How do species adapt to different climatic regimes? What are the genes involved, and what are the mechanisms that operate at the molecular level to confer a match between an organism's traits and its environment? What genetic properties induce incompatible reproduction between groups of individuals to create and maintain distinct species? How general are common "rules" of such speciation, and what genetic properties underlie their evolution? These are some of the fundamental questions about the origins of biodiversity that this research seeks to answer.

物种如何适应不同的气候条件？有哪些基因参与其中，又有哪些机制在分子水平上使有机体的特征与其环境相匹配？什么遗传特性导致个体群体之间的不相容繁殖以创造和维持不同的物种？这些物种形成的共同“规则”有多普遍？它们的进化背后有哪些遗传特性？这些都是本研究试图回答的关于生物多样性起源的一些基本问题。
