我们研究了一个种群遗传模型与时间波动的适应度景观。我们的数值计算表明，一个反直觉的行为发生在系统的进化速度降低选择压力从零增加。这种现象可以通过与颗粒流中的绝对负迁移率类比来理解。并对演化方向作了唯象解释。
We investigate a population-genetic model with a temporally-fluctuating sawtooth fitness landscape. We numerically show that a counter-intuitive behavior occurs where the rate of evolution of the system decreases as selection pressure increases from zero. This phenomenon is understood by analogy with absolute negative mobility in particle flow. A phenomenological explanation about the direction of evolution is also provided.
