Figure 4

Neighbournet graph of the data used in Fig. 3. In this graph a split is defined by asset of parallel edges. Edge length is proportional to the weight of the associated split [30]. The strongest split separates the outgroups from Branchiopoda, and within Branchiopoda the best splits support Anomopoda, Cladocera and Anostraca. For part of the data (small subnet to the left) there is little signal. These differences in clade support are not seen in Fig. 3.
