He argued that human altruistic behavior, as one of the human nature characteristics, is the result of the genetic inheritance.

The adaptive nature of this behavior has been supported by the analysis of theoretical models [7] [8] and also by the analyses of the behavioral repertoire of different animal species. [9] Thus, tuberculosis -infected European badgers and rabies -infected dogs equally tend to emigrate from their natal ranges before starting to distribute the ...

[1] It is a combination of altruism, defined as behavior done for the benefit of others without direct effect on the self, and parochialism, which refers ...
The green-beard effect is a form of selection in which individuals with genes that produce unique observable traits select individuals with the specific trait and thereby the same gene. In this illustration individuals selectively mate with individuals of the same head color. The green-beard effect is a thought experiment used in evolutionary ...
