Connectivity and catastrophe-towards a general theory of evolution

  title={Connectivity and catastrophe-towards a general theory of evolution},
  author={David G. Green and David Newth and M. Kirley}
Here we show that connectivity and catastrophe play a key role in driving species evolution within a landscape. They also form a special case of a more general process, which occurs widely in natural and artifical systems. In this process, catastrophes cause a temporary phase change in the connectivity of a system. Different mechanisms (selection and variation) predominate in each phase. The system passes through the critical point without being poised there. The “chaotic edge” associated with… CONTINUE READING
