标题： An Elementary Microscopic Model of Sympatric Speciation

摘要： 以达尔文雀为例作为叙述主题，引入了一个微观的基于代理的模型，用于研究同域物种形成，这是在同一生态位中资源竞争的结果。 在个体间竞争和资源分布变化的情况下，该模型表现出进化分支过程的一些主要特征。 该模型可以扩展以包括空间效应、不同的基因位点、有性交配和重组等。 显示英文摘要

摘要： Using as a narrative theme the example of Darwin's finches, a microscopic agent-based model is introduces to study sympatric speciation as a result of competition for resources in the same ecological niche. Varying competition among individuals and resource distribution, the model exhibits some of the main features of evolutionary branching processing. The model can be extended to include spatial effects, different genetic loci, sexual mating and recombination, etc.
