ALTRUISM IN MENDELIAN POPULATIONS DERIVED FROM SIBLING GROUPS: THE HAYSTACK MODEL REVISITED - David Sloan Wilson, Evolution. 41(5), 1987, pp. 1059–1070
Abstract.- A group-selection model is presented in which each group isinitiated by a single fertilized female and persists for several generations before dispersal. Maynard Smith (1964) concluded that altruism could not plausibly evolve under these circumstances. I show that his conclusion is an artifact of a simplifying assumption that amounts to a worst-case scenario for group selection. When the standard donor-recipient equations for altruistic behavior are used in Maynard Smith’s model, Mendelian populations derived from sibling groups are often more favorable for the evolution of altruism than are the sibling groups themselves. In general, long-term and large-scale aspects of population structure may at times be important in the evolution of altruistic and other group-advantageous behaviors.
Cheaters and Cheater Detection
Pull quote from On Human Nature: “The buzz of conversation is a constant background to the camp’s activities: there is an endless flow of talk about gathering, hunting, the weather, food distribution, gift giving, and scandal. No !Kung is ever at a loss for words, and often two or three people will hold forth at once in a single conversation, giving the listeners a choice of channels to tune in on. A good proportion of this talk in even the happiest of camps verges on argument. People argue about improper food distribution, about breaches of etiquette, and about failure to reciprocate hospitality and gift giving… almost all the arguments are ad hominem. The most frequent accusations heard are of pride, arrogance, laziness, and selfishness.
