Nautilus: “…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. One of the best ways to relax selective forces is to work together, something that mathematical biologist Martin Nowak has called the “snuggle for survival.” New research has only deepened and broadened the importance of cooperation and lifting of selective pressures. It’s a big, snuggly world out there…Evolution is not a weapons race, but a peace treaty among interdependent nations…”
