We're in this together: A pathbreaking investigation into the evolution of cooperative behavior
Date:11/19/2012

od partnerswho were able to coordinate well with their fellow foragers and would pull their weight in the groupwere more likely to succeed.

As societies grew in size and complexity, their members became even more dependent on one another. In what the authors of this study define as a second evolutionary step, these collaborative skills and impulses were developed on a larger scale as humans faced competition from other groups. People became more "group-minded," identifying with others in their society even if they did not know them personally. This new sense of belonging brought about cultural conventions, norms, and institutions that incentivized and structured feelings of social responsibility.
