I have and am currently measuring discrete photosynthetic radiation in the
blue and red using miniature data loggers under a wide variety of natural
conditions in Texas, Hawaii and Brazil. Can you please give me a citation
for your statement that "the first type of photosynthesis to evolve did
not produce oxygen." 

Thank you.
