Formation of species diversity due to self-organized criticality — •K. Morawetz1,2, N. Amecke1, R. Radünz1, M. Döring1, and M.

The occurrence of species diversity due to a change in environmental conditions is simulated by a slight modification of the Bak-Sneppen model. We find that the forced separation of individuals leads to a separation of mutation probabilities and consequently to a bifurcation of the specie.
