Evolution: Towards a genetical theory of adaptation

The population genetic basis for adaptation has remained obscure despite a longstanding body of theory. Microbial selection experiments are beginning to provide some answers.

Towards a Theory of Evolution Strategies: Self-Adaptation

This paper analyzes the Self-Adaptation (SA) algorithm widely used to adapt strategy parameters of the Evolution Strategy (ES) in order to obtain maximal ES-performance. The investigations are concentrated on the adaptation of one general mutation strength (called SA) in (1;) ESs. The hypersphere serves as the tness model. Starting from an introduction into the basic concept of self-adaptation,...

Cognitive Evolution of the “Human” Concept and Its Adaptation to Piaget’s Theory

Background: Cognitions and attitudes, especially anthropological attitudes, are influential in human behavior. Objectives: The present study was conducted to investigate the cognitive evolution of the human concept in elementary school female students and its adaptation to Piaget’s theory of cognitive development. Materials & Methods: The present research method is qualitative of deductive-ind...

A genetical theory of species selection.

Species selection, differential rates of speciation or extinction resulting from species level characters, is often invoked as the main mechanism of macroevolution that is not simply an extension of microevolutionary processes. So long as we are careful in defining "species", the logic of species selection is sound. This does not mean, however, that this process can influence evolutionary dynam...

Towards a Statistical Theory of Texture Evolution

Under standard processing conditions, many materials possess polycrystalline microstructures composed of a large number of small monocrystalline grains separated by grain boundaries. The energetics and connectivity of the grain boundaries network plays a crucial role in defining the properties of a material across a wide range of scales. A central problem in materials science is to develop tech...
