The molluscs are one of the most diverse and abundant groups of animals in the world today. An understanding of the manner in which this group has diversified in form and habitat is hampered by the lack of information concerning the precise relationships and ancestry among the molluscan classes. The positions of the thirty- seven genes around the circular mitochondrial DNA molecule will be determined from representatives of the classes of molluscs and other animals believed to be related to molluscs on the basis of anatomical characters. These positions will be determined by DNA sequencing of selected regions of the mitochondrial molecule for each of the animals in the study. This data will be combined with DNA nucleotide sequencing of selected regions of the mitochondrial molecule for each of the animals in the study. This data will be combined with DNA nucleotide sequence data from several of the conserved protein-coding mitochondrial genes in order to understand precisely how these animals are related. This approach, using data from two different molecular levels, is appropriate when studying truly ancient radiations of animals. The results of this study will form the basis for the first clear analysis of trends in the form, diversity, and ecology of the molluscs.

软体动物是最多样化和丰富的群体之一， 当今世界的动物 理解的方式， 这个群体在形式和栖息地上的多样性受到阻碍 由于缺乏关于确切关系的信息， 是软体动物的祖先 三十人的位置- 围绕环形线粒体DNA分子的七个基因将被 根据软体动物类的代表确定， 其他被认为与软体动物有关的动物， 解剖特征 这些位置将由DNA决定 对线粒体分子的选定区域进行测序， 研究中的每只动物。 这些数据将与 线粒体DNA选择区域的核苷酸测序 研究中的每只动物的分子。 这些数据将 结合来自几个国家的DNA核苷酸序列数据 保守的蛋白质编码线粒体基因，以了解 这些动物之间的关系 这种方法使用数据 从两个不同的分子水平， 真正古老的动物辐射。 本研究结果 将构成第一次明确分析2010 - 2011年趋势的基础。 软体动物的形态、多样性和生态学。
