  • SUMMARY Research into arthropod evolution is hampered by the derived nature and rapid evolution of the best‐studied out‐group: the nematodes. We consider priapulids as an alternative out‐group. Priapulids are a small phylum of bottom‐dwelling marine worms; their tubular body with spiny proboscis or introvert has changed little over 520 million years and recognizable priapulids are common among exceptionally preserved Cambrian fossils. Using the complete mitochondrial genome and 42 nuclear genes… CONTINUE READING
