That's why I said near-equilibrium, precisely because I read about the E. Coli experiment on http://www.npr.org/blogs/health/2013/11/15/245168252/bacterial-competition-in-lab-shows-evolution-never-stops http://www.npr.org/blogs/health/2013/11/15/245168252/bacteri... and I trusted the editor where it says "The pace of improvement is slowing down, but shows no sign of stopping". Perhaps I shouldn't had to say "evolution", but "improvement" instead, which is much more accurate.
