"The opinion of modern Zoölogists, whose study of the species and breeds of animals makes them the best judges, is against this view of the several origins of man, for two principal reasons. First, That all tribes of men, from the blackest to the whitest, the most savage to the most cultured, have such general likeness in the structure of their bodies and the working of their minds, as is easiest and best accounted for by their being descended from a common ancestry, however distant. Second, That all the human races, notwithstanding their form and color, appear capable of freely intermarrying, and forming crossed races of every combination, such as the millions of mulattoes and mestizoes sprung in the New World from the mixture of Europeans, Africans, and native Americans; this again points to a common ancestry of all the races of man. We may accept the theory of the unity of mankind as best agreeing with ordinary experience and scientific research." (Tylor's _Anthropology_, etc., pp. 5, 6.) EVIDENCE OF LANGUAGE.--Languages, through marked affinities, are grouped together into several great families, i. The _Aryan_, or Indo-European, of which the oldest known branch is the Sanskrit, the language in which the ancient books of the Hindus, the Vedas, were written. With the Sanskrit belong the Iranian or Persian, the Greek, the Latin or Italic, the Celtic, the Germanic or Teutonic (under which are included the Scandinavian tongues), the Slavonian or Slavo-Lettic. 2. The _Semitic_, embracing the communities described in Genesis as the descendants of Shem. Under this head are embraced, first, the Assyrian and Babylonian; secondly, the Hebrew and Phoenician, with the Syrian or Aramaic; and thirdly, the Arabic. The Phoenician was spread among numerous colonies, of which Carthage was the chief. The Arabic followed the course of Mohammedan conquest. It is the language of the northern border of Africa, and has strongly affected various other languages,--the Persian, Turkish, etc. 3. The _Turanian or Scythian_. This is an extensive family of languages. The Finno-Hungarian, which includes two cultivated peoples, the Fins and Hungarians; the Samoyed, stretching from the North Sea far eastward to the boundary between Russia and China; and the Turkish or Tartar, spreading from European Turkey over a great part of Central Asia, are connected together by family ties. They spring from one parent stock. Whether the Mongolian and the Tungusic--the last is the language of the Manchus--are also thus affiliated, is a point not absolutely settled.
