I want to know the answer to the following question:
In addition to Carboniferous, what other insect order is inclusive of extant groups, stem groups and Paleozoic groups?
All the background I'm provided with is that "Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct.". Is that enough to answer the question?
Answer: yes
