Evolutionary branching in complex landscapes.
Divergent adaptation to different environments can promote speciation, and it is thus important to consider spatial structure in models of speciation. Earlier theoretical work, however, has been limited to particularly simple types of spatial structure (linear environmental gradients and spatially discrete metapopulations), leaving unaddressed the effects of more realistic patterns of landscape...
متن کاملAdaptation in simple and complex fitness landscapes
The notion that evolution can be viewed as a hill-climbing process in an adaptive landscape was introduced in 1932 by Sewall Wright [1], and remains one of the most powerful images in evolutionary biology [2]. Since the discovery of the molecular structure of genes it has been clear that the substrate over which the adaptive landscape should be properly defined is the space of genetic sequences...
متن کاملMemory distribution in complex fitness landscapes
In a co-evolutionary context, the survive probability of individual elements of a system depends on their relation with their neighbors. The natural selection process depends on the whole population, which is determined by local events between individuals. Particular characteristics assigned to each individual, as larger memory, usually improve the individual fitness, but an agent possess also ...
متن کاملCritical Properties of Complex Fitness Landscapes
Evolutionary adaptation is the process that increases the fit of a population to the fitness landscape it inhabits. As a consequence, evolutionary dynamics is shaped, constrained, and channeled, by that fitness landscape. Much work has been expended to understand the evolutionary dynamics of adapting populations, but much less is known about the structure of the landscapes. Here, we study the g...
متن کاملComplex network analysis of free-energy landscapes.
The kinetics of biomolecular isomerization processes, such as protein folding, is governed by a free-energy surface of high dimensionality and complexity. As an alternative to projections into one or two dimensions, the free-energy surface can be mapped into a weighted network where nodes and links are configurations and direct transitions among them, respectively. In this work, the free-energy...
