DISSERTATION RESEARCH Modeling ornament preference

项目摘要

Some of the most spectacular traits in nature are ornaments used by members of one sex in competition for access to mates or fertilization opportunities. Of particular interest is the process by which mating preferences and sexually-selected ornaments evolve in tandem. There are many models describing the various conditions determining how these traits evolve together, but all of them rest on assumptions that have never been theoretically tested. The genes controlling the ornament and genes controlling the mating preference have always been assumed to be inherited in a manner that maintains a constant genetic architecture. The goal of this study is to explore the dynamics of ornament-preference joint evolution when the genetic architecture itself is allowed to evolve. Individual-based simulation models will be used to explore regions of parameter space that facilitate or hinder the rapid evolution of mating preferences and ornaments predicted by long-standing theory. The results of this project will provide a better understanding of the evolution of genetically correlated traits in general. Moreover, the simulation models will be useful for the demonstration of evolutionary processes to students and will help to communicate to the public how computer models can be used to dissect complex natural processes.

自然界中一些最引人注目的特征是一种性别的成员在争夺配偶或受精机会时使用的装饰品。特别令人感兴趣的是交配偏好和性选择装饰物的协同进化过程。有许多模型描述了决定这些特征如何共同进化的各种条件，但所有这些模型都基于从未经过理论验证的假设。控制装饰的基因和控制交配偏好的基因一直被认为是以保持恒定遗传结构的方式遗传的。本研究的目的是探索当遗传结构本身允许进化时，顺从偏好联合进化的动力学。基于个体的模拟模型将用于探索参数空间的区域，这些区域促进或阻碍长期理论预测的交配偏好和装饰的快速进化。这个项目的结果将提供一个更好的理解一般遗传相关性状的进化。此外，模拟模型对于向学生演示进化过程非常有用，并将有助于向公众传达如何使用计算机模型来剖析复杂的自然过程。
