Earth responded to its most severe past warming event by evolving a new and bizarre type of photosynthesis that allowed a group of primitive plants to survive. Research led by the University of Leeds has revealed how lycophytes—a type of ancient plant—not only survived a mass extinction 250 million years ago but then came to dominate the recovering landscapes.
