Debate about Cambrian lophotrochozoans
Since 1990 there has been intense debate among paleontologists about the evolution in the Early Cambrian period of the ""super-phylum"" Lophotrochozoa, which is thought to include the modern molluscs, annelid worms and brachiopods, as well as their evolutionary ""aunts"" and ""cousins"".
