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. Using two established methods for infering phylogenies as a starting point, namely multiple genome rearrangements as well as circular alignments, we propose to establish a refined model of mitochondrial genome evolution and correspondingly to develop efficient algorithms that are able to infer phylogenies from large data sets. A second major part of our project deals with acquiring and analyzing mitochondrial genome sequences, aiming to resolve open questions concerning the evolutionary roles and relationships between certain taxa such as Porifera, Placozoa, Cnidaria and Bilateria (including Hemichordata, Echinodermata and Chordata).
