I have read that the Catholic Church is not anti evolution theory. However, if this is the case where does that leave Adam and Eve and original sin? Can you hold a belief in Adam and Eve as well as evolution? If so how does it work in practice i.e.at what stage in evolution did the original sin occur?
Tim,
The short answer is, yes you can hold a belief in Adam and Eve as well as evolution

. I certainly do
I think what you are more interested in is how the two can be reconciled.
The first thing that should be considered is that many people tend to mistake the Theory of Evolution, which describes the mechanisms of how animals changed over time and how the physical structures of the human species developed with the materialistic philosophy that many (but by no means all) scientists hold. My one personal belief is that Evolution is the mechanism God used to develop bodies that were suitable for us. The process may have appeared random, but only because we are unable to directly see God’s role in that process.
Now as to the question of the Fall; there are two possible approaches, that I can think of. I don’t strongly hold either one, but rather consider both to be possibilities.
The first is, as another poster described, a situation where Adam and Eve (or at least some small group of early humans) were given souls and then committed sins. Their ancestors thus inherited that sin.
The other possibility is that Adam and Eve’s sin was not an historical event. I.e., it happened, but not inside what we would recognize our Universe or Time. If that is the case, this Universe may well have been created as a place that man has been exiled to while Salvation History is worked out by God. I tend to like this version myself because it allows for the introduction of Death, the exile from the Garden, and it can explain why our World can be so inhospitable at times.
