Thinking about evolutionary mechanisms: natural selection.
This paper explores whether natural selection, a putative evolutionary mechanism, and a main one at that, can be characterized on either of the two dominant conceptions of mechanism, due to Glennan and the team of Machamer, Darden, and Craver, that constitute the new mechanistic philosophy'. The results of the analysis are that neither of the dominant conceptions of mechanism adequately capture...
متن کاملEvolutionary games: natural selection of strategies
In this paper, I model and study the process of natural selection between all possible mixed strategies in classical two-player two-strategy games. I derive and solve an equation that is a natural generalization of the Taylor-Jonker replicator equation that describes dynamics of pure strategy frequencies. I then investigate the evolution of not only frequencies of pure strategies but also of to...
متن کاملRemarks on the evolutionary effect of natural selection.
The so-called "Fundamental Theorem of Natural Selectiion", than the mean fitness of a population increases with time under natural selection, is known not to be true, as a mathematical theorem, when fitnesses depend on more than one locus. Although this observation may not have particular biological relevance, (so that mean fitness may well increase in the great majority of interesting situatio...
متن کاملNatural selection. III. Selection versus transmission and the levels of selection. Journal of Evolutionary Biology
Natural selection increases inherited information about environmental challenge. Against selection, imperfect transmission reduces inherited information. Many problems in biology come down to understanding the relative balance between selection and imperfect transmission. A clear understanding of selection and transmission requires greater precision with regard to abstract notions such as inher...
متن کاملEvolutionary capacitance may be favored by natural selection.
Evolutionary capacitors phenotypically reveal a stock of cryptic genetic variation in a reversible fashion. The sudden and reversible revelation of a range of variation is fundamentally different from the gradual introduction of variation by mutation. Here I study the invasion dynamics of modifiers of revelation. A modifier with the optimal rate of revelation mopt has a higher probability of in...
