This project aims to determine whether evolution is primarily unpredictable and stochastic, or predictable and constrained along certain pathways. By using a natural experiment that caused wood-feeding cockroaches to evolve into soil-burrowing cockroaches in response to climate change millions of years ago, this project will determine how the genomes of these organisms responded. This will show whether the same molecular changes are repeatedly used in the evolution of complex traits, including burrow construction. This will contribute to the understanding of how predictable evolution is at the molecular level, and provide insights into how genomes change in response to prolonged climate change.

这个项目的目的是确定进化是否主要是不可预测和随机的，或者沿着沿着某些路径是可预测和受约束的。通过使用一个自然实验，导致食木蟑螂进化成土壤穴居蟑螂，以应对数百万年前的气候变化，该项目将确定这些生物的基因组如何反应。这将显示相同的分子变化是否重复用于复杂性状的进化，包括洞穴建设。这将有助于理解在分子水平上如何预测进化，并提供对基因组如何响应长期气候变化的见解。
