在人类和许多其他物种中，死亡率集中在生命周期的早期，在扩散和繁殖阶段死亡率较低。然而，移民和遗传漂变的经典群体遗传学模型所假设的恰恰相反。我们引入了一个模型，在该模型中，人口调节发生在迁移之前。与传统模型相反，我们的模型意味着新生儿等位基因频率的地理变异应该超过成人。因此，重要的是要区分具有类似人类生命周期的物种中成年人和新生儿的遗传变异。
In humans and many other species, mortality is concentrated early in the life cycle, and is low during the ages of dispersal and reproduction. Yet precisely the opposite is assumed by classical population‐genetics models of migration and genetic drift. We introduce a model in which population regulation occurs before migration. In contrast to the conventional model, our model implies that geographic variation in the allele frequencies of newborns should exceed that of adults. Thus, it is important to distinguish genetic variation of adults from that of newborns in species with human‐like life cycles.
