Like plants do: non-classical photosynthesis by earth’s inorganic semiconducting minerals

(Cactus Communications) Although much is known about biological photosynthesis, its evolutionary origin remains a mystery. In a recent study, scientists from Peking University, China, investigate the interaction between sunlight and minerals abundant on the Earth surface and propose novel mechanisms behind non-classical photosynthesis. Their work sheds light on the chemical history of our planet and suggests a way in which photosynthesis might have evolved from minerals.
