Note 41 — LECTURE III. THE BEGINNINGS AND SUBDIVISIONS OF RACES.
Reading edition
On the recent connection of North Africa with Europe, see A. R. Wallace, The Geographical Distribution of Animals, Vol. I., pp. 38, 39; De Mortillet, Le Prehistorique Antiquité de l’Homme, p. 225. “Even in post-tertiary times,” writes Huxley (Physiography, p. 308), “Africa was united to Europe at the Straits of Gibraltar and across by Malta and Sicily. The Sahara is an old sea bottom, which was below water at a comparatively recent period.” “The Atlas mountains,” remarks Suess, “belong to the intricate orographic system of Europe.” (Das Antlitz der Erde, Bd. I., s. 462.)
