I have re-examined my 1970 article 'Evolution of Photosynthesis'(Olson JM, Science 168:
438–446) to see whether any of my original proposals still survive. My original conviction …

Photosynthesis is an ancient process on Earth. Chemical evidence and recent fossil finds
indicate that cyanobacteria existed 2.5–2.6 billion years (Ga) ago, and these were certainly …

The presence of shared conserved insertions or deletions in proteins (referred to as
signature sequences) provides a powerful means to deduce the evolutionary relationships …

If the endosymbiotic theory is correct, we should expect to see similarities between
chloroplasts and photosynthetic bacteria. Comparison of certain protein and nucleic acid …

Photosynthesis is a complex metabolic process that originated on the early Earth. Recently
reported evidence based on the molecular evolutionary analysis of the chlorophyll …

The origin and evolution of photosynthesis is considered to be the key to the origin of life.
This eliminates the need for a soup as the synthesis of the bioorganics are to come from the …

The prototype reaction center may have used protoporphyrin-IX associated with small
peptides to transfer electrons or protons across the primitive cell membrane. The precursor …

Abstract In 1893, Charles Barnes (1858–1910) proposed that the biological process for
'synthesis of complex carbon compounds out of carbonic acid, in the presence of …

Publisher Summary This chapter discusses the significance of evolutionary concepts in
understanding the photosynthetic machinery as it operates at present. Although hardly …

The origin and evolution of photosynthesis have long remained enigmatic due to a lack of
sequence information of photosynthesis genes across the entire photosynthetic domain. To …
