What's so metaphysical about a computer program that exhibits self-replication, energy
transformation to create order, and adaptive evolution?  

In the biological sense, perhaps the DNA/RNA answer is sufficient, but only for
taxonomical reasons. In the not-metaphysical-but-logical-abstraction sense, DNA/RNA is
just a medium for encoding the program that operates the cellular machine. 

Us computer types call that a meta-abstraction (not to be confused with a metaphysical
or religious concept) -- DNA is not life itself, but information about life. Life
itself is what happens when the information is acted on by the machine (or
cell/virus/whatever) to actually perform the behaviors so encoded.
