On the other hand, many anaerobic microbes including methanogens are easily poisoned by oxygen, and the recent discovery of banded sediments with rusted iron on Akilia Island in West Greenland suggests that oxygen - producing, photosynthetic microbes (e.g., cyanobacteria) living on the surface of wet areas to gather sunlight may have developed by the end of this geologic period (3.85 billion years ago) despite continuing bombardment from space.

As proposed by Andrew Goldsworthy in 1987, cyanobacteria and later chloroplast - related protists and plants developed after microbes that used a purple pigment bacteriorhodopsin that absorbs green light dominated the oceans, and so the new photosynthetic cyanobacteria were forced to use the left - over light with chlorophyll that reflects green light, which was too complex to change even after purple - reflecting photosynthetic lifeforms were no longer dominant (Debora MacKenzie, New Scientist, September 10, 2010 — more on the evolution of photosynthetic life and plants on Earth).
