Sure, but how "common" is H2S as opposed to water? From what I've read
of the archaea and other tectonic dwellers, the H2S they live off of is
produced by water seeping down through fissures, coming in contact with
hot sulfur rich rock, which creates H2S. Thus even in the most remote
areas that life has evolved that we know of, such chemistry is dependent
on water, at least indirectly.
How common is H2S in space or on other planets in our solar system? I
think there is some on Saturn's moon Titan, as well as all sorts of
hydrocarbons. The gist of my argument is that life will evolve with what
ever chemistry is commonly available and most efficient. How does H2S
rate compared to H2O as a solvent? Like my previous statement comparing
silicon and carbon, what is more useful? Also, what is the temperature
range that is most conducive toward H2S based chemistry? or other common
natural solvents for that matter?
