论文摘要
进化中的一个关键问题是突变体有多大可能接管。这取决于自然选择和随机波动。人口空间结构会影响突变固定概率。我们在图表上引入了一个结构化人群的模型，该模型通过将迁移独立于生死而概括为概括。我们证明，通过调整迁移不对称，恒星图从放大到抑制自然选择。我们的模型的结果是普遍的，因为它们不在微观动态或更新规则的建模选择上取决于它们。取而代之的是，它们取决于迁移不对称，可以通过实验调整和测量。
A key question in evolution is how likely a mutant is to take over. This depends on natural selection and on stochastic fluctuations. Population spatial structure can impact mutant fixation probabilities. We introduce a model for structured populations on graphs that generalizes previous ones by making migrations independent of birth and death. We demonstrate that by tuning migration asymmetry, the star graph transitions from amplifying to suppressing natural selection. The results from our model are universal in the sense that they do not hinge on a modeling choice of microscopic dynamics or update rules. Instead, they depend on migration asymmetry, which can be experimentally tuned and measured.
