通过健康和稳定的生存人口老龄化
Population aging through survival of the fit and stable
摘要：
受到广泛的已知自我复制系统的启发，其中一些远离遗传学，我们研究了一个由具有内部动态的个体组成的系统，该系统具有许多可能的部分稳定状态，具有不同的突变率。个体的繁殖和死亡率是每个状态的属性，不一定与其稳定性相关，后代出生在父母的状态。总种群受到资源或空间的限制，例如在恒化器或培养皿中。我们的目的是表明，突变率和健身变得更加相关，\emph{even if they are completely uncorrelated for an isolated individual}，强调这样一个事实，即由资源限制引起的相互作用本身是有效的产生集体效应。
英文摘要：
Motivated by the wide range of known self-replicating systems, some far from genetics, we study a system composed by individuals having an internal dynamics with many possible states that are partially stable, with varying mutation rates. Individuals reproduce and die with a rate that is a property of each state, not necessarily related to its stability, and the offspring is born on the parent's state. The total population is limited by resources or space, as for example in a chemostat or a Petri dish. Our aim is to show that mutation rate and fitness become more correlated, \emph{even if they are completely uncorrelated for an isolated individual}, underlining the fact that the interaction induced by limitation of resources is by itself efficient for generating collective effects.
