Energy conversion of sunlight by photosynthetic organisms has changed Earth and life on it.
Photosynthesis arose early in Earth's history, and the earliest forms of photosynthetic life …

The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth
history. It allowed life to generate energy and reducing power directly from sunlight and …

Production of molecular oxygen was a turning point in the Earth's history. The geological
record indicates the Great Oxidation Event, which marked a permanent transition to an …

The evolution of oxygenic photosynthesis is a pivotal event in Earth's history because the O2
released fundamentally changed the planet's redox state and facilitated the emergence of …

Genome sequencing projects are revealing new information about the distribution and
evolution of photosynthesis and phototrophy. Although coverage of the five phyla containing …

Photosynthesis is the only significant solar energy storage process on Earth and is the
source of all of our food and most of our energy resources. An understanding of the origin …

Although biomarker, trace element, and isotopic evidence have been used to claim that
oxygenic photosynthesis evolved by 2.8 giga-annum before present (Ga) and perhaps as …

The evolution of oxygenic photosynthesis and ensuing oxygenation of Earth's atmosphere
represent a major transition in the history of life. Although many organisms retreated to …

Chlorophylls are magnesium-tetrapyrrole molecules that play essential roles in
photosynthesis. All chlorophylls have similar five-membered ring structures, with variations …
