"...Note that this explanation requires no selection. It's just something that
happens, but it happens because there is no selection on the loci in question."

Paul is right on target.  This effect is known as "Muller's ratchet" ...
multiple mutations on a locus free of selection tend to progressively destroy
the function of its product.  Leslie and Vrijenhoek, Evolution
1988(??) demonstrated the effect.
