It is well-understood that the primary relationship between agents in an evolutionary system is that of competition for resources: food, mates, territory, control, etc. It is also recognized that agents not only compete but also cooperate with one another, sometimes simultaneously, for instance hunting in packs (cooperation) while also fighting for alpha status within the pack (competition). If we look at inter-agent behaviors as existing on a continuum of pure competition on one end and pure cooperation* on the other, it is clear that there is broad range both within species and between agents of different species. Originally, cooperative behavior was explained away as an exception to the general competitive landscape and happened only when two agents shared enough genetic code (such as between parent and child) that cooperation could be seen as a form of genetic selfishness. While this true in a narrow sense, it misses the larger point which is that cooperation between any two or more agents can confer advantages to all …
