# An Entropic Model of Gaia

## TL;DR

This paper introduces an entropic model of Gaia by modifying an existing ecological model to include species-environment interactions, highlighting the role of entropy in biological and environmental co-evolution.

## Contribution

It presents a novel entropic framework for Gaia, extending the Tangled Nature Model to incorporate effects of life on carrying capacity and environmental feedback.

## Key findings

- The model shows systems tend to increase carrying capacity with life.
- It demonstrates a hierarchy driven by entropy in ecological systems.
- Implications for Gaia theory and Earth's self-regulating processes.

## Abstract

We modify the Tangled Nature Model of Christensen et. al. so that the agents affect the carrying capacity. This leads to a model of species-environment co-evolution where the system tends to have a larger carrying capacity with life than without. We discuss the model as an example of an entropic hierarchy and some implications for Gaia theory.
