Cooperation is one of the elements that form the foundation of social systems; nonetheless, the intricacies of its evolutionary mechanisms are not fully understood. Recently, "multiplex networks" have ...

The spatial structure of genetic diversity underlying social variation is a critical determinant of how cooperation and conflict evolve. Here we investigated whether natural social groups of the ...

Cooperation is a guiding principle of everyday life. It’s as simple as following the rules of the road when driving or holding a door for a stranger; cooperation is a fundamental aspect of human ...

Researchers have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory. This result offers a new ...

Cooperation has been a more important evolutionary jorce in the development of man than has the bitter competitive struggle for existence. So asserted a learned U.S. biologist last week in an attack ...

Every two minutes or so, all over the world, someone asks someone else for a small favor. Pass the salt, wipe the counter, turn on the light — the microscale transactions of daily life. No big deal, ...

Evolutionary principles for cooperation that have been developed from studies of diverse social organisms should apply to humans. The more immediate roots to human cooperation and conflict also may be ...

Tsukuba, Japan—Previous scholars have widely proposed that the emergence of advanced cognitive abilities and sociality in humans originated in Africa during the MSA. However, the specific mechanisms ...
