Note 3 — Introductory material

The influence of environment and heredity on human evolution in general and on the history of the East in particular, though of great importance, cannot be treated in a summary such as this. The influence of climatic and other environmental factors has been ably treated by Prof. Ellsworth Huntington in his various works, such as The Pulse of Asia (Boston, 1907); Civilization and Climate (Yale Univ. Press, 1915), and World-Power and Evolution (Yale Univ. Press, 1919). See also Chap. III. in Arminius Vambéry—Der Islam im neunzehnten Jahrhundert. Eine culturgeschichtliche Studie (Leipzig, 1875). For a summary of racial influences in Eastern history, see Madison Grant—The Passing of the Great Race (N.Y., 1916).
