The paper explores the significance of Darwinian evolution for morality and moral theory. After presenting Darwin’s own views on the evolution of the moral sense and the Victorian spectrum of opinion on the relevance of natural selection to morals, I argue that a consideration of human evolutionary history can be brought to bear meaningfully on a number of contemporary issues, including the ...
The basic theory of evolution is surprisingly simple. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate.
