A simple stochastic model assuming continuous traits, normally distributed modifications, selection for fertility and multiplicative fitness was used to simulate phenotypic evolution by "reproducing individuals" in a given fitness landscape. Of particular interest was how small populations cross saddles separating distinct adaptive peaks. The simulated evolution exhibits a strong dualism: at the same level of reproductive errors, sexual reproduction provides significantly better local adaptation and asexual reproduction provides significantly better adaptive dynamics.
一个简单的随机模型被用于在给定的适应度景观中通过“繁殖个体”来模拟表型进化，该模型假设性状连续、修饰呈正态分布、对生育力进行选择且适应度具有相乘性。特别令人感兴趣的是小种群如何跨越分隔不同适应峰的鞍点。模拟进化呈现出强烈的二元性：在相同水平的繁殖误差下，有性繁殖提供显著更好的局部适应性，而无性繁殖提供显著更好的适应动态。
