Statistical mechanics of convergent evolution in spatial patterning [PDF]
Proceedings of the National Academy of Sciences, 2009 We explore how the genotype–phenotype map determines convergent evolution in a simple model of spatial gene regulation during development. Evolution is simulated via a Monte Carlo scheme that incorporates mutation, selection, and genetic drift, by using a bottom-up model of gene regulation with a fitness function that is optimized by a switch-like ...

Disease transmission promotes evolution of host spatial patterns [PDF]
Journal of The Royal Society Interface, 2016 Ecological dynamics can produce a variety of striking patterns. On ecological time scales, pattern formation has been hypothesized to be due to the interaction between a species and its local environment. On longer time scales, evolutionary factors must be taken into account.

Discerning Spatiotemporal Patterns and Policy Drivers of Rural Settlement Changes from 1962 to 2020
Land, 2022 Despite two centuries of urbanisation worldwide, 45% of the world’s people still live in rural areas. Driven by urban development, the form and structure of rural settlements have undergone drastic changes.

Wave Patterns in Spatial Games and the Evolution of Cooperation [PDF]
, 2000 Our understanding of the evolution of animal behavior has been greatly enhanced by the use of game theory (Maynard Smith 1982). Classical games assume that a given individual is equally likely to interact with any other member of the population and that the success of any individual depends on the frequency of all other strategies represented in the ...
