INTRODUCTION.
ETHNIC GROUPS AND ZOOLOGICAL SPECIES.
Difficulties in applying to Man the terms of zoological nomenclature—Criterion of species—Terms to give to the “Somatological Units” constituting the genus Homo—Monogenesis and Polygenesis—The “Ethnic Groups” are constituted by the different combinations of the “Somatological Units” or “Races”—Somatic characters and ethnic characters.
THE innumerable groups of mankind, massed together or scattered, according to the varying nature of the earth’s surface, are far from presenting a homogeneous picture. Every country has its own variety of physical type, language, manners, and customs. Thus, in order to exhibit a systematic view of all the peoples of the earth, it is necessary to observe a certain order in the study of these varieties, and to define carefully what is meant by such and such a descriptive term, having reference either to the physical type or to the social life of men. This we shall do in the subsequent chapters as we proceed to develop this slight sketch of the chief general facts of the physical and psychical life of man, and of the most striking social phenomena of the groups of mankind.
But there are some general terms which are of more importance than others, and their meaning should be clearly understood from the first. I refer to expressions like “people,” “nation,” “tribe,” “race,” “species,” in short, all the designations of the different groupings, real or theoretic, of human beings. Having defined them, we shall by so doing define the object of our studies.
Since ethnography and anthropology began to exist as sciences, an attempt has been made to determine and establish the great groups amongst which humanity might be divided. A considerable diversity of opinion, however, exists among leading scientific men not only as to the number of these groups, of these “primordial divisions” of the human race, but, above all, as to the very nature of these groups. Their significance, most frequently, is very vaguely indicated.
In zoology, when we proceed to classify, we have to do with beings which, in spite of slight individual differences, are easily grouped around a certain number of types, with well-defined characters, called “species.” An animal can always be found which will represent the “type” of its species. In all the great zoological collections there exist these “species-types,” to which individuals may be compared in order to decide if they belong to the supposed species. We have then in zoology a real substratum for the determination of species, those primordial units which are grouped afterwards in genera, families, orders, etc.
Is it the same for man? Whilst knowing that the zoological genus Homo really exists quite distinct from the other genera of the animal kingdom, there still arises the question as to where the substratum is on which we must begin operations in order to determine the “species” of which this genus is composed. The only definite facts before us are these groups of mankind, dispersed over the whole habitable surface of the globe, to which are commonly given the names of peoples, nations, clans, tribes, etc. We have presented to us Arabs, Swiss, Australians, Bushmen, English, Siouan Indians, Negroes, etc., without knowing if each of these groups is on an equal footing from the point of view of classification.
Do these real and palpable groupings represent unions of individuals which, in spite of some slight dissimilarities, are capable of forming what zoologists call “species,” “sub-species,” “varieties,” in the case of wild animals, or “races” in the case of domestic animals? One need not be a professional anthropologist to reply negatively to this question. They are ethnic groups formed by virtue of community of language, religion, social institutions, etc., which have the power of uniting human beings of one or several species, races, or varieties,[1] and are by no means zoological species; they may include human beings of one or of many species, races, or varieties.
