As we approach a vote on the UK's membership of the European Union, we look at what 50 writers, actors, historians, artists and comedians have said about Europe and its nations.
Several hypotheses exist about the phylogenetic relationships of Dictyoptera or its suborders [16–20,23,25–39].
This objective is classically achieved through analyses combining morphological and environmental data, molecular phylogenies, and the fossil record [1–3].
These analyses are, however, sometimes inconclusive, especially when the fossil record is disputed, scarce or incomplete (a limitation inherent to fossils) or when molecular phylogenies rely on limited samples [4–6].
Special attention must therefore be paid to improve character and taxon sampling in phylogenies and to evaluate the quality of the fossil record [7,8].
Despite these recommendations, obtaining additional data may be difficult even with a strong sampling effort, especially for fossils for which complete specimens in good state of preservation and phylogenetically relevant are not easily found.
We find the following topology: (mantises, (other cockroaches, (Cryptocercidae, termites)).
