Blount wants to know if Fabich even read his papers

Lenski has issued a response through one of his co-researchers against what they call Ham's and Fabich's misrepresentations.

"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.)"
