Charles Darwin died in 1882 and his theory of Evolution was roundly condemned by many churchmen during his lifetime. But one of its moral implications is only now being realized. If man is biologically related to other animals, then it seems to me that we should also be morally related. Since Darwin, the alleged gap between man and the rest of creation can no longer be accepted for giving to man privileges and rights which are entirely withheld from the other sentient species. We are all animals and we are all cousins.
