In this section a detailed description will be given of our current state of understanding of the phylogeny of the Metazoa. However, as explained in the introduction, the reader should realize that no fully resolved high-level metazoan phylogeny is yet available. As a result, the view of metazoan phylogeny presented here is a conservative estimate based on the synthesis of available molecular and morphological data. The metazoan phylogeny presented here does not represent the result of a single comprehensive phylogenetic analysis of all available evidence. Wherever it is relevant, congruence and conflict between data sources will be mentioned.
