Evolution of the Warthog family. a Schematic detailing the duplication history of the Warthogs in the nematodes. Degenerate Wrts are represented by a dashed line. The three degenerate ‘wrt-4’ paralogues present in P. pacificus are not shown for clarity. b Cladogram showing the evolutionary relationships between the ten Warthogs and their functions according to the results of this investigation. wrt-7 (grey) is a pseudogene with no obvious functionality
