Accepted: 26 May 1996
We examine the mechanism by which the Bak-Sneppen evolution model approaches the self-organized critical state and the statistical properties of the system at criticality, in particular, the gap function and the spatial-temporal correlation between successive events. Furthermore, we have undertaken extensive numerical simulation, of which the excellent data collapse explicitly affirms the dynamic scaling behavior of the statistical quantities of the system at criticality.
