ABSTRACT
Much of the current public interest in evolution stems from the implications it has, or is alleged to have, for human nature. Darwin was aware of the possibility that it might have such implications: “In the distant future I see open elds for far more important researches. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation. Light will be thrown on the origin of man and his history” ([1859] 1968: 458).
