Islands are natural workshops of evolution.

Things exist either because they have recently come into existence or because they have qualities that made them unlikely to be destroyed in the past.

There was something built into the human brain by natural selection which was once useful, and which now manifests itself as religion.

The chicken is only an egg’s way for making another egg.

The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored. In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won't find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.

Even if it were true that evolution, or the teaching of evolution, encouraged immorality that would not imply that the theory of evolution was false.
