Resumo

In this work, we outline a mathematical description of biodiversity evolution throughout the Phanerozoic based on a simple coupled system of two differential equations and on the division of genera in two classes-Short-lived and Long-lived types, as used by Rohde and Muller. We show that while the division in only two classes cannot capture the complexity of biodiversity evolution in short scales, broad trends can be described well. We also compute the systems' Green functions as a way to qualitatively describe the possible effects of intense perturbations of astrophysical origin on the subsequent biodiversity evolution. (AU)
