The evolution of rod-dominant retinas was a critical adaptation, allowing mammalian ancestors to survive a nocturnal bottleneck. Kim et al. provide evidence suggesting that this evolutionary transition was driven by molecular innovations in the Maf-family protein NRL, which led to the recruitment of rods from S cones in early mammals.
