The evolutionary history of the occludin- and metallothionein-linked KRTAPs. Y-axis: the number of KRTAPs found by a BLAST search of the denoted animals, using as bait either occludin—O lineage (open circles) or a metallothionein—M lineage (filled circles). The time when the denoted clade or animal species first appeared is given on the X axis
