[Natural Law]

Evolution is a description of the process which God used to introduce life into a dynamic environment. No where does the Church suggest any support for abiogenesis.

So where does that leave in the Incarnation? Think about it before you flame.

[Claud]

I'm not so sure abiogenesis per se has been ruled out.

Augustine dealt with abiogenesis in one of his works (on the Literal Interpretation of Genesis maybe?), on the question of when flies & maggots were created.

Since they were, by the science of the day, considered to be spontaneously generated by rotting meat, he argued that they may well not have been created actually during the first six days but only created potentially. So during Creation, God created the properties in meat such that when it would rot, maggots would spontaneously form in it.

Granted the faulty scientific premise, his argument is still important theologically.
