One specific human trait that has evolved through natural selection is our capacity for complex social cooperation. The adaptive advantage of this trait lies in the ability to form and maintain intricate social structures, fostering collaboration and mutual support within groups. This cooperative behavior enhances collective survival by allowing humans to work together for common goals, share resources, and provide protection. It has contributed to the success of the human species by promoting group cohesion, which in turn aids in securing food, defending against threats, and nurturing the young, ultimately increasing the likelihood of individual and group reproductive success.
