A simple example of branching process is used to estimate the probability that a slightly advantageous mutation would become extinct in the population, a probability that, as expected, is proved to be one for a disadvantageous mutation but also for a

Long-term co-evolution of male's sexual extravagance and female's preference for it is studied. Fisher's ``Sexy Son'' principle is checked against Zahavi's Handicap Principle. It is shown that although both principles are equally likely to explain th

A model for a population-game with multiple asymmetry is studied, in which the participants are assumed to be different from one another both in size and in status as owners or non-owners of a territory. Only owners can reproduce, hence natural selec

In a population with a local interaction structure, where individuals interact with their neighbors and learning is by way of imitating a successful neighbor, cooperation is shown to be a stable strategy that cannot easily be eliminated from the popu

The paper provides an explanation for altruistic behavior based on the matching and learning technology in the population. In a infinite structured population, in which individuals meet and interact with their neighbors, individuals learn by imitatin

An owner-intruder conflict is analysed. While the Evolutionary Stable Strategies of both owner and intruder depend on the reproductive value of holding a territory or on the chance of getting one (Grafen, 1987), the values (and, therefore, the releva

A long-term selection, three-locus diploid model is developed in order to analyze the joint evolution of the primary sex ratio among offspring, parental manipulation, and offspring response to parental manipulation when the cost of rearing a male off

The phenomenon of group escape cannot be explained by an argument of risk dilution, applied to gregarious behaviour of passive prey whose risk of predation is equally shared by all group members (Hamilton, 1971). Instead, individuals at the tail of a

A two-locus diploid model is developed in order to analyze stable mother's and offsprings' strategies concerning the offsprings' sex determination and progeny's sex ratio when the cost of rearing a male offspring is different from the cost of rearing

This note concerns a one locus, two allele, random mating diploid population, subject to frequency-dependent viability selection. It is already known that in such a population, any evolutionarily stable strategies (ESS), if only accessible by the gen
