We need hardly say that animals, like plants, are attached to various localities which they rarely quit with impunity, since they have not the faculty of acclimatizing themselves at will. The elephant lives only in India and in certain parts of Africa; the hippopotamus and giraffe in other countries of the same continent; monkeys exist in very few portions of the globe, and if we consider their different species, we shall find that the place of abode of each species is very limited. For instance, of the larger apes the orang-outang is found only in Borneo and Sumatra, and the gorilla in a small corner of Western Africa. Had man originated in all those places where now his different races are found, he would stand alone as an exception among organized beings. Reasoning then by induction, that is, applying to man all that we observe to obtain generally among beings living on the surface of the globe, we come to the conclusion that the human species, in common with every vegetable or animal species, had but one centre of creation. Around the central tableland of Asia are found the three organic and fundamental types of man, that is to say, the white, the yellow, and the black. The black type has been somewhat scattered, although it is still found in the south of Japan, in the Malay Peninsula, in the Andaman Isles, and in the Philippines, at Formosa. The yellow type forms a large portion of the actual population of Asia, and it is well known whence came those white hordes that invaded Europe at times prehistoric and in more recent ages; those conquerors belonged to the Aryan or Persian race, and they came from Central Asia. Around the central tableland of Asia, we find not only the three fundamental types of the human species, but the three types of human speech. Does not this, therefore, afford ground for presumption, if not actual proof, that man first appeared in this very region which Scripture assigns as the birthplace of the human race? It is from this central tableland of Asia, radiating so to say around this point of origin, that man has progressively occupied every part of the earth. Migration commenced at a very early period; the facility with which our species becomes habituated to every climate and accommodates itself to variations of temperature, taken in connection with the nomadic character which distinguished primitive populations, explains to us the displacement of the earlier inhabitants of the earth. Soon, means of navigation, although rude, were added to the power of traveling by land, and man passed from the continent to distant islands, and thus peopled the archipelagoes as well as the mainland. By means of transport, effected in canoes formed from the trunks of trees barely hollowed out, the archipelagoes of the Indian Ocean, and finally Australia, were gradually peopled.
