The formation of the continuous digestive tract was a key feature during bilaterian evolution, but how the function of the early through-gut is regulated is not well known. Here they uncover light-modulated neural control of sphincters in sea urchin larvae, providing insights into the evolution of through-gut regulation in ancient bilaterians.
