SELF-DOMESTICATION

L. S. B. Leakey, The Progress and Evolution of Man in Africa (London: Oxford University Press, 1961).

      I submit that once man became a maker of tools to a set and regular pattern, he initiated the process of self-domestication, in exactly the same way as he later did it for the dog . . .
     I suggest, then, that we have in the past overlooked the fact that long before man first domesticated any other animals he domesticated himself, and he created himself thereby those very factors which we know are so potent in accelerating the effect of the natural processes of evolutionary change.
