The study group is taxa 1-4; taxon 5 is the outgroup for taxa 1-4 (remember that the outgroup is a reference group outside of the study group). The head has a pair antennae and ocelli. 6. In this exercise we will omit the small classes Symphyla and Pauropoda, and focus on the centipedes, millipedes, and insects, beginning with the least specialized tracheates, the Chilopoda.
