This action funds an NSF Postdoctoral Research Fellowship for FY 2009 and supports a research and training plan entitled "Developing a model to guide selection of genes to determine evolutionary relationships among species" for Rachel S. Schwartz. The host institution for this research is Colorado State University under the sponsorship of Rachel Mueller.The evolutionary relationships among species are an important basis for research in biology. One way to determine such relationships is by examining differences in a gene within a group of species as species that are most closely related generally have the fewest differences. Some genes are more useful than others for estimating such relationships. For example, some genes evolve so slowly that they are identical for whole groups of closely related species; other genes evolve so quickly that they are so different for distantly related species we cannot determine who is most closely related. Similarly, some genes are so short that they do not contain enough information to identify close relationships. This research is identifying genes that will be useful for determining evolutionary relationships among species by simulating genetic data to determine the characteristics of genes that will be useful for this purpose. Scientific training objectives include gaining expertise in phylogenetics, bioinformatics, and computational methods. Professional training objectives include developing a research program spanning evolution from the population to the species level and developing skills in mentoring and teaching students.This research will contribute to correctly determining evolutionary relationships of numerous species.

这项行动资助了 2009 财年 NSF 博士后研究奖学金，并支持 Rachel S. Schwartz 题为“开发一个模型来指导基因选择以确定物种之间的进化关系”的研究和培训计划。这项研究的主办机构是Rachel Mueller赞助的科罗拉多州立大学。物种之间的进化关系是生物学研究的重要基础。确定这种关系的一种方法是检查一组物种内基因的差异，因为相关性最密切的物种通常差异最小。对于估计这种关系，一些基因比其他基因更有用。例如，有些基因进化得非常缓慢，以至于对于整个密切相关的物种群体而言，它们都是相同的；其他基因进化得如此之快，以至于它们对于关系较远的物种来说是如此不同，我们无法确定谁的关系最密切。同样，有些基因非常短，以至于它们不包含足够的信息来识别密切关系。这项研究正在通过模拟遗传数据来确定有助于确定物种之间进化关系的基因，以确定有助于此目的的基因的特征。科学培训目标包括获得系统发育学、生物信息学和计算方法方面的专业知识。专业培训目标包括制定涵盖从种群到物种层面进化的研究计划，以及培养指导和教学学生的技能。这项研究将有助于正确确定众多物种的进化关系。
