Species expand their geographical ranges following an environmental change , long range dispersal , or a new adaptation . Range expansions not only bring an ecological change , but also affect the evolution of the expanding species . Although the dynamics of deleterious , neutral , and beneficial mutations have been ex... | Cooperation is beneficial for the species as a whole , but , at the level of an individual , defection pays off . Natural selection is then expected to favor defectors and eliminate cooperation . This prediction is in stark contrast with the abundance of cooperation at all levels of biological systems: from bacterial b... | [
