Evolutionary biology seeks to understand the processes underlying the diversity of life on earth. All current diversity—whether among phyla, species or individuals—originated as mutations within populations. The fitness effects of new mutations and their rate of appearance are two of the most important quantities in evolution because they affect evolutionary rates, standing genetic variation and the advantage of other features such as the rate of inbreeding. The research proposed here will address fundamental questions concerning the causes and consequences of mutation in plant evolution.

进化生物学试图了解地球上生命多样性背后的过程。所有目前的多样性--无论是在门、种或个体之间--都起源于种群内的突变。新突变的适合度效应和它们的出现速度是进化中最重要的两个量，因为它们影响进化速度、持续的遗传变异和近亲交配等其他特征的优势。这里提出的研究将解决有关植物进化中突变的原因和后果的基本问题。
