Edward O. Wilson Kin Selection as the Key to Altruism: Its Rise and Fall ONE OF THE ENDURING UNSETTLED ISSUES OF EVOLUTIONARY BIOLOGY is the paradox of collateral altruistic behavior - that is, when some individuals subordinate their own interests and those of their immedi-ate offspring in order to serve the interests of a larger group beyond
Apr 28, 2011 · Wilson resolved the paradox by drawing on the theory of kin selection. According to this way of thinking, “altruistic” individuals could emerge victorious because the genes that they share with kin would be passed on. Since the whole clan is included in the genetic victory of a few, the phenomenon of beneficial altruism came to be known as ...
May 22, 2019 · Newsletter. In 1975 Harvard biologist E. O. Wilson published Sociobiology, perhaps the most powerful refinement of evolutionary theory since On the Origin of Species. Darwin’s theory of natural selection postulated a brutal world in which individuals vied for dominance. Wilson promoted a new perspective: Social behaviors were often ...

The most extreme examples of altruism in nature come from social insectssuch as bees and ants, in which workers toil endlessly for their colony but don’t reproduce themselves. Their existence had long puzzled biologists. Darwin considered social insects a potentially “insuperable difficulty” for his theory of natural selection. After all, how can s...
Hamilton’s ideas and their subsequent embellishments are now often referred to as “kin selection”, a term coined not by Hamilton but by British evolutionary biologist John Maynard Smith in 1964. Maynard Smith credited British biologist JBS Haldaneas the first to have come up with the notion of kin selection. According to rumour, Haldane declared, i...
Hamilton’s rule specifies the conditions under which a gene causing altruism might enjoy an inclusive fitness advantage. This occurs when the benefits, b, to a related individual exceed the costs, c, to the altruist, discounted by the relatedness, r, between the two: Evolutionary biologists consider this equation every bit as important as Einstein’...
In 2010, a Nature paperby Martin Nowak, Corina Tarnita and Edward O. Wilson – the latter a once-staunch supporter of kin selection and a mentor to Hamilton – rejected kin selection outright. Nowak and his co-authors claimed kin selection was simply an unnecessary reformulation of natural selection. They argued that altruistic genes can increase in ...
Kin selection provides one of the two strong forces that bind all cooperative enterprise. The other is reciprocity. Think of the first as “blood is thicker than water” and the second as “you scratch my back and I’ll scratch yours”. We rely so much on reciprocity in contemporary society, with reciprocation made liquid by money and other currencies. ...
maintained by indirect selection. The theories of kin se-lection and of parent-offspring conflict, in particular, have been the focus of adaptationist explanations. In the kin-selection hypothesis, homosexuals altruistically forgo reproduction to assist the offspring of relatives (Wilson 1975, Weinrich 1987a). In the parental-manip-

Jun 1, 2013 · For Wilson, the whole concept of natural selection acting on a group appeared superfluous when viewed through the lens of kin selection (see Figure 4). 64 Moreover, the two differed on the role of innate instinct and the environment in that Allee stressed that latter over the former whereas Wilson did the opposite.
