Comments P.183 3rd paragraph: "High protein-sequence conservation exists among the FF [fusion failure]-coding genes of other Caenorhabditis species that diverged from C. elegans 80–100 million years ago, including Caenorhabditis briggsae and Caenorhabditis remanei (primary sources del Campo, 2005, Sapir et al., 2007). Orthologs have also been identified in other nematode genera including Pristionchus pacificus, Trichinella spiralis, which diverged from C. elegans more than 200 and 600 million years ago, respectively (primary source Sapir et al., 2008). However, no FF homologs have been verified in creatures outside of the phylum nematoda."
