  "summary": "Photosymbiosis has evolved independently across multiple animal phyla, yet the cellular and evolutionary principles that repeatedly enabled animals to accommodate photosynthetic symbionts remain unclear. Here we show that the acoel Praesagittifera naikaiensis maintains intercellular photosymbiosis with the green alga Tetraselmis through a division of labour among conserved host cell populations…",
