Sex ratio evolution through group selection using diffusion approximation.
We consider a haploid, hermaphrodite population subdivided into an infinite number of demes of finite size N. Assuming recurrent mutation, random union of gametes, partial dispersal, genetic drift, and incorporating group competition, a diffusion approximation is used to describe the evolution of sex ratio, corresponding to sex allocation to male versus female functions. The stationary distribu...
متن کاملGroup selection models in prebiotic evolution.
The evolution of enzyme production is studied analytically using ideas of the group selection theory for the evolution of altruistic behavior. In particular, we argue that the mathematical formulation of Wilson's structured deme model [The Evolution of Populations and Communities (Benjamin-Cumings, Menlo Park, 1980)] is a mean-field approach in which the actual environment that a particular ind...
متن کاملAnalysis of evolution through competitive selection.
Recent studies of in vitro evolution of DNA via protein binding indicate that the evolution behavior is qualitatively different in different parameter regimes. I here present a general theory that is valid for a wide range of parameters, and which reproduces and extends previous results. Specifically, the mean-field theory of a general translation-invariant model can be reduced to the basic dif...
متن کاملEvolution of social behavior through interpopulation selection.
Under certain special conditions natural selection can be effective at the level of local populations, or demes. Such interpopulation selection will favor genotypes that reduce the probability of extinction of their parent population even at the cost of a lowered inclusive fitness. Such genotypes may be characterized by altruistic traits only in a viscous population, i.e., in a population in wh...
متن کاملEvolution of Social Behavior: Individual and Group Selection
If we were told that a man lived a long and prosperous life in the world of Chicago gangsters, we would be entitled to make some guesses as to the sort of man he was . . . . Like successful Chicago gangsters, our genes have survived, in some cases for millions of years, in a highly competitive world . . . . If you look at the way natural selection works, it seems to follow that anything that ha...
