys existed, and a great dome of chalk, some 2,500 feet high at its crown, perhaps, though others would say less, covered the whole country. That is why rivers like the Darenth and Medway cut clean through the North Downs and fall into the Thames, instead of flowing eastwards down the later valleys. They started to carve their channels in the soft chalk in the days gone by, when the watershed went north and south down the slopes of the great dome. And the red gravels with the eoliths in them, concludes Prestwich, must have come down the north slope whilst the dome was still intact; for they contain fragments of stone that hail from right across the present valleys. But, if the eoliths are man-made, then man presumably killed game and cut it up on top of the Wealden dome, how many years ago one trembles to think.
Let us next proceed to the subject of palæoliths. There is, at any rate, no doubt about them. Yet, rather more than half a century ago, when the Abbé Boucher de Perthes found palæoliths in the gravels of the Somme at Abbeville, and was the first torecognize them for what they are, there was no small scandal. Now-a-days, however, the world takes it as a matter of course that those lumpish, discoloured, and much-rolled stones, shaped something like a pear, which come from the high terraces deposited by the Ancient Thames, were once upon a time the weapons or tools of somebody who had plenty of muscle in his arm. Plenty of skill he had in his fingers, too; for to chip a flint-pebble along both faces, till it takes a more or less symmetrical and standard shape, is not so easy as it sounds. Hammer away yourself at such a pebble, and see what a mess you make of it. To go back for one moment to the subject of eoliths, we may fairly argue that experimental forms still ruder than the much-trimmed palæoliths of the early river-drift must exist somewhere, whether Mr. Harrison's eoliths are to be classed amongst them or not. Indeed, the Tasmanians of modern days carved their simple tools so roughly, that any one ignorant of their history might easily mistake the greater number for common pieces of stone. On the other hand, as we move on from the earlier to the later types of river-drift implements, we note how by degrees practice makes perfect. The forms grow ever more regular and refined, up to the point of time which hasbeen chosen as the limit for the first of the three main stages into which the vast palæolithic epoch has to be broken up. The man of the late St. Acheul period, as it is termed, was truly a great artist in his way. If you stare vacantly at his handiwork in a museum, you are likely to remain cold to its charm. But probe about in a gravel-bed till you have the good fortune to light on a masterpiece; tenderly smooth away with your fingers the dirt sticking to its surface, and bring to view the tapering or oval outline, the straight edge, the even and delicate chipping over both faces; then, wrapping it carefully in your handkerchief, take it home to wash, and feast till bedtime on the clean feel and shining mellow colour of what is hardly more an implement than a gem. They took a pride in their work, did the men of old; and, until you can learn to sympathize, you are no anthropologist.
During the succeeding main stage of the palæolithic epoch there was a decided set-back in the culture, as judged by the quality of the workmanship in flint. Those were the days of the Mousterians who dined off woolly rhinoceros in Jersey. Their stone implements, worked only on one face, are poor things by comparison with those of late St. Acheul days, though for a time degenerated forms of thelatter seem to have remained in use. What had happened? We can only guess. Probably something to do with the climate was at the bottom of this change for the worse. Thus M. Rutot believes that during the ice-age each big freeze was followed by an equally big flood, preceding each fresh return of milder weather. One of these floods, he thinks, must have drowned out the neat-fingered race of St. Acheul, and left the coast clear for the Mousterians with their coarser type of culture. Perhaps they were coarser in their physical type as well.[1]
[Footnote 1: Theirs was certainly the rather ape-like Neanderthal build. If, however, the skull found at Galley Hill, near Northfleet in Kent, amongst the gravels laid down by the Thames when it was about ninety feet above its present level, is of early palæolithic date, as some good authorities believe, there was a kind of man away back in the drift-period who had a fairly high forehead and moderate brow-ridges, and in general was a less brutal specimen of humanity than our Mousterian friend of the large grinders.]
To the credit of the Mousterians, however, must be set down the fact that they are associated with the habit of living in caves, and perhaps may even have started it; though some implements of the drift type occur in Le Moustier itself, as well as in other caves, such as the famous Kent's Cavern near Torquay. Climate, once more, has very possibly to answer for having thus driven man underground. Anyway, whether because theymust, or because they liked it, the Mousterians went on with their cave life during an immense space of time, making little progress; unless it were to learn gradually how to sharpen bones into implements. But caves and bones alike were to play a far more striking part in the days immediately to follow.
The third and last main stage of the palæolithic epoch developed by degrees into a golden age of art. But I cannot dwell on all its glories. I must pass by the beautiful work in flint; such as the thin blades of laurel-leaf pattern, fairly common in France but rare in England, belonging to the stage or type of culture known as the Solutrian (from Solutré in the department of Saône-et-Loire). I must also pass by the exquisite French examples of the carvings or engravings of bone and ivory; a single engraving of a horse's head, from the cave at Creswell Crags in Derbyshire, being all that England has to offer in this line. Any good museum can show you specimens or models of these delightful objects; whereas the things about which I am going to speak must remain hidden away for ever where their makers left them—I mean the paintings and engravings on the walls of the French and Spanish caves.
I invite you to accompany me in the spirit first of all to the cave of Gargas near Aventiron,under the shadow of the Pic du Midi in the High Pyrenees. Half-way up a hill, in the midst of a wilderness of rocky fragments, the relics of the ice-age, is a smallish hole, down which we clamber into a spacious but low-roofed grotto, stretching back five hundred feet or so into infinite darkness. Hard by the mouth, where the light of day freely enters, are the remains of a hearth, with bone-refuse and discarded implements mingling with the ashes to a considerable depth. A glance at these implements, for instance the small flint scraper with narrow high back and perpendicular chipping along the sides, is enough to show that the men who once warmed their fingers here were of the so-called Aurignacian type (Aurignac in the department of Haute Garonne, in southern France), that is to say, lived somewhere about the dawn of the third stage of the palæolithic epoch. Directly after their disappearance nature would seem to have sealed up the cave again until our time, so that we can study them here all by themselves.
Now let us take our lamps and explore the secrets of the interior. The icy torrents that hollowed it in the limestone have eaten away rounded alcoves along the sides. On the white surface of these, glazed over with a preserving film of stalactite, we at once noticethe outlines of many hands. Most of them left hands, showing that the Aurignacians tended to be right-handed, like ourselves, and dusted on the paint, black manganese or red ochre, between the outspread fingers in just way that we, too, would find convenient. Curiously enough, this practice of stencilling hands upon the walls of caves is in vogue amongst the Australian natives; though unfortunately, they keep the reason, if there is any deeper one than mere amusement, strictly to themselves. Like the Australians, again, and other rude peoples, these Aurignacians would appear to have been given to lopping off an occasional finger—from some religious motive, we may guess—to judge from the mutilated look of a good many of the handprints.
The use of paint is here limited to this class of wall-decoration. But a sharp flint makes an excellent graving tool; and the Aurignacian hunter is bent on reproducing by this means the forms of those game-animals about which he doubtless dreams night and day. His efforts in this direction, however, rather remind us of those of our infant-schools. Look at this bison. His snout is drawn sideways, but the horns branch out right and left as if in a full-face view. Again, our friend scamps details such as the legs. Sheer wantof skill, we may suspect, leads him to construct what is more like the symbol of something thought than the portrait of something seen. And so we wander farther and farther into the gloomy depths, adding ever new specimens to our pre-historic menagerie, including the rare find of a bird that looks uncommonly like the penguin. Mind, by the way, that you do not fall into that round hole in the floor. It is enormously deep; and more than forty cave-bears have left their skeletons at the bottom, amongst which your skeleton would be a little out of place.
Next day let us move off eastwards to the Little Pyrenees to see another cave, Niaux, high up in a valley scarred nearly up to the top by former glaciers. This cave is about a mile deep; and it will take you half a mile of awkward groping amongst boulders and stalactites, not to mention a choke in one part of the passage such as must puzzle a fat man, before the cavern becomes spacious, and you find yourself in the vast underground cathedral that pre-historic man has chosen for his picture-gallery. This was a later stock, that had in the meantime learnt how to draw to perfection. Consider the bold black and white of that portrait of a wild pony, with flowing mane and tail, glossy barrel, and jolly snub-nosed face. It is four or five feet across, andnot an inch of the work is out of scale. The same is true of nearly every one of the other fifty or more figures of game-animals. These artists could paint what they saw.
Yet they could paint up on the walls what they thought, too. There are likewise whole screeds of symbols waiting, perhaps waiting for ever, to be interpreted. The dots and lines and pothooks clearly belong to a system of picture-writing. Can we make out their meaning at all? Once in a way, perhaps. Note these marks looking like two different kinds of throwing-club; at any rate, there are Australian weapons not unlike them. To the left of them are a lot of dots in what look like patterns, amongst which we get twice over the scheme of one dot in the centre of a circle of others. Then, farther still to the left, comes the painted figure of a bison; or, to be more accurate, the front half is painted, the back being a piece of protruding rock that gives the effect of low relief. The bison is rearing back on its haunches, and there is a patch of red paint, like an open wound, just over the region of its heart. Let us try to read the riddle. It may well embody a charm that ran somewhat thus: "With these weapons, and by these encircling tactics, may we slay a fat bison, O ye powers of the dark!" Depend upon it, the men who went half a mileinto the bowels of a mountain, to paint things up on the walls, did not do so merely for fun. This is a very eerie place, and I daresay most of us would not like to spend the night there alone; though I know a pre-historian who did. In Australia, as we shall see later on, rock-paintings of game-animals, not so lifelike as these of the old days, but symbolic almost beyond all recognizing, form part of solemn ceremonies whereby good hunting is held to be secured. Something of the sort, then, we may suppose, took place ages ago in the cave of Niaux. So, indeed, it was a cathedral after a fashion; and, having in mind the carven pillars of stalactite, the curving alcoves and side-chapels, the shining white walls, and the dim ceiling that held in scorn our powerful lamps, I venture to question whether man has ever lifted up his heart in a grander one.
Space would fail me if I now sought to carry you off to the cave of Altamira, near Santander, in the north-west of Spain. Here you might see at its best a still later style of rock-painting, which deserts mere black and white for colour-shading of the most free description. Indeed, it is almost too free, in my judgment; for, though the control of the artist over his rude material is complete, he is inclined to turn his back on real life,forcing the animal forms into attitudes more striking than natural, and endowing their faces sometimes, as it seems to me, with almost human expressions. Whatever may be thought of the likelihood of these beasts being portrayed to look like men, certain it is that in the painted caves of this period the men almost invariably have animal heads, as if they were mythological beings, half animal and half human; or else—as perhaps is more probable—masked dancers. At one place, however—namely, in the rock shelter of Cogul near Lerida, on the Spanish side of the Pyrenees, we have a picture of a group of women dancers who are not masked, but attired in the style of the hour. They wear high hats or chignons, tight waists, and bell-shaped skirts. Really, considering that we thus have a contemporary fashion-plate, so to say, whilst there are likewise the numerous stencilled hands elsewhere on view, and even, as I have seen with my own eyes at Niaux in the sandy floor, hardened over with stalagmite, the actual print of a foot, we are brought very near to our palæolithic forerunners; though indefinite ages part them from us if we reckon by sheer time.
Before ending this chapter, I have still to make good a promise to say something aboutthe neolithic men of western Europe. These people often, though not always, polished their stone; the palæolithic folk did not. That is the distinguishing mark by which the world is pleased to go. It would be fatal to forget, however, that, with this trifling difference, go many others which testify more clearly to the contrast between the older and newer types of culture. Thus it has still to be proved that the palæolithic races ever used pottery, or that they domesticated animals—for instance, the fat ponies which they were so fond of eating; or that they planted crops. All these things did the neolithic peoples sooner or later; so that it would not be strange if palæolithic man withdrew in their favour, because he could not compete. Pre-history is at present almost silent concerning the manner of his passing. In a damp and draughty tunnel, however, called Mas d'Azil, in the south of France, where the river Arize still bores its way through a mountain, some palæolithic folk seem to have lingered on in a sad state of decay. The old sureness of touch in the matter of carving bone had left them. Again, their painting was confined to the adorning of certain pebbles with spots and lines, curious objects, that perhaps are not without analogy in Australia, whilst something like them cropsup again in the north of Scotland in what seems to be the early iron-age. Had the rest of the palæolithic men already followed the reindeer and other arctic animals towards the north-east? Or did the neolithic invasion, which came from the south, wipe out the lot? Or was there a commingling of stocks, and may some of us have a little dose of palæolithic blood, as we certainly have a large dose of neolithic? To all these questions it can only be replied that we do not yet know.
No more do we know half as much as we should like about fifty things relating to the small, dark, long-headed neolithic folk, with a language that has possibly left traces in the modern Basque, who spread over the west till they reached Great Britain—it probably was an island by this time—and erected the well-known long barrows and other monuments of a megalithic (great-stone) type; though not the round barrows, which are the work of a subsequent round-headed race of the bronze-age. Every day, however, the spade is adding to our knowledge. Besides, most of the ruder peoples of the modern world were at the neolithic stage of culture at the time of their discovery by Europeans. Hence the weapons, the household utensils, the pottery, the pile-dwellings, and so on, can be compared closely; and we have afresh instance of the way in which one branch of anthropology can aid another.
In pursuance of my plan, however, of merely pitching here and there on an illustrative point, I shall conclude by an excursion to Brandon, just on the Suffolk side of the border between that county and Norfolk. Here we can stand, as it were, with one foot in neolithic times and the other in the life of to-day. When Canon Greenwell, in 1870, explored in this neighbourhood one of the neolithic flint-mines known as Grime's Graves, he had to dig out the rubbish from a former funnel-shaped pit some forty feet deep. Down at this level, it appeared, the neolithic worker had found the layer of the best flint. This he quarried by means of narrow galleries in all directions. For a pick he used a red-deer's antler. In the British Museum is to be seen one of these with the miner's thumb-mark stamped on a piece of clay sticking to the handle. His lamp was a cup of chalk. His ladder was probably a series of rough steps cut in the sides of the pit. As regards the use to which the material was put, a neolithic workshop was found just to the south of Grime's Graves. Here, scattered about on all sides, were the cores, the hammer-stones that broke them up, and knives, scrapers, borers, spear-heads and arrow-heads galore, in all stages of manufacture.
Well, now let us hie to Lingheath, not far off, and what do we find? A family of the name of Dyer carry on to-day exactly the same old method of mining. Their pits are of squarer shape than the neolithic ones, but otherwise similar. Their one-pronged pick retains the shape of the deer's antler. Their light is a candle stuck in a cup of chalk. And the ladder is just a series of ledges or, as they call them, "toes" in the wall, five feet apart and connected by foot-holes. The miner simply jerks his load, several hundredweight of flints, from ledge to ledge by the aid of his head, which he protects with something that neolithic man was probably without, namely, an old bowler hat. He even talks a language of his own. "Bubber-hutching on the sosh" is the term for sinking a pit on the slant, and, for all we can tell, may have a very ancient pedigree. And what becomes of the miner's output? It is sold by the "jag"—a jag being a pile just so high that when you stand on any side you can see the bottom flint on the other—to the knappers of Brandon. Any one of these—for instance, my friend Mr. Fred Snare—will, while you wait, break up a lump with a short round hammer into manageable pieces. Then, placing a "quarter" with his left hand the leather pad that covers his knee, he will, with an oblong hammer, strike off flake afterflake, perhaps 1,500 in a morning; and finally will work these up into sharp-edged squares to serve as gun-flints for the trade with native Africa. Alas! the palmy days of knapping gun-flints for the British Army will never return to Brandon. Still, there must have been trade depression in those parts at any time from the bronze-age up to the times of Brown Bess; for the strike-a-lights, still to be got at a penny each, can have barely kept the wolf from the door. And Mr. Snare is not merely an artisan but an artist. He has chipped out a flint ring, a feat which taxed the powers of the clever neolithic knappers of pre-dynastic Egypt; whilst with one of his own flint fishhooks he has taken a fine trout from the Little Ouse that runs by the town.
Thus there are things in old England that are older even than some of our friends wot. In that one county of Suffolk, for instance, the good flint—so rich in colour as it is, and so responsive to the hammer, at any rate if you get down to the lower layers or "sases," for instance, the floorstone, or the black smooth-stone that is generally below water-level—has served the needs of all the palæolithic periods, and of the neolithic age as well, and likewise of the modern Englishmen who fought with flintlocks at Waterloo, or still more recently took out tinder-boxes with them to the warin South Africa. And what does this stand for in terms of the antiquity of man? Thousands of years? We do not know exactly; but say rather hundreds of thousands of years.
CHAPTER III
There is a story about the British sailor who was asked to state what he understood by a Dago. "Dagoes," he replied, "is anything wot isn't our sort of chaps." In exactly the same way would an ancient Greek have explained what he meant by a "barbarian." When it takes this wholesale form we speak, not without reason, of race-prejudice. We may well wonder in the meantime how far this prejudice answers to something real. Race would certainly seem to be a fact that stares one in the face.
Stroll down any London street: you cannot go wrong about that Hindu student with features rather like ours but of a darker shade. The short dapper man with eyes a little aslant is no less unmistakably a Japanese. It takes but a slightly more practised eye to pick outthe German waiter, the French chauffeur, and the Italian vendor of ices. Lastly, when you have made yourself really good at the game, you will be scarcely more likely to confuse a small dark Welshman with a broad florid Yorkshireman than a retriever with a mastiff.
Yes, but remember that you are judging by the gross impression, not by the element of race or breed as distinguished from the rest. Here, you say, come a couple of our American cousins. Perhaps it is their speech that betrayeth them; or perhaps it is the general cut of their jib. If you were to go into their actual pedigrees, you would find that the one had a Scotch father and a mother from out of Dorset; whilst the other was partly Scandinavian and partly Spanish with a tincture of Jew. Yet to all intents and purposes they form one type. And, the more deeply you go into it, the more mixed we all of us turn out to be, when breed, and breed alone, is the subject of inquiry. Yet race, in the only sense that the word has for an anthropologist, means inherited breed, and nothing more or less—inherited breed, and all that it covers, whether bodily or mental features.
For race, let it not be forgotten, presumably extends to mind as well as to body. It is not merely skin-deep. Contrast the stoical Red Indian with the vivacious Negro; or thephlegmatic Dutchman with the passionate Italian. True, you say, but what about the influence of their various climates, or again of their different ideals of behaviour? Quite so. It is immensely difficult to separate the effects of the various factors. Yet surely the race-factor counts for something in the mental constitution. Any breeder of horses will tell you that neither the climate of Newmarket, nor careful training, nor any quantity of oats, nor anything else, will put racing mettle into cart-horse stock.
In what follows, then, I shall try to show just what the problem about the race-factor is, even if I have to trespass a little way into general biology in order to do so.[2] And I shall not attempt to conceal the difficulties relating to the race-problem. I know that the ordinary reader is supposed to prefer that all the thinking should be done beforehand, and merely the results submitted to him. But I cannot believe that he would find it edifying to look at half-a-dozen books upon the races of mankind, and find half-a-dozen accounts of their relationships, having scarcely a single statement in common. Far better face the fact that race still baffles us almost completely.Yet, breed is there; and, in its own time and in its own way, breed will out.
[Footnote 2: The reader is advised to consult also the more comprehensive study onEvolutionby Professors Geddes and Thomson in this series.]
Race or breed was a moment ago described as a factor in human nature. But to break up human nature into factors is something that we can do, or try to do, in thought only. In practice we can never succeed in doing anything of the kind. A machine such as a watch we can take to bits and then put together again. Even a chemical compound such as water we can resolve into oxygen and hydrogen and then reproduce out of its elements. But to dissect a living thing is to kill it once and for all. Life, as was said in the first chapter, is something unique, with the unique property of being able to evolve. As life evolves, that is to say changes, by being handed on from certain forms to certain other forms, a partial rigidity marks the process together with a partial plasticity. There is a stiffening, so to speak, that keeps the life-force up to a point true to its old direction; though, short of that limit, it is free to take a new line of its own. Race, then, stands for the stiffening in the evolutionary process. Just up to what point it goes in any given case we probably can never quite tell. Yet, if we could think our way anywhere near to that point in regard to man, I doubt not that we should eventually succeed in forging a fresh instrument forcontrolling the destinies of our species, an instrument perhaps more powerful than education itself—I mean, eugenics, the art of improving the human breed.
To see what race means when considered apart, let us first of all take your individual self, and ask how you would proceed to separate your inherited nature from the nature which you have acquired in the course of living your life. It is not easy. Suppose, however, that you had a twin brother born, if indeed that were possible, as like you as one pea is like another. An accident in childhood, however, has caused him to lose a leg. So he becomes a clerk, living a sedentary life in an office. You, on the other hand, with your two lusty legs to help you, become a postman, always on the run. Well, the two of you are now very different men in looks and habits. He is pale and you are brown. You play football and he sits at home reading. Nevertheless, any friend who knows you both intimately will discover fifty little things that bespeak in you the same underlying nature and bent. You are both, for instance, slightly colour-blind, and both inclined to fly into violent passions on occasion. That is your common inheritance peeping out—if, at least, your friend has really managed to make allowance for your common bringing-up, which might mainlyaccount for the passionateness, though hardly for the colour-blindness.
But now comes the great difficulty. Let us further suppose that you two twins marry wives who are also twins born as like as two peas; and each pair of you has a family. Which of the two batches of children will tend on the whole to have the stronger legs? Your legs are strong by use; your brother's are weak by disuse. But do use and disuse make any difference to the race? That is the theoretical question which, above all others, complicates and hampers our present-day attempts to understand heredity.
In technical language, this is the problem of use-inheritance, otherwise known as the inheritance of acquired characters. It is apt to seem obvious to the plain man that the effects of use and disuse are transmitted to offspring. So, too, thought Lamarck, who half a century before Darwin propounded a theory of the origin of species that was equally evolutionary in its way. Why does the giraffe have so long a neck? Lamarck thought it was because the giraffe had acquired a habit of stretching his neck out. Every time there was a bad season, the giraffes must all stretch up as high as ever they could towards the leafy tops of the trees; and the one that stretched up farthest survived, andhanded on the capacity for a like feat to his fortunate descendants. Now Darwin himself was ready to allow that use and disuse might have some influence on the offspring's inheritance; but he thought that this influence was small as compared with the influence of what, for want of a better term, he called spontaneous variation. Certain of his followers, however, who call themselves Neo-Darwinians, are ready to go one better. Led by the German biologist, Weismann, they would thrust the Lamarckians, with their hypothesis of use-inheritance, clean out of the field. Spontaneous variation, they assert, is all that is needed to prepare the way for the selection of the tall giraffe. It happened to be born that way. In other words, its parents had it in them to breed it so. This is not a theory that tells one anything positive. It is merely a caution to look away from use and disuse to another explanation of variation that is not yet forthcoming.
After all, the plain man must remember that the effects of use and disuse, which he seems to see everywhere about him, are mixed up with plenty of apparent instances to the contrary. He will smile, perhaps, when I tell him that Weismann cut off the tails of endless mice, and, breeding them together, found that tails invariably decorated the race as before.I remember hearing Mr. Bernard Shaw comment on this experiment. He was defending the Lamarckianism of Samuel Butler, who declared that our heredity was a kind of race-memory, a lapsed intelligence. "Why," said Mr. Shaw, "did the mice continue to grow tails? Because they never wanted to have them cut off." But men-folk are wont to shave off their beards because they want to have them off; and, amongst people more conservative in their habits than ourselves, such a custom may persist through numberless generations. Yet who ever observed the slightest signs of beardlessness being produced in this way? On the other hand, there are beardless as well as bearded races in the world; and, by crossing them, you could, doubtless, soon produce ups and downs in the razor-trade. Only, as Weismann's school would say, the required variation is in this case spontaneous, that is, comes entirely of its own accord.
Leaving the question of use-inheritance open, I pass on to say a word about variation as considered in itself and apart from this doubtful influence. Weismann holds, that organisms resulting from the union of two cells are more variable than those produced out of a single one. On this view, variation depends largely on the laws of the interaction of the dissimilar characters broughttogether in cell-union. But what are these laws? The best that can be said is that we are getting to know a little more about them every day. Amongst other lines of inquiry, the so-called Mendelian experiments promise to clear up much that is at present dark.
The development of the individual that results from such cell-union is no mere mixture or addition, but a process of selective organization. To put it very absurdly, one does not find a pair of two-legged parents having a child with legs as big as the two sets of legs together, or with four legs, two of them of one shape and two of another. In other words, of the possibilities contributed by the father and mother, some are taken and some are left in the case of any one child. Further, different children will represent different selections from amongst the germinal elements. Mendelism, by the way, is especially concerned to find out the law according to which the different types of organization are distributed between the offspring. Each child, meanwhile, is a unique individual, a living whole with an organization of its very own. This means that its constituent elements form a system. They stand to each other in relations of mutual support. In short, life is possible because there is balance.
This general state of balance, however, is able to go along with a lot of special balancings that seem largely independent of each other. It is important to remember this when we come a little later on to consider the instincts. All sorts of lesser systems prevail within the larger system represented by the individual organism. It is just as if within the state with its central government there were a number of county councils, municipal corporations, and so on, each of them enjoying a certain measure of self-government on its own account. Thus we can see in a very general way how it is that so much variation is possible. The selective organization, which from amongst the germinal elements precipitates ever so many and different forms of fresh life, is so loose and elastic that a working arrangement between the parts can be reached in all sorts of directions. The lesser systems are so far self-governing that they can be trusted to get along in almost any combination; though of course some combinations are naturally stronger and more stable than the rest, and hence tend to outlast them, or, as the phrase goes, to be preserved by natural selection.
It is time to take account of the principle of natural selection. We have done with the subject of variation. Whether use and disusehave helped to shape the fresh forms of life, or whether these are purely spontaneous combinations that have come into being on what we are pleased to call their own account, at any rate let us take them as given. What happens now? At this point begins the work of natural selection. Darwin's great achievement was to formulate this law; though it is only fair to add that it was discovered by A.R. Wallace at the same moment. Both of them get the first hint of it from Malthus. This English clergyman, writing about half a century earlier, had shown that the growth of population is apt very considerably to outstrip the development of food-supply; whereupon natural checks such as famine or war must, he argued, ruthlessly intervene so as to redress the balance. Applying these considerations to the plant and animal kingdoms at large, Darwin and Wallace perceived that, of the multitudinous forms of life thrust out upon the world to get a livelihood as best they could, a vast quantity must be weeded out. Moreover, since they vary exceedingly in their type of organization, it seemed reasonable to suppose that, of the competitors, those who were innately fitted to make the best of the ever-changing circumstances would outlive the rest. An appeal to the facts fully bore out this hypothesis. It must not, indeed, bethought that all the weeding out which goes on favours the fittest. Accidents will always happen. On the whole, however, the type that is most at home under the surrounding conditions, it may be because it is more complex, or it may be because it is of simpler organization, survives the rest.
Now to survive is to survive to breed. If you live to eighty, and have no children, you do not survive in the biological sense; whereas your neighbour who died at forty may survive in a numerous progeny. Natural selection is always in the last resort between individuals; because individuals are alone competent to breed. At the same time, the reason for the individual's survival may lie very largely outside him. Amongst the bees, for instance, a non-working type of insect survives to breed because the sterile workers do their duty by the hive. So, too, that other social animal, man, carries on the race by means of some whom others die childless in order to preserve. Nevertheless, breeding being a strictly individual and personal affair, there is always a risk lest a society, through spending its best too freely, end by recruiting its numbers from those in whom the engrained capacity to render social service is weakly developed. To rear a goodly family must always be the first duty of unselfish people; for otherwise thespirit of unselfishness can hardly be kept alive the world.
Enough about heredity as a condition of evolution. We return, with a better chance of distinguishing them, to the consideration of the special effects that it brings about. It was said just now that heredity is the stiffening in human nature, a stiffening bound up with a more or less considerable offset of plasticity. Now clearly it is in some sense true that the child's whole nature, its modicum of plasticity included, is handed on from its parents. Our business in this chapter, however, is on the whole to put out of our thoughts this plastic side of the inherited life-force. The more or less rigid, definite, systematized characters—these form the hereditary factor, the race. Now none of these are ever quite fixed. A certain measure of plasticity has to be counted in as part of their very nature. Even in the bee, with its highly definite instincts, there is a certain flexibility bound up with each of these; so that, for instance, the inborn faculty of building up the comb regularly is modified if the hive happens to be of an awkward shape. Yet, as compared with what remains over, the characters that we are able to distinguish as racial must show fixity. Unfortunately, habits show fixity too. Yet habits belong to the plastic side of our nature; for, in forming ahabit, we are plastic at the start, though hardly so once we have let ourselves go. Habits, then, must be discounted in our search for the hereditary bias in our lives. It is no use trying to disguise the difficulties attending an inquiry into race.
These difficulties notwithstanding, in the rest of this chapter let us consider a few of what are usually taken to be racial features of man. As before, the treatment must be illustrative; we cannot work through the list. Further, we must be content with a very rough division into bodily and mental features. Just at this point we shall find it very hard to say what is to be reckoned bodily and what mental. Leaving these niceties to the philosophers, however, let us go ahead as best we can.
Oh for an external race-mark about which there could be no mistake! That has always been a dream of the anthropologist; but it is a dream that shows no signs of coming true. All sorts of tests of this kind have been suggested. Cranium, cranial sutures, frontal process, nasal bones, eye, chin, jaws, wisdom teeth, hair, humerus, pelvis, the heart-line across the hand, calf, tibia, heel, colour, and even smell—all these external signs, as well as many more, have been thought, separatelyor together, to afford the crucial test of a man's pedigree. Clearly I cannot here cross-examine the entire crowd of claimants, were I even competent to do so. I shall, therefore, say a few words about two, and two only, namely, head-form and colour.
I believe that, if the plain man were to ask himself how, in walking down a London street, he distinguished one racial type from another, he would find that he chiefly went by colour. In a general way he knows how to make allowance for sunburn and get down to the native complexion underneath. But, if he went off presently to a museum and tried to apply his test to the pre-historic men on view there, it would fail for the simple reason that long ago they left their skins behind them. He would have to get to work, therefore, on their bony parts, and doubtless would attack the skulls for choice. By considering head-form and colour, then, we may help to cover a certain amount of the ground, vast as it is. For remember that anthropology in this department draws no line between ancient and modern, or between savage and civilized, but tries to tackle every sort of man that comes within its reach.
Head-shape is really a far more complicated thing to arrive at for purposes of comparison than one might suppose. Since no part ofthe skull maintains a stable position in regard to the rest, there can be no fixed standard of measurement, but at most a judgment of likeness or unlikeness founded on an averaging of the total proportions. Thus it comes about that, in the last resort, the impression of a good expert is worth in these matters a great deal more than rows of figures. Moreover, rows of figures in their turn take a lot of understanding. Besides, they are not always easy to get. This is especially the case if you are measuring a live subject. Perhaps he is armed with a club, and may take amiss the use of an instrument that has to be poked into his ears, or what not. So, for one reason or another, we have often to put up with that very unsatisfactory single-figure description of the head-form which is known as the cranial index. You take the greatest length and greatest breadth of the skull, and write down the result obtained by dividing the former into the latter when multiplied by 100. Medium-headed people have an index of anything between 75 and 80. Below that figure men rank as long-headed, above it as round-headed. This test, however, as I have hinted, will not by itself carry us far. On the other hand, I believe that a good judge of head-form in all its aspects taken together will generally be able to make a pretty shrewdguess as to the people amongst whom the owner of a given skull is to be placed.
Unfortunately, to say people is not to say race. It may be that a given people tend to have a characteristic head-form, not so much because they are of common breed, as because they are subjected after birth, or at any rate, after conception, to one and the same environment. Thus some careful observations made recently by Professor Boas on American immigrants from various parts of Europe seem to show that the new environment does in some unexplained way modify the head-form to a remarkable extent. For example, amongst the East European Jews the head of the European-born is shorter and wider than that of the American-born, the difference being even more marked in the second generation of the American-born. At the same time, other European nationalities exhibit changes of other kinds, all these changes, however, being in the direction of a convergence towards one and the same American type. How are we to explain these facts, supposing them to be corroborated by more extensive studies? It would seem that we must at any rate allow for a considerable plasticity in the head-form, whereby it is capable of undergoing decisive alteration under the influences of environment; not, of course, at any moment during life, butduring those early days when the growth of the head is especially rapid. The further question whether such an acquired character can be transmitted we need not raise again. Before passing on, however, let this one word to the wise be uttered. If the skull can be so affected, then what about the brain inside it? If the hereditarily long-headed can change under suitable conditions, then what about the hereditarily short-witted?
It remains to say a word about the types of pre-historic men as judged by their bony remains and especially by their skulls. Naturally the subject bristles with uncertainties.
By itself stands the so-called Pithecanthropus (Ape-man) of Java, a regular "missing link." The top of the skull, several teeth, and a thigh-bone, found at a certain distance from each other, are all that we have of it or him. Dr. Dubois, their discoverer, has made out a fairly strong case for supposing that the geological stratum in which the remains occurred is Pliocene—that is to say, belongs to the Tertiary epoch, to which man has not yet been traced back with any strong probability. It must remain, however, highly doubtful whether this is a proto-human being, or merely an ape of a type related to the gibbon. The intermediate character is shown especially in the head form. If an ape, Pithecanthropushad an enormous brain; if a man, he must have verged on what we should consider idiocy.
Also standing somewhat by itself is the Heidelberg man. All that we have of him is a well-preserved lower jaw with its teeth. It was found more than eighty feet below the surface of the soil, in company with animal remains that make it possible to fix its position in the scale of pre-historic periods with some accuracy. Judged by this test, it is as old as the oldest of the unmistakable drift implements, the so-called Chellean (from Chelles in the department of Seine-et-Marne in France). The jaw by itself would suggest a gorilla, being both chinless and immensely powerful. The teeth, however, are human beyond question, and can be matched, or perhaps even in respect to certain marks of primitiveness out-matched, amongst ancient skulls of the Neanderthal order, if not also amongst modern ones from Australia.
We may next consider the Neanderthal group of skulls, so named after the first of that type found in 1856 in the Neanderthal valley close to Düsseldorf in the Rhine basin. A narrow head, with low and retreating forehead, and a thick projecting brow-ridge, yet with at least twice the brain capacity of any gorilla, set the learned world disputing whether thiswas an ape, a normal man, or an idiot. It was unfortunate that there were no proofs to hand of the age of these relics. After a while, however, similar specimens began to come in. Thus in 1866 the jaw of a woman, displaying a tendency to chinlessness combined with great strength, was found in the Cave of La Naulette in Belgium, associated with more or less dateable remains of the mammoth, woolly rhinoceros and reindeer. A few years earlier, though its importance was not appreciated at the moment, there had been discovered, near Forbes' quarry at Gibraltar, the famous Gibraltar skull, now to be seen in the Museum of the Royal College of Surgeons in London. Any visitor will notice at the first glance that this is no man of to-day. There are the narrow head, low crown, and prominent brow-ridge as before, supplemented by the most extraordinary eye-holes that were ever seen, vast circles widely separated from each other. And other peculiar features will reveal themselves on a close inspection; for instance, the horseshoe form in which, ape-fashion, the teeth are arranged, and the muzzle-like shape of the face due to the absence of the depressions that in our own case run down on each side from just outside the nostrils towards the corners of the mouth.
And now at the present time we have twentyor more individuals of this Neanderthal type to compare. The latest discoveries are perhaps the most interesting, because in two and perhaps other cases the man has been properly buried. Thus at La Chapelle-aux-Saints, in the French department of Corrèze, a skeleton, which in its head-form closely recalls the Gibraltar example, was found in a pit dug in the floor of a low grotto. It lay on its back, head to the west, with one arm bent towards the head, the other outstretched, and the legs drawn up. Some bison bones lay in the grave as if a food-offering had been made. Hard by were flint implements of a well-marked Mousterian type. In the shelter of Le Moustier itself a similar burial was discovered. The body lay on its right side, with the right arm bent so as to support the head upon a carefully arranged pillow of flints; whilst the left arm was stretched out, so that the hand might be near a magnificent oval stone-weapon chipped on both faces, evidently laid there by design. So much for these men of the Neanderthal type, denizens of the mid-palæolithic world at the very latest. Ape-like they doubtless are in their head-form up to a certain point, though almost all their separate features occur here and there amongst modern Australian natives. And yet they were men enough, had brains enough, to believe in alife after death. There is something to think about in that.
Without going outside Europe, we have, however, to reckon with at least two other types of very early head-form.
In one of the caves of Mentone known as La Grotte des Enfants two skeletons from a low stratum were of a primitive type, but unlike the Neanderthal, and have been thought to show affinities to the modern negro. As, however, no other Proto-Negroes are indisputably forthcoming either from Europe or from any other part of the world, there is little at present to be made out about this interesting racial type.
In the layer immediately above the negroid remains, however, as well as in other caves at Mentone, were the bones of individuals of quite another order, one being positively a giant. They are known as the Cro-Magnon race, after a group of them discovered in a rock shelter of that name on the banks of the Vezère. These particular people can be shown to be Aurignacian—that is to say, to have lived just after the Mousterian men of the Neanderthal head-form. If, however, as has been already suggested, the Galley Hill individual, who shows affinities to the Cro-Magnon type, really goes back to the drift-period, then we can believe that from veryearly times there co-existed in Europe at least two varieties; and these so distinct, that some authorities would trace the original divergence between them right back to the times before man and the apes had parted company, linking the Neanderthal race with the gorilla and the Cro-Magnon race with the orang. The Cro-Magnon head-form is refined and highly developed. The forehead is high, and the chin shapely, whilst neither the brow-ridge nor the lower jaw protrudes as in the Neanderthal type. Whether this race survives in modern Europe is, as was said in the last chapter, highly uncertain. In certain respects—for instance, in a certain shortness of face—these people present exceptional features; though some think they can still find men of this type in the Dordogne district. Perhaps the chances are, however, considering how skulls of the neolithic period prove to be anything but uniform, and suggest crossings between different stocks, that we may claim kinship to some extent with the more good-looking of the two main types of palæolithic man—always supposing that head-form can be taken as a guide. But can it? The Pygmies of the Congo region have medium heads; the Bushmen of South Africa, usually regarded as akin in race, have long heads. The American Indians, generally supposed tobe all, or nearly all, of one racial type, show considerable differences of head-form; and so on. It need not be repeated that any race-mark is liable to deceive.
