The influence of the moving rate of raw materials in the solution on the competition between the protocell subsystem and the naked subsystem. The black-line case is the same as the blue-line case in Fig. 14. When the moving rate of raw materials in the solution region is increased to 0.0002 (the yellow line), both the ribozymes within protocells in the solution region and the naked ribozymes in the rocky region are benefited due to their greater accessibility to the raw materials (the naked ribozymes in the rocky region are also benefited because raw materials in the solution region may diffuse into the rocky region). However, when the moving rate of raw materials in the solution region increases further (the orange and red lines), the ribozymes within protocells (or say, the protocell subsystem) may win the superiority because they, no matter how, benefit from this “condition change” more directly
