Schicht- und klassenspezifisches Verhalten,equently wish to investigate the evolution of traits across a range of species. This is known as a comparative study. Comparative studies require constructing a phylogeny of the species and then investigating the evolutionary transitions in the trait on that phylogeny. A difficulty with this approac

Landscape theory has emerged as an attempt to devise suitable mathematical structures for describing the “static” properties of landscapes as well a

In this limit the population is always localized at a single temporary master sequence ., and we study the statistical properties of the evolutionary trajectory

This dynamics acts as a selection mechanism, which can lead to the extinction of species. Adaptive changes of the interactions or the generation of new species in
