ABSTRACT
Geography is concerned primarily with distributions, and of these distributions none is more important than the distribution of man himself. Anthropology is of course a discipline quite distinct in many ways from geography, but there is a common ground in the pattern displayed by the distribution of the main divisions of man over the face of the earth. We geographers must learn from the anthropologists what are the characteristics of the various types of man, but in return we can plot these characteristics, and by using a technique which the writer has ventured to call ‘Evolution from the map’ we can make valuable deductions as to the evolution and classification of man, which would not be in the least apparent to a student who did not chart his data. Furthermore, our knowledge of the immemorial corridors used by primitive man is much more complete now than it was a few decades ago, and this also gives us the key to the meaning of various race-distributions as exhibited on the map.
