During evolution, genes can be recruited to new positions to perform novel functions. This study shows one such co-option event, where the reused gene networks are initially interlocked, so that any changes because of their function in one organ are mirrored in the other organs even if they provide no selective advantage, opening the potential for acquiring a novel function.
