Error catastrophe is studied in a growing pattern with cellular automata. It is found that, although the critical error threshold Pc for error catastrophe decreases monotonically with decreasing diffusion coefficient D, Pc remains at a finite value in the limit that D goes to 0 because particles with higher growth rate repress the growth of those with lower growth rate spatially. The possibility that the spatial structure accelerates the evolution is also discussed.
