    Maybe it is. I think the parent was suggesting directed panspermia-- that the Earth's biosphere is itself a B-vN probe in the process of self-replication. That's one way to do it.

      That's how I read that comment, too. If there are ETs, I really want to know whether they're using DNA with triplet codons that map to the same 20 amino acids.
