A model developed by evolutionary mathematicians shows that as conditions for cooperation improve between two species, mutually beneficial behavior can unexpectedly become unbalanced. Cooperative ...

Cooperative behaviour and prosociality in nonhuman primates constitute a vital area of research that illuminates the evolutionary origins of complex sociality. Studies indicate that primates employ a ...

A person who is generous and caring at home may be cutthroat at work, striving to bring in the most sales or advance up a corporate management chain. In a similar vein, a self-centered neighbor may be ...

How did cooperative behavior prevail in human evolution? Researchers have challenged two prevailing explanations -- repeated interactions on the one hand or group competition on the other. Instead, ...

Microbes often display cooperative behaviour in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, “cheater” cells in the group may reap the ...

Researchers at the Max Planck Institute in Plön show that reputation plays a key role in determining which rewarding policies people adopt. Using game theory, they explain why individuals learn to use ...

Humans regularly cooperate and share resources with other, unrelated humans in different social groups, often without any immediate, reciprocated benefits. The phenomenon has been considered unique to ...

Children across the globe engage in a constellation of behaviors that support cooperation, an action critical to the survival of the human species, a team of Boston College researchers report today in ...

The ability to cooperate plays a crucial role in many areas of human life—whether in the workplace, in politics, or in personal relationships. A new study shows how memory and the recollection of past ...

The most dreadful emotional states for all animals are feelings of vulnerability, helplessness, and powerlessness. These typically activate the threat-detection network of the brain, triggering ...

Darwin was puzzled by cooperation in nature—it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game ...
