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.

这项行动为2009财政年度的NSF博士后研究奖学金提供资金，并支持Rachel S的研究和培训计划，该计划题为“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”。史瓦兹这项研究的主办机构是雷切尔·穆勒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，因为关系最密切的物种通常差异最少。有些基因比其他基因更有助于评估这种关系。例如，有些基因进化得如此之慢，以至于它们在整个近亲物种群体中是相同的;另一些基因进化得如此之快，以至于它们在远亲物种中是如此不同，我们无法确定谁是最近亲的。同样，有些基因很短，它们不包含足够的信息来识别密切的关系。这项研究通过模拟遗传数据来确定基因的特征，从而确定有助于确定物种之间进化关系的基因。科学培训目标包括获得遗传学，生物信息学和计算方法的专业知识。本专业的培养目标是从种群到物种的进化研究，培养学生的指导和教学能力，为正确判断众多物种的进化关系做出贡献。
