is the video link. Watch Ham's pet . Note the link to a by Lenski and his grad student where they themselves call Fabitch out.
The second argument was more direct. Both Ham and Fabich asserted that the Cit+ function did not evolve because using citrate did not involve “any kind of new information … it’s just a switch that gets turned on and off.” (Fabich went on to state that this “switch” is what we reported. That is emphatically not true. It beggars belief that anyone, much less a trained microbiologist, could actually read our 2012 paper, where we reported the genetic basis of Cit+, and come away thinking this.) Variations on that wording are often used by creationists who discuss the citrate work because it implies that Cit+ arose because of a pre-existing regulatory switch and involved no evolution at all. But that simply is not the case – that wording, dare I say it, is a lie.
