Moving to the Light: The Evolution of Photosynthesis,ryotes. Major similarities in the molecular architecture of photosystems in extant bacterial lineages point to a monophyletic origin of the core photosynthetic machine, followed by horizontal transfer among distantly related taxa, duplication and neo-functionalization. The Archaea lack photosynthesi

The Great Oxygenation Event,but the causal link between the two events is uncertain. Oxygen atmospheric concentration stabilized at a low level during most of the Proterozoic. A second rise in oxygen concentration, probably reflecting an increase in global productivity and organic carbon sequestration, started around 800 MYA.

The Animals, Thus, the intestine was a fundamental innovation that paved the way to the evolution of most other animal traits. The diffusion of animals in Cambrian oceans enhanced organic carbon sequestration at the ocean bottom due to the sinking of carcasses and faeces, thus probably contributing to coeval ri
