The great quest for life elsewhere in the universe is for ANY type of life. (Apparently it's now a pet theory that life did start elsewhere ... maybe on Mars, though see David's latest post about meteorites.) But if it couldn't/didn't evolve, it wouldn't be OUR type of life. In any case, if our type of life started somewhere else, we are still faced with the same mysteries. How did the mechanisms put themselves together in the first place?-Another pie-in-the-sky RNA world self-replicating and copying RNA, made by intelligence in a lab. The first since R18, many years ago, and based on it, imploying many thousands of variations on R18. Oh, well:-http://www.newscientist.com/blogs/shortsharpscience/2011/04/rna-enzyme-makes-another-rna-e.html-Even if this research continues, it proves nothing, except humans can invent realities. We can never know if this is the way it happened.
