Early photosynthetic systems, such as those from green and purple sulfur and green and purple nonsulfur bacteria, are thought to have been anoxygenic, using various molecules as electron donors.
Fossils Of What Are Thought To Be Filamentous Photosynthetic Organisms Have Been Dated At 3.4 Billion Years Old, Consistent With Recent Studies Of Photosynthesis.
Web in a new article in heliyon, a researcher from imperial college london studied the molecular machines responsible for photosynthesis and found the process may. Early photosynthetic systems, such as those from green and purple sulfur and green and purple nonsulfur bacteria, are thought to have been anoxygenic, using various molecules as electron donors. Web they also found that the ancestors of cyanobacteria branched off from other bacteria around 3.4 billion years ago, with oxygenic photosynthesis likely evolving.

Ancient Microbes May Have Been Producing Oxygen Through Photosynthesis A Billion Years.
Web there is suggestive evidence that photosynthetic organisms were present approximately 3.2 to 3.5 billion years ago, in the form of stromatolites, layered. Web photosynthesis—both oxygenic and more ancient anoxygenic forms—has fueled the bulk of primary productivity on earth since it first evolved more than 3.4. Web previously, scientists believed that anoxygenic evolved long before oxygenic photosynthesis, and that the earth’s atmosphere contained no oxygen until about 2.4 to.
