New family FoxQD is broadly found in Metazoa but missing in Vertebrata and Porifera. The ML phylogenetic trees based on FKH of Q2 and QD family evolution in all metazoan species studied in this work. At nodes, values for the approximate Bayes (square) and Likelihood (circle) ratio test are shown. Colour indicates % of confidence. An Amq-J2/3 from the opposite clade was used as out group. Family branches are painted with the same colour as they are represented in the trees. Dark asterisk indicates a new fox characterized in Schmidtea mediterranea (Smed). Red cross indicates Saccoglossus kowalewski foxQD gene. Platyhelminthes QD genes are coloured light orange. Aminoacidic sequences used are placed in S1 and S3 File. Scale indicates expected aminoacidic substitution per site.
