Evolutionary fitness

Rutter In my introductory remarks I expressed scepticism about whether the correlations for social success and so on were relevant to this issue. What value is there in thinking about g in relation to evolutionary fitness ...

Evolutionary fitness. Suppose that the probability of having the dominant allele (D) in a gene is p and the probability of the recessive allele (R) is tj = 1 - p. You have two alleles, one from each parent. 

The formation of the encapsulating membranes is discussed by Turk-MacLeod et al. the operative strictures of thermodynamics in these processes and in the functional role of cell membranes are elaborated. The competition between vesicles that encapsulate RNA and those incapable of doing so, considered as model protocells, and its relation to the evolutionary fitness of replicator functions, is considered at length in terms of the driving forces of thermodynamics. It is noted that membrane stabilization is a key objective in this competition but this results also in a reduction of permeability, thus diminishing the ability of the protocell to use nutrients. Further evolution of the membrane and its constituents is necessary to overcome this restriction in function. In this respect it is of interest that model protocell membranes composed of particular mixtures of amphiphiles have superior... 

The processes of evolution have been remarkably successful in creating animals that are well adapted to their environment. By continually adjusting the population through genetic mutation, evolutionary change works toward the perfect individual to fill a particular environmental niche. Not every new individual is well suited to its environment, of course, and the fitness of new individuals is repeatedly tested as the animals try to survive, prosper, and reproduce. 

Termination criteria usually combine two terms one relating to the actual ultimate objective of the exercise, such as a perfectly fitting function and another term setting an upper limit on the number of generations that the evolutionary algorithm can run. 

Each individual results in a genome capable of developing into a fully grown individual. After development, the fitness can be calculated and the evolutionary process gets its feedback. The following example explains the development process of a "good" individual evolved by Dellaert.10... 

Representation requires that the designer of a typical evolutionary computation algorithm (EA) formulates one inadaptable blueprint for the solution of some problem, then present the variables of that blueprint in a form that is amenable to manipulation by the genetic operators of the EA. Fitness evaluation, on the other hand, has limited GA in two distinct ways (1) it has limited environmental feedback to the confines of a formula or algorithm, which reflects accurately and exclusively the quality of the complete candidate solution from the perspective of the human designer. In addition, (2) fitness evaluation has proven to be the most computationally costly part of a typical EA. Note that elaborate developmental mappings actually increase that computational cost. However, our interest here lies in the limiting effects of representation. 

When evolution selects the genes that build the parts of brains (modules) that produce a particular kind of behaviour, and evolution selects them because of the fitness benefits of that kind of behaviour, we have the conditions for a perfect evolutionary psychological explanation.
