This strikes me as a decent example of a phenomenon one often finds: People not quite grasping a scientific term or its significance and then inventing (absurd) arguments based on that misunderstanding. In this case, “living fossil.” (Which are interesting, and do raise some interesting questions - but definitely not the one above!)
An old teacher of mine compared it to a town fool who explains his having the flu as resulting from his DNA getting twisted into knots. He’s working with real concepts - DNA, DNA-folding, the flue - but just not making any sense at all.
