Consequently, initial publications that offered solutions to subsets of the observed cases of helping, such as kin selection (Hamilton, 1964) or reciprocity (Axelrod & Hamilton, 1981; Trivers, 1971), are among the most influential and most cited papers in evolution / behavioural ecology. Despite these initial successes, models …
