You can spout quotes all day. That doesn't change the fact that evolution has nothing whatsoever to do with ethics. The fact that some politically-minded scientists try to force-fit it into doing so says that they are more interested in the politics than the science.
“Naturalistic evolution has clear consequences that Charles Darwin understood perfectly. 1) No gods worth having exist; 2) no life after death exists; 3) no ultimate foundation for ethics exists; 4) no ultimate meaning in life exists; and 5) human free will is nonexistent.”
-William Provine (from Darwin Day speech)
Then would you consider evolutionary psychology to be an illegitimate branch of Darwinian evolution?
