- Low-wavelength geothermal light from acidic hydrothermal ventsIt is suggested that photosynthesis likely originated at low-wavelength geothermal light from acidic hydrothermal vents, Zn-tetrapyrroles were the first photochemically active pigments, the photosynthetic organisms were anaerobic and relied on H2S without relying on H 2 emitted by alkaline hydrothermal vents.
