kin selection

n.
A biological theory stating that a gene that causes an organism to exhibit behavior detrimental to its survival will increase in frequency in a population if that behavior benefits the organism's relatives, which will pass the gene on to subsequent generations.

kin selection

n
(Biology) biology natural selection resulting from altruistic behaviour by animals towards members of the same species, esp their offspring or other relatives

He offers several models of social behavior, discusses the Price equation and Hamilton's Rule at length, and keeps to the understanding that inclusive fitness theory extends Darwinism and classic evolutionary theory.
Known as Hamilton's rule of kin selection, the theory simply states that whether or not an organism shares its food with another depends on its genetic closeness (how many genes it shares) with the other organism.
The groups that shared along the lines of Hamilton's rule foraged better and passed their code onto the next generation.
The quantitative results matched surprisingly well the predictions of Hamilton's rule even in the presence of multiple interactions.
In a crisis, say Sylla and his coauthors, Hamilton's rule was "Act first, explain later"
Formally known as Hamilton's rule of kin selection, Hamilton's core finding was that a gene for altruism can evolve in a population, providing:
Hamilton's rule has been a foundation stone of modern evolutionary biology and the study of animal behaviour for nearly half a century (e.
2003): none meet the crucial criterion necessary for a formal test of Hamilton's rule (that the altruist pays a personal cost).
A model based on Hamilton's rule is presented for explaining competence in multiple generations.
I show the power of this formalism by clarifying two aspects of Hamilton's rule of kin selection.
On the other side, various exceptions to Hamilton's rule have been given (reviewed by Seger 1981; Michod 1982; Grafen 1985; Queller 1992a,b).
Here I analyze the logical status of Hamilton's rule with the exact Price Equation.
