It seems to me that there exists a fundamental conflict between the Catholic Doctrine (or Dogma?) of Original Sin and evolution.
The Church clearly teaches that death came to humans at that moment of disobedience (an act which the Church also asserts was, though figuratively presented in scripture, nevertheless a real event, and not just a metaphor).
Yet, in contrast to the Catholic teaching above, death is necessary for the process of evolution to work, for it is the turnover via death that largely integrates beneficial mutations into a species. So…
**1. If evolution is true, and death occurred prior to the First Human, then Original Sin is refuted.
- If the dogma of Original Sin is true, and death did not occur prior to the First Human, then evolution is refuted.

If Catholics wish to claim that evolution is not incompatible with Original Sin because God infused a higher primate with a soul which became the “first human”, then I would request that they also explain:
A) How it is that death would be viewed by this “Adam” as anything new, and at the very least some sort of punishment.
B) At which point on the evolutionary tree did this “infusion of a soul” occur?
C) If the above questions cannot be reconciled adequately with the evidence of evolution, on what basis should Catholics continue to adhere to the doctrine of Original Sin?
