Genetic similarity theory: Beyond kin selection

Genetic similarity theory: beyond kin selection.

We present genetic similarity theory (GST), which incorporates the kinselection theory of altruism under a more general principle. GST states that a gene ensures its own survival by acting so as to bring about the reproduction o f any organism in which copies of itself are to be found. Rather than behaving altruistically only toward kin, organisms are able to detect other genetically similar or...

Kin Selection with Twin Genetic Programming

In steady state Twin GP both children created by sub-tree crossover and point mutation are used. They are born together and die together. Evolution is little changed. Indeed fitness selection using the twin’s co-conceived doppelganger is possible.

The genetical theory of kin selection.

Natural selection operates both directly, via the impact of a trait upon the individual's own fitness, and indirectly, via the impact of the trait upon the fitness of the individual's genetically related social partners. These effects are often framed in terms of Hamilton's rule, rb - c > 0, which provides the central result of social-evolution theory. However, a number of studies have question...

Natural selection. VII. History and interpretation of kin selection theory.

Kin selection theory is a kind of causal analysis. The initial form of kin selection ascribed cause to costs, benefits and genetic relatedness. The theory then slowly developed a deeper and more sophisticated approach to partitioning the causes of social evolution. Controversy followed because causal analysis inevitably attracts opposing views. It is always possible to separate total effects in...
