图1 不同参数标准下的最优演化路径(改编自Traulsen et al, 2007)。演化过程的起始状态为A, 经过一段时间后到达状态B, 其中红线是从A到B最先达到的路经, 即该路径所用时间最短; 蓝线表示两个状态之间距离最短的路径; 绿线表示演化过程中资源利用率最高的路径; 灰线则代表生物状态演化过程中路径依赖选择的路径。

Fig. 1 Optimal evolutionary paths under different parameter criteria (adapted from Traulsen et al, 2007). The starting state of the evolutionary process is A, and after a period of time it arrives at state B. The red line is the first path reached from A to B, i.e. the path that takes the shortest time, the blue line represents the path with the shortest distance between the two states, the green line denotes the path with the highest resource utilization during evolution, and the grey line shows the path of path-dependent selection in the process of evolution of the biological state.
