Summary
Selection operates at group level within a species through group competition; group with a larger population size (for a fixed resource area) wins out
Cooperation based on relation concepts with individuals linked via a reciprocal relationship
Size of interconnected cooperating group depends on the cardinality of the set of relations
Generative relation set only requires a few rules that can generate a large number of relations
All individuals learning the generative relation set will know the same relations; all individuals sharing the same generative relation set will be pairwise linked as cooperators
Group fitness via competition selects for large, coherent set of relations, hence group competition leads to a generative set of relations
Fitness is a feature of a set of relations and the magnitude of the fitness value of a set of relations is proportional to group size entailed by sharing that set of relations; that is, fitness is measured by group competition success
Species implication: species partitioned into cooperative groups sharing the same set of relations
