DEB-0075605Heather M. WilsonDrs. Heather M. Wilson, Jerome C. Regier and Jeffrey W. Schultz of the University of Maryland have been awarded a grant to study the evolution of millipedes (Class Diplopoda). The millipedes are one of the most diverse groups of animals, with more than 8,000 species. They are important components of terrestrial ecosystems and appear to have been so for over 400 million years. Nonetheless, the role of millipedes in the life history of our planet is not well understood. The project detailed here will resolve the evolutionary relationships (phylogeny) of the millipede orders through extensive original analyses of muscular anatomy, fossil morphology and DNA sequences. This project has four main objectives: (1) to survey the skeletal muscles; (2) to examine the skeletal anatomy of fossilized species; (3) to comparatively sequence the DNA coding for three nuclear protein-encoding genes (elongation factor-1a, RNA polymerase II and elongation factor-2); (4) to use these data, separately and in combination, to infer the phylogeny (family tree) of millipedes and their relatives. This work is unusually interdisciplinary in that it represents a collaboration of specialists in paleontology, comparative anatomy and molecular genetics. This integrative approach to millipede phylogeny promises substantial insights into the evolutionary biology of a large, important group of organisms and will produce and permit the integration and analysis of data of three very different types to address a single question.

Schultz获得了一项研究基金，用于研究千足虫（双足纲）的进化。千足虫是最多样化的动物群体之一，有8000多种。它们是陆地生态系统的重要组成部分，似乎已经存在了4亿多年。尽管如此，千足虫在地球生命史上的作用还没有被很好地理解。这里详细介绍的项目将通过对肌肉解剖、化石形态和DNA序列的广泛原始分析来解决千足虫目的进化关系（系统发育）。该项目有四个主要目标：(1)调查骨骼肌；(2)检查化石物种的骨骼解剖；(3)对三个核蛋白编码基因（延伸因子-1a、RNA聚合酶II和延伸因子-2）的DNA编码进行比较测序；(4)分别或结合使用这些数据来推断千足虫及其近亲的系统发育（家谱）。这项工作是不同寻常的跨学科，因为它代表了古生物学、比较解剖学和分子遗传学专家的合作。这种研究千足虫系统发育的综合方法有望对大型重要生物群体的进化生物学产生实质性的见解，并将产生并允许对三种非常不同类型的数据进行整合和分析，以解决一个问题。
