“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)
The theory of evolution, like every other scientific theory, is amoral in the strictest sense. It tells us nothing as to how we should live our lives.
