I want to know the answer to the following question:
What offshoots of polychaetes are unsegmented?
All the background I'm provided with is that "In addition to re-writing the classification of annelids and 3 previously independent phyla, the molecular phylogenetics analyses undermine the emphasis that decades of previous writings placed on the importance of segmentation in the classification of invertebrates.". Is that enough to answer the question?
Answer: no
