运动、注视概率与进化过程的选择

Motion, fixation probability and the choice of an evolutionary process

Francisco Herrerías-Azcué, Vicente Pérez-Muñuzuri, Tobias Galla

摘要:

已知不同的进化模型在某些情况下会对入侵突变体的成功做出完全不同的预测。例如,一些进化机制会导致结构化种群中选择的放大,而另一些则会抑制它。在这里,我们使用计算机模拟来研究由流动移动的进化种群,并展示这种运动的速度如何影响入侵突变体的固定概率。不同速度的流在固定的异质图上的演化动力学和在充分搅拌的种群之间插值。我们发现,运动有一个积极的作用,在放大或抑制选择,完成碎片化和重新连接的相互作用图。虽然增加流速抑制大多数进化模型的选择,我们确定的特征响应流不同的更新规则,我们测试。我们建议这些反应作为一个潜在的援助,为给定的生物系统选择最合适的更新规则。

英文摘要:

Different evolutionary models are known to make disparate predictions for the success of an invading mutant in some situations. For example, some evolutionary mechanics lead to amplification of selection in structured populations, while others suppress it. Here, we use computer simulations to study evolutionary populations moved by flows, and show how the speed of this motion impacts the fixation probability of an invading mutant. Flows of different speeds interpolate between evolutionary dynamics on fixed heterogeneous graphs and in well-stirred populations. We find that the motion has an active role in amplifying or suppressing selection, accomplished by fragmenting and reconnecting the interaction graph. While increasing flow speeds suppress selection for most evolutionary models, we identify characteristic responses to flow for the different update rules we test. We suggest these responses as a potential aid for choosing the most suitable update rule for a given biological system.
