Sensitivity to initial conditions in coherent noise models

Abstract

Sensitivity to initial conditions in the coherent noise model of biological evolution, introduced by Newman, is studied by making use of damage spreading technique. A power-law behavior has been observed, the associated exponent $\alpha$ and the dynamical exponent $z$ are calculated. Using these values a clear data collapse has been obtained.
