  1. Another possible explanation for unusual range of species

    You wrote, "the range of species in which mutation of the ARGFX locus is found do not form a monophyletic group to the exclusion of humans. There are several possible explanations for this unusual pattern." Then you list four possibilities.

    I think you omitted an important one, horizontal gene transfer. This also could account for the unusual distribution.

    Competing interests

    I have no competing interest, technically, but I actively advocate a competing theory, cosmic ancestry. In it, horizontal gene transfer is the dominant means of new gene acquisition.
