Agent based simulation is a powerful tool for the research of complex systems such as human society. The important key word of this kind of research is “bounded rationality” of the agents. From the standpoint, we adopt following two hypotheses as the basis of our analysis: (1) each agent interacts only with his neighbors, and (2) each agent behaves by mimicking its neighbors. How the society gr...

Microbial ecology is revealing the vast diversity of strains and species that coexist in many environments, ranging from free-living communities to the symbionts that compose the human microbiome. In parallel, there is growing evidence of the importance of cooperative phenotypes for the growth and behavior of microbial groups. Here we ask: How does the presence of multiple species affect the ev...

Social norms are patterns of behavior that are self-enforcing at the group level: everyone wants to conform when they expect everyone else to conform. There are multiple mechanisms that sustain social norms, including a desire to coordinate, fear of being sanctioned, signaling membership in the group, or simply following the lead of others. This article shows how stochastic evolutionary game th...

We propose substantive universals in the relationship between social evolution and language change. Social anthropologists have categorized societies into roughly four broad types by social organization: bands, tribes, chiefdoms and states. This classification is evolutionary in the sense that the society types arose in human history in the sequence given above. We compare these society types t...

For several years the study of social behavior has been undergoing a revolution with far-reaching consequences for the social and biological sciences. Partly responsible are three recent changes in the attitudes of evolutionary biologists. First was grow­ ing acceptance of the evidence that the potency of natural selection is overwhelm­ ingly concentrated at levels no higher than that of the in...

Understanding of evolutionary mechanism of online social networks is greatly significant for the development of network science. However, present researches on evolutionary mechanism of online social networks are neither deep nor clear enough. In this study, we empirically showed the essential evolution characteristics of Renren online social network. From the perspective of Pareto wealth distr...

The purpose of this article is to analyse the way economists interested in social and economic evolution cite, mention or refer to Darwin. We focus on the attitude of economists towards Darwin’s theory of social evolution – an issue he considered as central to his theory. We show that economists refer to and mention Darwin as a biologist and neglect or ignore his theory of social and cultural e...

A close observation of Iran-Iraq war films in the Iranian society reveals that their genres have shifted in the course of the society’s evolution. This questions the category-based principles of genre we have known so far in literature concerning film theory and necessitates a new conceptualization of genre, which can be realized with the aid of Niklas Luhmann’s social systems theory. This theo...
