Photosynthesis: what color was its origin?
Open accessAbstract
Recent studies using geological and molecular phylogenetic evidence suggest several alternative evolutionary scenarios for the origin of photosynthesis. The earliest photosynthetic group is variously thought to be heliobacteria, proteobacteria or a precursor of cyanobacteria, organisms whose photosynthetic pigments make them different colors.

Molecular phylogenetic analysis of many enzymes involved in (bacterio)-chlorophyll biosynthesis suggests that anoxygenic photosynthetic lineages are likely more deeply rooted than oxygenic cyanobacterial lineages.
“Supporting this, molecular phylogenetic analysis of many enzymes involved in (bacterio)-chlorophyll biosynthesis suggests that anoxygenic photosynthetic lineages are likely more deeply rooted than oxygenic cyanobacterial lineages (Xiong, 2006).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
