Wild animal suffering nature would be either unethical, unfeasible, or both. In his autobiography, Charles Darwin acknowledged that the existence of extensive suffering in nature was fully compatible with the workings of natural selection, yet maintained that pleasure was the main driver of fitness-increasing behavior in organisms. Evolutionary biologist Richard Dawkins challenged Darwin's claim in his book "River Out of Eden", wherein he argued that wild animal suffering must be extensive due to the interplay of the following evolutionary mechanisms: From this, Dawkins concludes that the natural world must necessarily contain enormous amounts of animal suffering as an inevitable consequence of Darwinian evolution.
