Re: Is there any non-chlorophyl/non-cyanobacteria photosynthesis?



But, Bill's point is right -- seems like phototrophs would be much happier
near the surface, no? Something to do with UV damage?

What exactly is that damage - besides pyrimidine dimers?

Mars has a thin atmosphere, yet no one talks about UV damage.
Earth with all its thick atmosphere gets one photon and the sea is
sterilized!

IF UV is really that damaging to the origin, what exactly is destroyed
and how?
(see my D. Darling entry on UV at end of encyclopedia article LIfe,
origin of.)
