Mass Extinctions vs. Uniformitarianism in Biological Evolution

  title={Mass Extinctions vs. Uniformitarianism in Biological Evolution},
  author={Per Bak and Maya Paczuski},
It is usually believed that Darwin's theory leads to a smooth gradual evo lution, so that mass extinctions must be caused by external shocks. However, it has recently been argued that mass extinctions arise from the intrinsic dynamics of Dar winian evolution. Species become extinct when swept by intermittent avalanches prop agating through the global ecology. These ideas are made concrete through studies of simple mathematical models of coevolving species. The models exhibit self-organized… CONTINUE READING
