Abstract
This discussion recounts the development of several anthropological definitions of human nature. It then examines conclusions of studies in other disciplines that make possible a revised empirical definition of human nature and which have led to re-examination of paleoanthropological data classed as unimportant under the rubrics of preceeding studies. Finally, this discussion appraises certain of these data, as they pertain to the question: "Do empirical evidences suggest that a human nature, as well as a human structure, may be the product of evolutionary processes?"
