Prehistoric Types of the Human Race.—The earliest record of human life yet discovered is the Pithecanthropus Erectus (Trinil), the apelike man who walked upright, found in Java by Du Bois, about the year 1892. Enough of the skeletal remains of human beings were found at this time to indicate a man of rather crude form and low brain capacity (about 885 c.c.), with possible powers of speech but with no probably developed language or no assumption of the acquaintance with the arts of life.[[4]]

The remains of this man associated with the remains of one other skeleton, probably a woman, and with the bones of extinct animals, were found in a geological stratum which indicates his age at about 500,000 years. Professor McGregor, after a careful anatomical study, has reproduced the head and bust of Pithecanthropus, which helps us to visualize this primitive species as of rather low cultural type. The low forehead, massive jaw, and receding chin give us a vision of an undeveloped species of the human race, in some respects not much above the anthropoid apes, yet in other characters distinctly human.

There follows a long interval of human development which is only conjectural until the discovery of the bones of the Heidelberg man, found at the south of the River Neckar. These are the first records of the human race found in southern Europe. The type of man is still apelike in some respects, but far in advance of the Pithecanthropus in structure and general appearance. The restoration by the Belgian artist Mascré under the direction of Professor A. Rotot, of Brussels, is indicative of larger brain capacity than the Trinil race. It had a massive jaw, distinctive nose, heavy arched brows, and still the receding chin. Not many cultural remains were found in strata of the second interglacial period along with the remains of extinct animals, such as the ancient elephant, Etruscan rhinoceros, primitive bison, primitive ox, Auvergne bear, and lion. A fauna and a flora as well as a geological structure were found which would indicate that this race existed at this place about 375,000 years ago. From these evidences very little may be determined of the Heidelberg man's cultural development, but much may be inferred. Undoubtedly, like the Pithecanthropus, he was a man without the tools of civilization, or at least had not developed far in this way.

About 150,000 years ago there appeared in Europe races of mankind that left more relics of their civilization.[[6]] These were the Neanderthaloid races. There is no evidence of the connection of these races with the Java man or the Heidelberg man. Here, as elsewhere in the evolution of races and species, nature does not work in a straight line of descent, but by differentiation and variation.

In 1856 the first discovery of a specimen of the Neanderthal man was found at the entrance of a small ravine on the right bank of the River Dussel, in Rhenish Prussia. This was the first discovery of the Paleolithic man to cause serious reflection on the possibility of a prehistoric race in Europe. Its age is estimated at 50,000 years. This was followed by other discoveries of the Mid-Pleistocene period, until there were a number of discoveries of similar specimens of the Neanderthal race, varying in some respects from each other. The first had a brain capacity of 1230 c.c., while that of the average European is about 1500 c.c. Some of the specimens showed a skull capacity larger than the first specimen, but the average is lower than that of any living race, unless it be that of the Australians.

Later were discovered human remains of a somewhat higher type, known as the Aurignacian, of the Crô-Magnon race. These are probably ancestors of the living races of Europe existing 25,000 to 50,000 years ago. They represent the first races to which may be accorded definite relationship with the recent races.

Thus we have evidences of the great antiquity of man and a series of remains showing continual advancement over a period of nearly 500,000 years—the Pithecanthropus, Heidelberg, Piltdown, and Neanderthal, though expressing gradations of development in the order named, appear to be unrelated in their origin and descent, and are classed as separate species long since extinct. The Crô-Magnon people seem more directly related to modern man. Perhaps in the Neolithic Age they may have been the forebears of present races, either through direct or indirect lines.

The Unity of the Human Race.—Though there are evidences, as shown above, that there were many branches of the human race, or species, some of which became extinct without leaving any records of the passing on of their cultures to others, there is a pretty generally concerted opinion that all branches of the human race are related and have sprung from the same ancestors. There have been differences of opinion regarding this view, some holding that there are several centres of development in which the precursor of man assumed a human form (polygenesis), and others holding that according to the law of differentiation and zoological development there must have been at some time one origin of the species (monogenesis). So far as the scientific investigation of mankind is concerned, it is rather immaterial which theory is accepted. We know that multitudes of tribes and races differ in minor parts of structure, differ in mental capacity, and hence in qualities of civilization, and yet in general form, brain structure, and mental processes, it is the same human being wherever found. So we may assume that there is a unity of the race.

If we consider the human race to have sprung from a single pair, or even the development of man from a single species, it must have taken a long time to have developed the great marks of racial differences that now exist. The question of unity or plurality of race origins has been much discussed, and is still somewhat in controversy, although the predominance of evidence is much in favor of the descent of man from a single species and from a single place. The elder Agassiz held that there were several separate species of the race, which accounts for the wide divergence of characteristics and conditions. But it is generally admitted from a zoological standpoint that man originated from a single species, although it does not necessarily follow that he came from a single pair. It is the diversity or the unity of the race from a single pair which gives rise to the greatest controversy.
