After Charles Darwin published his theory of Natural Selection, he continued to reflect on what he had observed in the living world. A decade later he proposed a second major evolutionary mechanism: Mating Choice or Sexual Selection. Most of us are not familiar with this later theory, because it was suppressed by the male-dominated world of science: it places females in a central role in evolution. In recent years the study of Mating Choice has produced remarkable insights into the human condition, including the notion that ethical teachings can change the evolution of human behavior.
