梅纳德·史密斯(Maynard Smith)和萨特玛丽(Szathmary)提出了一个问题,即在有限的杂交中,证明连续的性类型的不稳定性。在这里,我提出了一个模型,其中可以分析究竟何时以及如何存在的不稳定性可以依赖于一个Allee效应,以及如何的增长率和典型规模的不稳定扰动取决于竞争的强度和范围,交配偏好,生育力和后代的方差由于孟德尔分离和突变。各种不稳定性发生在大多数参数制度。简而言之,这个连续体经常分裂成初始物种。
Maynard Smith and Szathmary have posed the problem of demonstrating the conjectured instability of a continuum of sexual types with finite interbreeding. Here, I propose a model in which one can analyse exactly when and how the existence of the instability can depend on an Allee effect, and how the growth rate and typical scale of the unstable perturbations depend on the strength and range of competition, mating preference, fecundity and offspring variance due to Mendelian segregation and mutation. Instabilities of various kinds are shown to occur in the majority of parameter regimes. In short, the continuum often breaks up into incipient species.
