选择最适者作为物种形成机制
Choosing the fittest as a speciation mechanism
摘要：
当种群处于非均匀环境中时，性状的适应度值会随其在环境中的位置而变化。然而，随机交配引起的基因流动可以防止有性繁殖的种群在这种情况下分裂成不同的物种。这就是同域物种形成的问题。然而，交配不一定是完全随机的。在这里，我们提出了一个模型，其中个别有利的偏好合作伙伴的高适应度可以导致遗传聚类作为物种形成的先决条件。在模拟中，在适当的参数制度，我们的模型导致相应的等位基因的快速固定。
英文摘要：
When a population inhabits an inhomogeneous environment, the fitness value of traits can vary with the position in the environment. Gene flow caused by random mating can nevertheless prevent that a sexually reproducing population splits into different species under such circumstances. This is the problem of sympatric speciation. However, mating need not be entirely random. Here, we present a model where the individually advantageous preference for partners of high fitness can lead to genetic clustering as a precondition for speciation. In simulations, in appropriate parameter regimes, our model leads to the rapid fixation of the corresponding alleles.
