MAN has been described as a “walking museum of paleontology.” He is like a mountain whose foundations were laid in a time so ancient that even the paleontologist hardly finds a record to decipher; whose strata testify to the progress of life through all the succeeding ages; whose surface, deeply ploughed by the glaciers, is clothed with grass and forest, flower and fruit, the harvest of the life of to-day.

Some of his organs are exceedingly old, while others are but of yesterday; yet all are highly developed in due proportion, knit and harmonized in a marvellously tough, vigorous, adaptable body, the instrument of a thinking and willing mind. Most surviving animals have outlived their day of progress; they have “exhausted their lead,” to borrow a miner’s expression, and have settled down in equilibrium with their surroundings. But discontented man is wisely convinced that his golden age lies in the future, and that his best possessions are his hopes and dreams, his castles in Spain. He is chiefly a bundle of vast possibilities, of great expectations, compared with which his achievements and realizations are scarcely larger than the central point of a circle compared with its area.

Physically he belongs to the great branch or phylum of vertebrate animals having a backbone—sometimes only a rod of cartilage—an internal locomotive skeleton, giving the possibility of great strength and swiftness, and of large size. Large size, with its greater heat-producing mass relative to its radiating surface, implies the possibility of warm blood, or constant high temperature, resulting in greater activity of all the organs, especially of the glands and the nervous system. Large size, as a rule, is accompanied by long life—giving opportunities for continuous and wide experience, and hence for intelligence. Yet most vertebrates have remained cold-blooded, and only a “saving remnant” even of men is really intelligent. Man belongs to the highest class of vertebrates, the Mammals, which produce living young and suckle them. Among the highest mammals, the Primates, or apes, the length of the periods of gestation, of suckling the young, and of childhood, with its dependence upon the mother, have become so long that she absolutely requires some sort of help and protection from the male parent. From this necessity have sprung various grades and forms of what we may venture to call family life, with all its advantages. How many mammals have attained genuine family life and how many men have realized its possibilities?1

The upward march of our ancestors was neither easy nor rapid. They were anything but precocious. They were always ready to balk at progress, stiff-necked creatures who had to be driven and sternly held in the line of progress by stronger competitors. The ancestors of vertebrates maintained the swimming habit, which resulted in the development of the internal skeleton and finally of a backbone, not because it was easiest or most desirable, but because any who went to the rich feeding-grounds of the sea-bottom were eaten up by the mollusks and crabs. Our earliest air-breathing ancestors were crowded toward, and finally to the land, and into air-breathing by the pressure of stronger marine forms like sharks, or by climatic changes.2 Reptiles, not mammals, dominated the earth throughout the Mesozoic era, and harried our ancestors into agility and wariness; at a later period the apes remained in the school of arboreal life mainly because the ground was forbidden and policed by the Carnivora. They and their forebears were compelled to forego some present ease and comfort, but always kept open the door to the future.

In spite of all this vigorous policing, malingerers and deserters turned aside from the upward line of march at every unguarded point or fork in the road, escaped from the struggle, and settled down in ease and stagnation or degeneration, like our very distant cousins, the monkeys and lower apes. Long-continued progress is a marked exception, not the rule, in the animal world, and is maintained only by the “saving remnant.” And these continue to progress mainly because Nature is “always a-chivying of them and a-telling them to move on,” as Poor Joe said of Detective Bucket, and her guiding wand is the spur of necessity.

The Primates, or apes, are, as we have seen, the highest order of the great class of mammals. Most of them, like other comparatively defenseless vertebrates, are gregarious or even social.3 They have a feeling of kind, if not of kindness, toward one another. This sociability, together with the family as a unit of social structure, has contributed incalculably to human intellectual and moral development. Man is a Primate, a distant cousin of the highest apes, though no one of these represents our “furry arboreal ancestor with pointed ears.” Arboreal life was an excellent preparatory training toward human development. Our primate ancestor was probably of fair size. In climbing he set his feet on one branch and grasped with his hands the branch above his head. Foot and leg were used to support the body, hand and arm for pulling. Thus the hand became a true hand and the foot a genuine foot, opening up the possibility of the erect posture on the ground and the adaptation of the hand to higher uses. Meanwhile the climbing and leaping from branch to branch, the measuring with the eye of distances and strength of branches, the power of grasping the right point at the right instant, and all the complicated series of movements combined in this form of locomotion furnished a marvellous set of exercises not only for the muscles but for the higher centres in the cortex of the brain. Very probably gregarious life and rude play, so common among apes, was an extension course along somewhat similar lines.

Our ancestors became at home in and well adapted to arboreal life, but the adaptation was never extreme. It was rather what Jones4 has called a “successful minimal adaptation.” They used arboreal life without abusing it by over-adaptation, which would have enslaved them, and made life on the ground an impossibility when the time came for their promotion to this new and more advanced stage.

At the close of his arboreal life the ape had inherited or acquired the following assets: His vertebrate and mammalian structure had given him a large, vigorous, compact, athletic, adaptable body. The mammalian care of the young had insured their survival, but only at the expense of great strain and risk of the mother. Something at least approaching family life was already attained. Arboreal life with its gymnastic training had moulded the body, differentiated hand and foot, given the possibility of erect posture, emancipating the hand from the work of locomotion and setting it free to become a tool-fashioning and tool-using organ. The ape has keen sense-organs, an eye for distances, and other conditions; and the use of these powers has given him a brain far superior to that of any of his humbler fellows. These are full of great possibilities and opportunities, if he will only use them.

But why did our ancestor descend from his place of safety in the trees and live on the ground, exposed to the attacks of fierce, swift, and well-armed enemies? Very few of the Primates, except the rock and cliff-inhabiting baboons, ever made this great venture. There must have been some quite compelling argument to induce him to take so great a risk. The change took place probably at some time during the latter half of the Cenozoic or Tertiary period, the last great division of geological time, the Age of mammals.5 The earliest Tertiary Epoch, the Eocene, was a time of warm and equable climate, when apes lived far north in Europe, and doubtless in Asia also. Some of these apes were of fair or large size, showing that conditions were favorable and food abundant. The next epoch, the Oligocene, was similar but somewhat cooler. The third, the Miocene, was cooler still and dryer. Palms now forsook northern Europe, being gradually driven farther and farther south. Life became more difficult, food scarcer. Apes could not longer survive in northern Europe, but had to seek a warmer, more favorable, environment farther south, for many of the fruit and food trees had been crowded out and famine threatened.6 But insects and other small and toothsome animals remained on the ground, and were abundant along the shores of rivers and lakes. There, too, were fruits and berries, roots and tubers. There the food supply was still more than sufficient.

Thus far we have glanced at Europe only. But the same changes are taking place in Asia, the cradle and home of most placental mammals, the main area of a huge zoological province of which Europe was but a westward projection, and with which America had direct connection from time to time in the region of Behring’s Straits. Here, during late Miocene and early Pliocene times, in the latter part of the Cenozoic era, a dryer and somewhat harsher climate had been accompanied by the appearance of wide plains fitted for grazing animals, as well as stretches of forest, with all varieties of landscape favoring great diversity as well as abundance of mammalian life. It was, perhaps, the golden age for most mammals, when food was plenty, climate not too severe, and every prospect pleased. This slow and gradual, but fairly steady, lowering of temperature was to culminate in the Great Ice Age of the Pleistocene Epoch, so destructive to mammalian life in the northern hemisphere.

A second climatic change, perhaps even more important than the lowering temperature, was the increase of aridity. Even during the Oligocene Epoch “the flora indicates a lessening humidity and a clearer differentiation of the seasons,”7 The great trough of the inland sea which had stretched from the Mediterranean to the Indian Ocean began to rise, the first uplift taking place along the Pyrenees and western Alps. The Miocene was marked by a series of great movements. The old inland sea was displaced, subsidence gave place to uplift, and the greatest mountain system of the globe, including the Alps and the Himalayas, began to grow through vast repeated uplifts in the crust.8 The continents were elevated and widened. The forest-dwelling types became restricted and largely exterminated, and animals of the plains, in the form of horses, rhinoceroses, and the cloven-hoofed ruminants, expanded in numbers and in species. This profound faunal change implies dryer climate. There was now a lesser area of tropic seas to give moisture to the atmosphere. The mountains were now effective barriers, shutting off the moisture-bearing winds from the interior of the continents.

These changes would have been noticeable in Europe north of the Alps, but were far more so in central Asia along the northern face of the great plateau of Thibet, with its eastern and western buttresses, and its towering rampart of the Himalayas on the south, cutting off the warm moisture of the Indian Ocean. Northward of this vast plateau and westward over the far less elevated Iranian plateau and Afghanistan, forest was fast being replaced by parklands of mingled groves and glades, or by grassy plains, or even by dry steppes. Dessication, aridity of climate, was fast compelling forest and arboreal mammals to migrate or radically change their habits of life.9

Almost all the apes found their old environment and continued their arboreal life by migrating far southward through India or into Africa. But at the rear of the retreating host were forms from the cooler northern regions. They were hardy and vigorous, and probably larger than most of their fellows. Possibly some of them were caught in isolated decreasing areas of forest surrounded by steppe or plain. Some of them, at least, began to descend from the trees, to seek the new food supplies of riversides, glades, and thickets, and thus gradually to become accustomed to life on the ground. It was a very hazardous experiment; only the most hardy and wary and the quickest in perception, wit, and movement survived. Among these were our ancestors, driven like all their forebears by the spur of necessity into a new mode of life under trying conditions.

They were still only apes, with long arms and short legs, and probably scrambled mostly on all fours. They had heavy brows, retreating foreheads, projecting jaws, and a brutal physiognomy. Of the mental life of the man who was to be descended from them there were few signs. They were bundles of very slight possibilities.

But let us not “despise the day of small things.” They were still far from the invisible line between apedom and manhood. Physically they resembled man quite closely. They had hand and foot, and a fair-sized brain, though they had scarcely begun to realize the possibilities of these structures.

Arboreal life could teach them little more; continuance in that school would have meant a very comfortable stagnation. They were now promoted to a new school of vastly more difficult problems, greater risks and dangers, and more severe and trying discipline. They had had an excellent course of manual and sensory training; now they must continue this and add to it the use of whatever wits they had, under peril of death. Nature was still compelling them to “move on.”

This descent to the ground probably was accomplished either in India or on the Iranian plateau, or somewhat farther to the northeast, somewhere in the great horseshoe of parkland which curved around the western buttress of the great central Asiatic plateau of Thibet. Can we locate it somewhat more definitely?10

At this time, during the Pliocene Epoch, there were being deposited in India the so-called Siwalik strata—vast, ancient flood-plains, stretching for a distance of 1,500 miles along the southern foot-hills of the Himalayas. They are composed of materials washed down from the mountains by a system of rivers, persisting with little change into the present. Says Osborn of the mammals found here: “It is altogether the grandest assemblage of mammals the world has ever seen, distributed through southern and eastern Asia, and probably, if our vision could be extended, ranging westward toward Persia and Arabia into northern Africa. It is the most truly cosmopolitan aggregation because in its Upper Pliocene stage it represents a congress of mammals from four great continents. … The only continents which do not contribute to this assemblage are South America and Australia.”11 The older, Miocene, portions of this fauna are chiefly browsing forest forms, emphasized by the absence of both horses and Hipparion, as well as of grazing types of cattle and antelopes. Grazing forms, showing the decline of the forest and the spread of open parkland and grassy areas, become abundant during the Pliocene Epoch. “Among the Primates we find the Orang, an ape now confined to Borneo and Sumatra; also the Chimpanzee, another ape, now confined to Africa, the Siwalik species displaying a more human type of dentition than that of the existing African form.”

In the older, Miocene, portion we find Sivapithecus, an ape which Pilgrim considers as more nearly resembling man than any other genus of anthropoids, while Gregory speaks of it as belonging to the anthropoid line.12 Somewhat later, in late Pliocene or early Pleistocene, there was living not far away, in Java, a far more renowned form, Pithecanthropus erectus, Du Bois, which seems to stand almost exactly midway between higher apes and man. The remains consisted of two molar teeth, a thigh-bone, and the top of a skull. The cranium is low, the forehead exceedingly retreating, giving but very small space for the frontal lobes of the brain. But the brain-cast, made from the cranial cavity, shows, according to Du Bois, that the speech area is about twice as large as in certain apes, though only one-half as large as in man. In size the brain stands somewhat above midway between the highest recent apes and the lowest existing men. The thigh-bone shows that Pithecanthropus could have stood and walked erect quite comfortably. There has been and still is much difference of opinion regarding the position of this most interesting being. Opinion was long divided nearly equally between those who considered it as the highest ape and others who held it to be the very lowest man.

It is worthy of notice that, when Pithecanthropus was alive, “Java was a part of the Asiatic continent; and similar herds of great mammals roamed freely over the plains from the foot-hills of the Himalaya Mountains to the borders of the ancient Trinil River, while similar apes inhabited the forests. At the same time the Orang may have entered the forests of Borneo, which are at present its home.”13 Where man’s distant cousins, the anthropoid apes, and his still nearer relation, Pithecanthropus, were all living and some, at least, apparently progressing, could hardly have been far from his original home. But the climatic conditions of that time lead us to seek his original cradle somewhat farther northward than India, or even Beluchistan, and nearer to, if not in, the great steppe zone of central Asia. We lose sight of our ape-man as he is advancing toward the threshold of manhood, not far away. Whether we think that Pithecanthropus was approaching or had already passed it depends much upon where we draw the line between ape and man, a line largely artificial and as difficult to fix as the day and hour when the youth becomes of age, and what human characteristics we select to mark it. In his erect posture and some other physical traits he seems already to have attained manhood; mentally he was probably far inferior to even the lowest savage races of to-day. We are not sure whether he was our ancestor or merely a cousin of our ancestor, once or twice removed; we still lack foundations for any hypotheses as to exactly when, where, or how the erect ancestral ape-man emerged into real manhood.

Millennia passed between the days of Pithecanthropus and the first human migrations, and we may imagine primitive man as having become fairly well accustomed to life on the ground, and as having mastered his first lessons in meeting its dangers and difficulties. He had probably taken possession of a much wider area than the home of the ape-man, perhaps of the whole of the parkland zone curving around the western buttresses of the plateau of Thibet. From this region routes of migration radiated in all directions, all the more open because of the elevation of land which lasted through Upper Pliocene and early Pleistocene times.14 Sumatra and Java then formed an extension of the Malay Peninsula, reaching more than 1,000 miles into the Indian Ocean; while the Orang seems to have been able to reach Borneo somewhat earlier. The way was equally clear westward into Europe, the Dardanelles being then replaced by a land bridge, while a second bridge spanned the Mediterranean over Sicily into Italy, and a third existed at Gibraltar.15 These routes were evidently followed by herds of great herbivora, and probably by the earliest human emigrants into Europe.

Following Keane,16 we shall divide mankind into four great groups or races, and then glance at their radiation from southwestern Asia toward all parts of the globe. These great primitive divisions are:

I. Negroids. Color yellowish brown to black, stature large or very small. Hair short, black or reddish brown, frizzly, flattened-elliptical in cross-section. Nose broad and flattened. Cheek-bones small, somewhat retreating. Examples: Negritoes, Negroes.

II. Mongoloids. Color yellowish. Stature below average. Hair coarse, lank, round in cross-section. Nose very small. Cheek-bones prominent. Examples: Malays, Chinese, Japanese, Thibetans, Siberian “Hyperboreans.”

III. Americans. Color reddish or coppery. Stature large. Hair long, lank, coarse, black, round in cross-section. Nose large, bridged, or aquiline. Cheek-bones moderately prominent. (Probably a branch of II.) Examples: Indians of North and South America.

IV. Caucasians. Color pale or florid. Hair long, wavy or straight, elliptical in cross-section. Nose large, straight or arched. Cheek-bones small, unmarked. Examples: Hamitic, Semitic, and European peoples.

We may now imagine quite primitive human beings starting from their early home and seeking their fortunes widely apart. They came under quite different climatic and other physical conditions. Their environment, problems, stimuli, and opportunities were unlike. Thus, having become more or less unlike in the homeland, they gradually became differentiated into the present great groups or races already mentioned. Some started earlier or marched more rapidly than others. Many proved unequal to the dangers and difficulties of the journey or new place of settlement, and disappeared. Many stagnated or degenerated. Only the comparatively successful or fortunate have survived. Hence, our scheme is hardly an adequate expression of prehistoric racial groups and their characteristics, except in very general outline.

We have seen that the apes, retreating before the approach of harsh and dry climatic conditions and diminished forest areas and food supply, migrated southward into India and Africa. The Orang settled in Borneo, Pithecanthropus in Java, the Chimpanzee and Gorilla went into Africa. These routes presented the fewest difficulties and demanded the least readaptation or change of habit. The climate was mild and food generally abundant and easily obtained. Their environment was neither stimulating, trying, nor exacting. Progress was hardly to be expected, but survival was far easier than in more northerly regions.

The Negritos followed almost exactly the same routes. We find them purest and perhaps least modified in the “Pygmies” of the African forests; but also in the Malay Peninsula, the Andaman Islands, and the Philippines. De Morgan believes that he has found proofs of their presence on the Iranian plateau at a comparatively late date.

Behind them Negroid peoples poured into Africa, apparently in successive waves. Some of them went into the Malay Peninsula, probably generally submerging the Negritos, and reached New Guinea and Australia. Inhabiting a series of islands and other more or less isolated areas, mingling often with Negritos, probably later also more or less with the Malays, they became much modified, and their relations to the African Negroes and to one another are still anything but clear.

The Mongoloids pushed eastward. The earliest migrations seem to be those of the Malays, a great, very interesting, and little-known though much-studied group of peoples. They followed the oceanic Negritos along the Malay Peninsula and occupied the great chains of islands stretching through the Indian Ocean and far into the Pacific, through more than ninety degrees of longitude along the equator. But much of this spread is probably of quite recent date.

The Mongoloid peoples seem to have passed along the northern front of the Central Asiatic plateau into Siberia, China, and Japan, and to have sent off the great American branch. Even before the Mongols had started on their eastward journey the Caucasians may have turned westward, following the old Negroid route. There was probably also more or less of an eastern dispersal, but we cannot consider the problem of these Oriental Caucasic remnants and traces. The great body went westward. The Hamitic peoples distributed themselves along the southern shore of the Mediterranean, and many may well have occupied a large part of the Sahara region, then a land of watercourses capable of supporting a large population. Behind them came the Semitic folk. Judging from their languages the Hamitic and Semitic peoples seem to have been in contact over a wide area, and for a long space of time. The Semites found a new and permanent home in Arabia, on whose plateaus and surrounding grasslands they increased and multiplied, and sent off fresh waves of migration and conquest in all directions.

We have already noticed that our classification of races is based upon a study of recent and still surviving peoples. The very earliest inhabitants of Europe would find no place in it. Probably they long antedated the Hamites. African Negroids and Caucasians came from a common home, and journeyed for a time over a common road, though probably at far different times. It would be strange if the earliest inhabitants of Europe showed no traces of this common home and ancestry. Since the remote period which we are considering Negroes and Caucasians have become widely different, and their racial characters have become clear and sharp. This may not have been altogether the case with the first peoples to arrive in Europe. But attempts to relate the Neanderthal crania with those of modern Australians or Tasmanians, or any existing race, have met with no great success. In regard to these questions we are still in the dark.

Beside the African routes into Europe, along the south shore of the Mediterranean and over the Sicilian and Gibraltar land bridges, while they lasted, two others must be noticed. One of these extended through Asia Minor and across the land bridge at the Dardanelles, while the second led westward along the northern border of the Caspian and Black Seas and the Caucasus Mountains. The most southerly of these four routes through Africa were probably the first to be travelled, the most northerly last of all. We shall have to study these routes more closely in a later chapter.

It was at some time during the Glacial period, the Great Ice Age, when a vast ice-cap covered northern Europe with glaciers extending far southward and advancing or retreating according to climatic conditions, that man arrived in Europe. During the first Glacial Epoch the advance of the ice covered the most northern part of Great Britain and the Rhine valley almost as far south as Cologne; Scandinavia was completely buried, like central Greenland to-day, and North Germany probably to the Harz Mountains. Eastward the southern edge of the ice sheet ran nearly along the line of 50° N. lat. across Russia. In Siberia the effects were less marked and the limits were much farther northward. Between the parallel of 50° and the northern edge of the Alpine glaciers a zone was left ice-free, but three-fifths of Germany was overwhelmed. Southern England and France, not yet separated by the English Channel, formed one great habitable province, and but a small part of France was glaciated. The climate was tempered by proximity to the sea.17 The average yearly temperature of northern Europe was probably not more than 4°-6° Cent. (39°-43° Fahr.), which is colder than at present. But the formation of these enormous masses of ice demanded heavy snowfall and a moist or very damp climate. Hence the edge of the great ice sheet advanced or retreated according to climatic conditions.

There were four periods of advance before the final retreat of the ice, not counting minor oscillations.18 These are known as the Gunz, Mindel, Riss, and Wurm Glacial Epochs. Alternating with these were the interglacial epochs of ice retreat—the Gunz-Mindel, Mindel-Riss, and Riss-Wurm; while the final retreat is usually termed post-glacial. During the first and second interglacial epochs the climate appears to have been warmer than at present. But at times dryness may have contributed to the retreat of the ice even more than warmth, and then the climate would have been continental, harsh, and extreme.

Even during epochs of glacial advance conditions in France and in the German zone must have been better than we should expect. Some kind of grazing or browsing pasturage must have been rich and abundant to support large animals like the reindeer or even the woolly mammoths characteristic of the second and third glacial epochs, which furnished abundant food for prehistoric hunters. Farther south the glacial epochs may well have been times of heavy rainfall, transforming the Sahara desert and the dryer steppes and plateaus of Asia into veritable gardens.

The retreating ice left behind it a land covered with rocks, clays, gravels, and sands brought by the glaciers and their streams. Here and there basins had been gouged out where lakes or ponds long remained—as in Maine and Minnesota to-day—to be later drained, or, if shallow, to be overgrown with sphagnum and changed into great bogs. Scattered thickets of shrubs and stunted hardy trees, poplars, willows, and others occurred. In sheltered and well-drained valleys and mountainsides the trees grew larger and even forests began to appear. This tundra landscape still characterizes wide areas of northern Canada and Siberia.19

The tundra was followed by steppe conditions, where elevation of land to the north and northwest had cut off the tempering oceanic winds. The climate was harsh, dry, continental, with cold winters and hot summers. The winds carried great storms of dust and piled it up in drifts in valleys and on suitably situated mountainsides in the form of loess, so important to the future agricultural development of Europe, though its most massive accumulation is seen in China, which received and held the driftings from the great elevated plains of central Asia. As the climate became moister, if the temperature did not fall too low, steppe finally gave way to the meadow and forest of modern Europe. Tundra, steppe, and forest had each its special types of animal as well as plant life. The characteristic tundra animal is the reindeer, though musk-ox, woolly mammoth, and others were wide-spread at this time. The peculiar steppe animal is the horse. The characteristic forest and meadow animals are the deer and their allies; the wolf and bear; the wild boar and cattle seem to be at home in forest and glade and along the streams.

In France, where there was far less glaciation, the succession of tundra, steppe, and forest is less apparent. Here we find a mingling of varied forms which have come in from very different regions, driven from their original homes by change of climate or drawn by favorable conditions.

The first unmistakable relic of man in Europe is a human lower jaw found in the Mauer sands near Heidelberg, some seventy-nine feet below the surface of the bluff.20 It seems to belong to the second or Mindel-Riss interglacial epoch, and its age is estimated by Osborn at about 250,000 years. Remains characteristic of the oldest Paleolithic epochs occur between thirty and forty-five feet below the surface. If we are to find an archæological name for this epoch, there seems to be no better one than Eolithic, the dawn of the Stone Age, when European man had hardly more than begun to chip a stone implement, although we must recognize the unreadiness of many or most archæologists to find a place for such rude products.21

The third interglacial period (Riss-Wurm) and the fourth period of advance (Wurm) cover what is known as Lower Paleolithic time, which is the earlier four-fifths or more of the Old Stone Age or Paleolithic period, extending approximately from 125,000 BC, to 25,000 BC During the greater part of this period Europe was occupied by the Neanderthaloid people. Neanderthal man had a very large head with heavy, overhanging eyebrows meeting above the nose, and a markedly retreating forehead. The face was high and the large nasal opening indicates a broad, flat nose. The lower jaw was heavy and the chin retreating. The trunk was short, thick, and robust, the shoulders broad; the limbs short and heavy, the arms and lower legs relatively short, and the hands very large. Although the much-discussed Piltdown skull may quite probably be regarded as belonging to the earliest part of this period, the finer form of cranium seems to testify to a higher race of better mental development than the Neanderthaloids, huddling in their caves and shelters. It may easily represent a far more progressive ancestral race, of which they are somewhat degenerate descendants, though Osborn dissents from this view.22

Their remains are found in caves and rock-shelters all over Europe. Here we find their hearths; the bones of the animals which they had hunted for their food; their almond-shaped flint axes, “hand-stones” (Coups-de-Poing), the scrapers for dressing skins and shaving wooden tools, and a variety of other forms. Here they buried their dead. During the third warm interglacial epoch they lived in the open, as at the station of Chelles, which has given its name to the earliest Paleolithic epoch.23 Their origin and route of migration is quite uncertain, but it seems probable that they entered Europe from the southern shore of the Mediterranean.

The post-glacial period is characterized by the final retreat of the ice. The change of climate was not steady but marked by a series of oscillations, repeating on a much smaller scale the glacial and interglacial epochs of the long past. The climatic change is accompanied by the appearance of tundra and steppe, followed by meadows and the forest conditions of modern times. Game was abundant and general conditions severe but healthy and fairly favorable.

A new race has appeared on the scene which replaced the Neanderthal folk, and had practically none of their primitive or degenerate, ape-like characteristics.24 The Cro-Magnon people have excited the wonder and admiration of all anthropologists. They were of tall stature, had long legs, especially below the knee, giving swiftness in running. The forehead is broad and of good height, the features are rugged but attractive, and the brain is very large. They seem to represent a new race and new immigration, probably from Asia, which spread over Europe.

The Cro-Magnon brain was anything but dull. In this remote time, more than 20,000 years ago, there sprang up an art never since surpassed in its own field except, perhaps, by that of the Greeks. Their bone implements are adorned with the most lifelike carvings or sculptures. On the walls of caves we find paintings as realistic and alive, and often as finely executed in detail and coloring, as the best animal painters of our day could produce. These people must have had a high and keen appreciation of the beauty of form and proportion. All this artistic movement must have had its source in new ideas and conditions, springing from a thinking as well as a feeling and observing mind. They also frequently buried their dead, decorated with strings of perforated shells, and surrounded by flints or sometimes by a layer of red earth or ore. With them were the bones of food animals and the flint weapons needed for the journey into or use in the life beyond.

The life of the Cro-Magnon hunters on their arrival in Europe was anything but unendurable, especially along the Riviera. There were open-air encampments where men passed at least the summer months in tents or huts. The race seems to have culminated during the cold middle Magdalenian epoch, which indicates that they were well adapted to its conditions. Game was abundant and relatively easily captured. They had food and raiment, fair shelter, excellent art, alert brains, and probably a fair degree of social life. They may well have been content, courageous, and full of hope for themselves and their descendants.
