The evolution of cooperation ranks among the most fundamental questions of biology. The reason why our understanding of the evolution of cooperation is still unsatisfactory is the superficial appreciation of involved mechanisms. The continuing controversy over the utility of simplistic kin selection arguments and unsatisfactory alternative concepts reveals the urgent need for an approach testing alternative explanations in combined fashion. Cooperation, like other functional categories of behaviour, is an emergent property of evolved decision rules; only clarification of processes underlying these rules will advance our understanding of the evolutionary mechanisms responsible for cooperative behaviour in the real world. Typically, cooperation originates by an interaction of several evolutionary mechanisms, especially involving kin selection, negotiation and trading. Hence, the relative importance of these mechanisms and their potential interaction are of paramount significance. Here I address these alternative evolutionary mechanisms of cooperation with an experimental study on two specially suited model systems exhibiting high levels of sociality and cooperation: wild-type Norway rats and cooperative cichlids. The significance of relatedness will be scrutinized for the rules of negotiation and trading applied by social partners. We shall focus on the crucial components of Hamilton’s rule of cooperation when asking for the importance of (i) asymmetries for the negotiation process; (ii) behavioural specialization between group members when trading different commodities and service against each other; (iii) the identity and familiarity of social partners for social decisions; and (iv) time delays between subsequent interactions. Further, we aim to reveal underlying causal mechanisms and potential fitness effects of decisions of cooperation made in the experimental context. The simultaneous experimental manipulation in this project of two fundamental sources of fitness, relatedness and reciprocity, aims at improving our general understanding of the relative importance of direct and indirect fitness to the evolution of cooperation.
