may have arisen to the east of the Red Sea divide. That divide was probably much more effective in Pleistocene times; the sea extended across to the west of the Isthmus of Suez, and a great part of lower Egypt was under water. Long before the dawn of history, however, Asia and Africa had joined at Suez, and these two language systems were in contact in that region. And if Asia and Africa were separated then at Suez, they may, on the other hand, have been joined by way of Arabia and Abyssinia.
These Hamitic languages may have radiated from a centre on the African coast of the Mediterranean, and they may have extended over the then existing land connections very widely into western Europe.
All these three great groups of languages, it may be noted, the Aryan, Semitic, and Hamitic, have one feature in common which they do not share with any other language, and that is grammatical gender; but whether that has much weight as evidence of a remote common origin of Aryan, Semitic, and Hamitic, is a question for the philologist rather than for the general student. It does not affect the clear evidence of a very long and very ancient prehistoric separation of the speakers of these three diverse groups of tongues.
The bulk of the Semitic and Hamitic-speaking peoples are put by ethnologists with the Aryans among the Caucasian group of races. They are "white." The Semitic and Nordic "races" have a much more distinctive physiognomy; they seem, like their characteristic languages, to be more marked and specialized than the Hamitic-speaking peoples.
§ 5
Across to the north-east of the Aryan and Semitic areas there must once have spread a further distinct language system which is now represented by a group of languages known as the Turanian, or Ural-altaic group. This included the Lappish of Lapland and the Samoyed speech of Siberia, the Finnish language, Magyar, Turkish or Tartar, Manchu and Mongol; it has not as a group been so exhaustively studied by European philologists, and there is insufficient evidence yet whether it does or does not include the Korean and Japanese languages.
