GenePool: Exploring The Interaction Between Natural Selection and Sexual Selection

Gene Pool is an artificial life simulation designed to bring some basic principles of evolution to light in an entertaining and instructive way. Most significant is the aspect of sexual selection — where mate choice is a factor in the evolution of morphology and motor-control in physically-based animated organisms. We see in the examples of deer antlers, peacock tails, and fish coloration a mag...

On Theoretical Models of Gene Expression Evolution with Random Genetic Drift and Natural Selection

BACKGROUND The relative contributions of natural selection and random genetic drift are a major source of debate in the study of gene expression evolution, which is hypothesized to serve as a bridge from molecular to phenotypic evolution. It has been suggested that the conflict between views is caused by the lack of a definite model of the neutral hypothesis, which can describe the long-run beh...

Genetic drift in genetic algorithm selection schemes

A method for calculating genetic drift in terms of changing population fitness variance is presented. The method allows for an easy comparison of different selection schemes and exact analytical results are derived for traditional generational selection, steady-state selection with varying generation gap, a simple model of Eshelman’s CHC algorithm, and (μ + λ) evolution strategies. The effects ...

Optimizing Self-Organizing Control Architectures with Genetic Algorithms: The Interaction Between Natural Selection and Ontogenesis

To model the relationship between natural selection and ontogenesis, techniques from genetic algorithms and neural networks can be combined. We model this interaction as two complementary processes were the adaptation of the individual takes place to adjust to properties of the system environment interaction that cannot be predicted from the perspective of the genome. Adaptation of the individu...

Natural Selection and Genetic Drift: An Exploration of Allele Frequencies Within a Population

An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. Because each person’s genome contains two copies of each chromosome (one from his father and one from his mother), each individual has two alleles for each gene. These alleles may be the same or they may be different from one another (Figure 1). In this study, we u...
