Abstract
We study the information transfer model for biological evolution with several kinds of fitness function. The system is stimulated to volve into a stationary state, depending on the fitness function and on the dimension of the lattice formed by the species. In particular the system yields time series of the mutation rate which exhibits the spectrum, thus explains the power-law behavior in fossil data. Effects of shortcuts introduced on the lattice are also examined and the evolution activity is usually found to increase in a well-growing system although the reduction of the overall activity may also be observed in the presence of shortcuts, depending on the initial configuration.
