Since we're talking about sex & evolution I thought I would pass on this PNAS paper, Coevolution of robustness, epistasis, and recombination favors asexual reproduction (my emphasis). I covered statistical epistasis a few years ago, and at that point I was being told that synergistic epistasis was the critical cog that kept the species a rollin' and a rockin'. But perhaps not (the paper is Open Access).
