Philologists speak with less unanimity of a third group of languages, the HAMITIC, which some declare to be distinct from, and others allied to, the Semitic. The weight of opinion inclines now towards the idea of some primordial connection of these two groups. The Hamitic group is certainly a much wider and more various language group than the Semitic or the Aryan, and the Semitic tongues are more of a family, have more of a common likeness, than the Aryan. The Semitic languages may have arisen as some specialized proto-Hamitic group, just as the birds arose from a special group of reptiles (Chap. IV). It is a tempting speculation, but one for which there is really no basis of justifying fact, to suppose that the rude primordial ancestor group of the Aryan tongues branched off from the proto-Hamitic speech forms at some still earlier date than the separation and specialization of Semitic. The Hamitic speakers to-day, like the Semitic speakers, are mainly of the Mediterranean Caucasian race. Among the Hamitic languages are the ancient Egyptian and Coptic, the Berber languages (of the mountain people of north Africa, the Masked Tuaregs, and other such peoples), and what are called the Ethiopic group of African languages in eastern Africa, including the speech of the Gallas and the Somalis. The general grouping of these various tongues suggests that they originated over some great area to the west, as the primitive Semitic 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. [Illustration: Possible Development of LANGUAGES disregarding admixtures, e.g. Turkish elements in Russian, Latin in English, Hamitic in Keltic, & so forth; & omitting various Indian, Melanesian & other groups.] 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.
