Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very close to the origin of life on earth. In a new article in Heliyon, a researcher from Imperial College London studied the molecular machines responsible for photosynthesis and found the process may have evolved as long as 3.6 billion years ago.
The author of the study, Dr. Tanai Cardona, says the research can help to solve the controversy around when organisms started producing oxygen -- something that was vital to the evolution of life on earth. It also suggests that the microorganisms we previously believed to be the first to produce oxygen -- cyanobacteria -- evolved later, and that simpler bacteria produced oxygen first.
