 Briefly, the argument is that because replicators are the only entities that “survive” the evolutionary process, they must be the beneficiaries (Dawkins 1982a,b). What happens in the process of evolution by natural selection happens for their sake, for their benefit. Hence, interactors interact for the replicators’ benefit, and adaptations belong to the replicators. Replicators are the only entities with real agency as initiators of causal chains that lead to the phenotypes; hence, they accrue the credit and are the real units of selection.
