Abstract
We study two variants of a binary model for Darwinian Coevolution in an ecosystem of interacting
species based on a model recently proposed by Bak and Sneppen [1]. We present results from a
computer simulation and an improved mean-field calculation, including exponents, critical points and
probability of certain spin configurations.
