Sociobiology of the myxobacteria.
Cooperation is integral to much of biological life but can be threatened by selfish evolutionary strategies. Diverse cooperative traits have evolved among microbes, but particularly sophisticated forms of sociality have arisen in the myxobacteria, including group motility and multicellular fruiting body development. Myxobacterial cooperation has succeeded against socially destructive cheaters a...
متن کاملEstimating Seven Coefficients of Pairwise Relatedness Using Population-Genomic Data.
Population structure can be described by genotypic-correlation coefficients between groups of individuals, the most basic of which are the pairwise relatedness coefficients between any two individuals. There are nine pairwise relatedness coefficients in the most general model, and we show that these can be reduced to seven coefficients for biallelic loci. Although all nine coefficients can be e...

The new field of evolutionary sociology is the product of recent efforts by sociologists to integrate sociobiological reasoning into their theoretical thinking and empirical research. Evolutionary sociologists reject the Standard Social Science Model of human nature and human social ...
