Mitochondrial genomes have been a particularly fruitful data set for phylogenetic reconstructions. Due to their limited size and the availability of a large number of informative data sets, they are particularly interesting for the reconstruction of deep metazoan phylogeny. We aim to contribute to a well-supported phylogenetic tree of the metazoa by applying new evolutionary models and phylogenetic methods as well as by acquiring and analyzing new data. We propose to establish a refined model of mitochondrial genome evolution based on multiple genome rearrangements and correspondingly to develop efficient algorithms that are able to infer phylogenies from large data sets. The second major part of our project deals with analyzing metazoan mitochondrial genome sequences, aiming to resolve open questions concerning the phylogeny of the Metazoa.

线粒体基因组已经成为系统发育重建的一个特别富有成效的数据集。由于其有限的大小和大量的信息数据集的可用性，他们是特别感兴趣的深后生动物生殖系统的重建。我们的目标是通过应用新的进化模型和系统发育方法，以及通过获取和分析新的数据，有助于一个良好的支持后生动物的系统发育树。我们建议建立一个完善的模型，线粒体基因组进化的基础上多个基因组重排，并相应地开发有效的算法，能够推断从大数据集的遗传。我们的项目的第二个主要部分是分析后生动物的线粒体基因组序列，旨在解决有关后生动物生殖的开放性问题。
