Evolution of cooperation

Evolution of cooperation refers to how and why organisms developed the ability to work together for mutual benefit, even though natural selection typically favors individuals that prioritize their own survival. Scientists study this puzzle by examining how cooperative behaviors—like parents caring for offspring, animals hunting in groups, or even cells working together in multicellular bodies—became so common and successful in nature. Through mechanisms like reciprocal altruism, kin selection, and reputation, cooperation proved to be such a powerful strategy that it shaped the evolution of countless species, including humans.
