Summary

[edit]
Description

Simplified representation of the trees obtained in three recent phylogenomic analyses of early animal diversification.

(A) Schierwater et al. [4] tree. (B) Dunn et al. [2] tree. (C) Philippe et al. [3] tree. Numbers in parentheses after taxon names indicate the number of species included in the dataset for the corresponding taxon. Bootstrap support values above 90% are indicated by a bullet (for nodes) or by underlining (for terminal taxa). It is worth mentioning that the monophyly of Porifera is not unequivocally accepted [28],[46]; only the analysis of 30,000 positions with a rich taxon sampling and a complex model of evolution recovers it with significant statistical support [3]. Although such a sparse phylogenetic signal will require harnessing the full potential of phylogenomics to be confidently solved, this question is outside the scope of this study. Simplified drawings (redrawn from [74]) on the bottom illustrate the huge morphological disparity existing between the five terminal taxa. Porifera correspond to sponges; Cnidaria to sea anemones, jellyfishes, and allies; Ctenophora to comb jellies; and Bilateria to all other animals (characterized by their bilateral symmetry) except Trichoplax (Placozoa), which appears to be morphologically the most simply organized animal phylum.
