Envy/Jealousy Tendency A member of a species designed through evolutionary process to want often scarce food is going to be driven strongly toward getting food when it first sees food. And this is going to occur often and tend to create some conflict when the food is seen in the possession of another member of the same species. This is probably the evolutionary origin of the envy/jealousy tendency that lies so deep in human nature. —CHARLIE MUNGER, UNIVERSITY OF SOUTHERN CALIFORNIA (USC), 1994
