摘要

An essential aspect of the current theory of adaptive speciation is the maintenance of phenotypic variation and the 演化 of stationary stable phenotypic 多樣性, a phenomenon known as 演化ary branching. Theoretical and empirical evidence suggest that phenotypic variation can be maintained by favoring rare phenotypes, for example, through frequency-dependent selection. However, even when phenotypic variation is provided, the conditions leading to 演化ary branching are not universal. In order to lead to stable diversification, current models of adaptive speciation, such as the Lotka-Volterra competition model, must resort to strong assumptions that range from using unrealistic shape parameters for the competition and carrying capacity functions, modeling separately the generation of discontinuities in
