1. Adam and Eve were real people that all of humanity is descended from (otherwise, their original sin would not have affected everyone)
2. Adam and Eve were not the product of accidental probabilities (God had intention of them being created)
3. Adam and Eve (and all humans since) have rational, immortal souls created by God (i.e.: the human soul did not evolve)
Catholics are free to believe in any concept of how God created mankind as long as it does not violate the above conditions. Generally, the popes and magisterium of late are open to evolution (of a limited kind compatible with the above statements), but as it is not a teaching about faith or morals, they allow science and reason to work it out.
So they are focusing on their primary line of defense being the acceptance testing.
I'd like 1 kHz worth please.
