Effective cooperation does not require trust among animals

Evidence

These questions about the evolution of cooperation do not bear directly on the issue of trust, though they may give pause to anyone who supposes that trust is required for effective cooperation (defined simply in terms of working with and assisting others). To maintain such a position it would be necessary to argue that, for example, honey bees trust each other. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 245
