Photosynthesis, the process by which plants and other organisms convert sunlight into chemical energy, has been a major player during the evolution of life and our planet s atmosphere. Although most of the ins and outs of photosynthesis are understood, how the necessary mechanisms evolved is still a topic of debate. The answer to this question, however, may actually lie buried in the mineral world.
In a recent study published in Earth Science Frontiers (10.13745/j.esf.sf.2020.12.3), scientists from Peking University, China, shifted the focus in photosynthesis research from plants and bacteria one step further back to rocks and substances found in what s known as the mineral membrane of Earth. They propose that various components of this relatively thin layer, such as bir ....
