Reference 18 is this one:
We had several threads on this forum devoted to explaining the damage control and panic-spawned lies output by the Discovery Institute in response to that paper, since it so directly refuted so many of their claims. It’s also, incidentally, a demonstration of what @colewed claimed in the other thread is just speculation: the real-time evolution of a gene with a novel function through duplication and divergence.
I remember those threads well because I had to go into the methods of the papers and explain to Ann Gauger how she got several simple facts about those experiments completely wrong. Funny.
