That is the truth. Purely natural processes are actually capable of producing high FI in that antibodies are evolved in only two weeks.
Both you and gpuccio have tried to pretend that only one process (somatic hypermutation) is producing FI, while ignoring V(D)J recombination.
Didn’t @gpuccio claim that he was going to do an analysis of antibody evolution? Whatever happened to that, Gil? Did he not get the answer he was hoping for?
