跨越健身谷的进化速度
The pace of evolution across fitness valleys
摘要：
一个种群从一个适合度峰值进化到另一个适合度峰值的速度有多快？我们研究的动态演变，无性繁殖的人口中，一定数量的突变共同赋予健身优势。我们考虑的时间，直到人口已经从一个健身高峰发展到另一个更高的健身。突变的顺序可以是固定的或随机的。如果突变的顺序是固定的，那么种群会沿着一条比喻性的山脊，一条单一的路径进化;如果突变的顺序是任意的，那么有很多方法可以进化到更高的适应度状态。我们解决固定在这种情况下所需的时间，并研究它是如何受到突变的顺序，人口规模，健身值和突变率。
英文摘要：
How fast does a population evolve from one fitness peak to another? We study the dynamics of evolving, asexually reproducing populations in which a certain number of mutations jointly confer a fitness advantage. We consider the time until a population has evolved from one fitness peak to another one with a higher fitness. The order of mutations can either be fixed or random. If the order of mutations is fixed, then the population follows a metaphorical ridge, a single path. If the order of mutations is arbitrary, then there are many ways to evolve to the higher fitness state. We address the time required for fixation in such scenarios and study how it is affected by the order of mutations, the population size, the fitness values and the mutation rate.
