Aliens. For real this time.

I vaguely remember an article with Carl Sagan as the interviewee, and he discussed what type of life we might expect to find elsewhere in the Universe. He was (obviously) very doubtful that exactly the same set of circumstances that set up life for carbon based forms on Earth might exist (although, in an almost infinite Universe, I don't know why he would dismiss such possibilities, but I digress...) but he did say that he thought it was possible that organisms could develop along different chemical lines. So, I scanned the above articles, but didn't see if they thought these organisms had adapted to this environment, or if they were of this environment. (Again, a quick scan, but still- if they were the product of their environment, then that seems like it would be pretty interesting stuff).
