“Evolutionary progress can be propelled both by the competitive struggle to adapt to an environment, and by the relaxation of selective forces. When natural selection on an organism is relaxed, the creative powers of mutation can be unshackled and evolution accelerated. The relief of an easier life can inspire new biological forms just as powerfully as the threat of death.” Kelly Clancy in Nautilus: It’s time to give the violent metaphors of evolution a break. Survival of the Friendliest. (If it can work in nature, maybe it can work on Twitter?)
