The Priority Programme combines resources and expertise to clarify important aspects of the phylogeny of large metazoan taxa and to infer processes of molecular evolution and of the historical evolution of phenotypes. In focus are the phylogenetic relationships between animal taxa traditionally classified as phyla . Past publications based on morphological or molecular data or combining both are extremely inconsistent, partly because data quality was not evaluated, partly because processes of evolution are not well understood. The Ecdysozoa hypothesis, for example, combines nematods and arthropods in a single clade, contradicting the Articulata , a clade composed of annelids and arthropods. The first is mainly supported by molecular data of unpublished signal to noise ratio, the second is based on morphological observations. The contradictions are currently unsettling biologists whose research depends on correct phylogenies, teachers, authors of textbooks.

优先规划结合资源和专业知识，阐明大型后生动物类群系统发育的重要方面，并推断分子进化过程和表型的历史进化。重点是传统分类为门的动物类群之间的系统发育关系。过去基于形态学或分子数据或两者结合的出版物极不一致，部分原因是数据质量没有得到评估，部分原因是进化过程没有得到很好的理解。例如，外生动物假说将线虫和节肢动物结合在一个分支中，与节肢动物和环节动物组成的分支关节动物相矛盾。前者主要由未发表的分子信噪比数据支持，后者主要基于形态学观察。目前，这种矛盾让依赖正确系统发生学来进行研究的生物学家、教师和教科书作者感到不安。
