  • Evolution of photosynthesis - Wikipedia
    The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen rather than water [2] There are three major metabolic pathways by which photosynthesis is carried out: C 3 photosynthesis , C 4 photosynthesis , and CAM photosynthesis
  • Early Evolution of Photosynthesis - PMC - PubMed Central (PMC)
    Current evidence suggests that the earliest photosynthetic organisms were anoxygenic, that all photosynthetic RCs have been derived from a single source, and that antenna systems and carbon fixation pathways have been invented multiple times
  • Timeline of Photosynthesis on Earth | Scientific American
    These ubiquitous bacteria were the first oxygen producers They absorb visible light using a mix of pigments: phyco­bilins, carotenoids and several forms of chlorophyll These organisms have
  • Scientists Uncover the Earliest Fossil Evidence of Photosynthesis
    Cyanobacteria, or blue-green algae, on the surface of a lake Bacteria were the first organisms to photosynthesize, creating the oxygen essential for the evolution of life on Earth
  • Photosynthesis more ancient than thought, and most living things could . . .
    But the new research reveals that a more ancient bacteria, that probably no longer exists today, was actually the first to evolve the simpler form of photosynthesis, and that this bacteria was an ancestor to most bacteria alive today
  • AP Biology 3. 5 - Photosynthesis - AP Biology | Biology Dictionary
    Photosynthesis first evolved in prokaryotic organisms Scientific evidence supports the claim that prokaryotic (cyanobacterial) photosynthesis was responsible for the production of an oxygenated atmosphere
  • Scientists discover how life on Earth began 1. 75 billion years ago
    Photosynthesis, in its earliest form, likely emerged around 3 5 billion years ago as anoxygenic photosynthesis, a process that did not produce oxygen Cyanobacteria were among the first organisms to transition to oxygenic photosynthesis, using specialized cell structures called thylakoid membranes
  • Early Evolution of Photosynthesis | Plant Physiology - Oxford Academic
    Photosynthetic phyla include the cyanobacteria, proteobacteria (purple bacteria), green sulfur bacteria (GSB), firmicutes (heliobacteria), filamentous anoxygenic phototrophs (FAPs, also often called the green nonsulfur bacteria), and acidobacteria (Raymond, 2008)
  • The Evolution of Photosynthesis in Prokaryotes and Eukaryotes
    The emergence of photoautotrophic prokaryotes marks a significant chapter in the history of life on Earth These organisms, primarily cyanobacteria, are believed to have been among the first to perform oxygenic photosynthesis, which involves converting light energy into chemical energy with the release of oxygen
  • Origin and evolution of photosynthesis - ScienceDirect
    The first photosynthetic organisms must have evolved to use the biosynthetic pathway for F 430, and to add new synthetic enzymes to synthesize Chl and BChl homologs Modern hydrogen-using methanogens are classified as Archaea, and many Archaea are found near deep-sea hydrothermal vents
