We discuss fitness landscapes and how they can be modified to account for co-evolution. We are interested in using the landscape as a way to model rational decision making in a toy economic system. We develop a model very similar to the Tangled Nature Model of Christensen et al. that we call the Tangled Decision Model. This is a natural setting for our discussion of co-evolutionary fitness landscapes. We use a Monte Carlo step to simulate decision making and investigate two different decision… Expand

Selection Principles for Gaia
The Gaia hypothesis discusses how life interacts with the environment to create generally favourable conditions for itself. In this paper we discuss three mechanisms which could potentially lead toExpand
An entropic model of Gaia.
TLDR
The Tangled Nature Model is modified so that the agents affect the carrying capacity, leading to a model of species-environment co-evolution where the system tends to have a larger carrying capacity with life than without. Expand
Human-Nature Relations: The Unwanted Filibuster
Human–nature relations encompass many of the age-old questions about our existence, place, and time. This chapter explores some of these notions and offers insight into the question “why protectExpand

Coevolution to the edge of chaos: coupled fitness landscapes, poised states, and coevolutionary avalanches.
TLDR
The results suggest that sustained fitness is optimized when landscape ruggedness relative to couplings between landscapes is tuned such that Nash equilibria just tenuously form across the ecosystem. Expand

TLDR
This work focuses on the evolution of yeast and Drosophila genomes, providing examples where adaptive evolution can and cannot be inferred, despite the presence of positive selection. Expand

TLDR
A new framework is emerging for deepening the understanding of evolution and speciation, which provides a plausible multidimensional alternative to the conventional view of rugged adaptive landscapes. Expand

We discuss a simple model of co-evolution. In order to emphasize the effect of interaction between individuals, the entire population is subjected to the same physical environment. Species areExpand
Diversity as a product of inter-specific interactions.
We demonstrate diversification rather than optimization for highly interacting organisms in a well-mixed biological system by means of a simple model of coevolution. We find the cause to be theExpand
The Tangled Nature model with inheritance and constraint: Evolutionary ecology restricted by a conserved resource
TLDR
A version of the Tangled Nature model of evolutionary ecology redefined in a phenotype space where mutants have properties correlated to their parents is studied, observing that the mean lifetime is inversely related to the resource level. Expand
The NK model of rugged fitness landscapes and its application to maturation of the immune response.
TLDR
This work analyzes a class of mathematical models the authors call NK models and shows that these models capture significant features of the maturation of the immune response, which is currently thought to share features with general protein evolution. Expand
Adaptation on rugged landscapes
A simple model is developed to explore the interrelationship between processes of organizational level change and population selection forces. A critical property of the model is that the effect onExpand
The species-area relationship and evolution.
TLDR
It is found that long-lasting co-evolutionary habitats form, allowing high diversity levels in a spatially homogenous system and producing power-law species-area relations as observed in ecological measurements at medium scales. Expand

TLDR
A quantitative dynamical effect of trait inheritance is found, namely, that increasing the value of K numerically decreases the decay exponent of the species survival probability. Expand
