I recently spent a weekend at this conference on ethics and astrobiology

There was much talk of the beginnings of life and current ongoing research.

I like your ice cube analogy, though they wouldn't call that "replication" but the larger and looser category of "repetitive creation." Replication would require that the ice cubes somehow participate in their own copying process.

Oh nope, what i've meant is yeap - "repetitive creation", and more passive of an action than participation in their own copying process like you've mentioned :)
