Scientists are now studying those organisms for insights into the early evolution of photosynthesis.Arctic-Images/Getty Images The latest important clue comes from Heliobacterium modesticaldum, which ...

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.

Nearly three-fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth's oceans were once green, in ...

CAMBRIDGE, MA -- During photosynthesis, an enzyme called rubisco catalyzes a key reaction — the incorporation of carbon dioxide into organic compounds to create sugars. However, rubisco, which is ...
