* Brls and σ values were multiplied with 10 for better readability. We used all sequences available for the Mollusca, Sipuncula and Kamptozoa with a length over 1,600 bp, supplemented by some other Lophotrochozoa and Priapulus caudatus.

Sequence composition of Mollusca within selected taxa measured using the disparity index (ID), compositional distance (CD), GC content [%], gene length in base pairs (bp) and average branch lengths (brls) and their standard deviation (σ). Brls and σ values were multiplied with 10 for better readability. We used all sequences available for the Mollusca, Sipuncula and Kamptozoa above 1,600 bp supplemented by several other Lophotrochozoa and Priapulus caudatus.
