Please comment on how the Church deals with evolution.
A very quick response*: As far as I know, there are no magisterial documents that address evolution per se. Pope John Paul II caused a stir when he (correctly) distinguished between the use of evolution as a theory** about biological development and its use as a philosophical system. In effect, he argued that Catholics are free to understand the development of the human species as a process of evolution, but that an analogous application to philosophical, political, or theological questions is off-limits. This makes sense given that evolutionists often jump from "humans evolved over time" to "there is no Creator" or "there is no such thing as a soul." Social reformers have used evolutionary theory to propose all sorts of dangerous political ideas that have nothing to do with how humans developed/evolved biologically. Also, current attempts to explain human behavior in terms of "genetic survival" tell us nothing about why we are here in the first place. The only proper scientific answer to the question "why are we here?' is: we can't tell you.
UPDATE: Consider this book, Creation and Evolution: A Conference with Pope Benedict XVI. I have to warn you--the talks can get very technical.
Several points to keep in mind:
1). There is no single, comprehensive scientific theory about evolution. The broadly construed notion of evolution is actually made up of many other "smaller theories" that purport to describe and explain fossil evidence and biological diversity. Get ten evolutionists in a room and you will have one hundred theories about how it all happens.
2). What almost all evolutionists agree on is that their theories attempt to describe and explain how an already existing species evolves over time. Evolution as a scientific theory does not and cannot tell us why anything exists in the first place.
3). Historically, Christian opposition to evolutionary theory is often based on a literal, fundamentalist interpretation of the creation story in Genesis. Since St. Augustine, the Church has taken this account of creation to be metaphorical in its details but nonetheless true in its central claim: we are creatures of a loving Creator. Evolutionary theory does not and cannot tell us anything about God or His activity in His creation.
4). As a way of describing and explaining the fossil record and contemporary observations about biological development, evolutionary theory is good science, and as such, it tells the truth about biological entities and processes. Aquinas teaches us that truth has a single source: Truth Himself. If evolutionary theory accurately describes and explains the physical evidence available to us, then it is true and cannot contradict the faith.
5). Some evolutionists (cf. Dawkins) go well beyond the biological theory and make philosophical, political, and theological claims that do not follow from the theory itself. The key is to keep evolutionists honest by insisting that they do what they claim to do best: tell us about how biological entities develop over time. Out of their theory alone they have nothing to say about political, spiritual, or religious issues. Of course, evolutionists can hold any opinions that strike their fancy. But these opinions are not given scientific weight simply because they are held by scientists.
6). In modern/contemporary western culture science is to presumed to be the final arbiter of truth. Insofar as science describes and explains the physical world, this is largely true. However, human experience entails far more than the merely physical. Science can tell us how the sun shines. It cannot tell us why. Science can tell us how the universe came to be. It cannot tell us why. When scientists presume to answers outside their methodical purview, they are playing at being philosophers and theologians. The same is true for philosophers and theologians who play at being scientists!
Bottom-line: as a theory about how biological entities develop/evolve over time given a particular environment, evolutionary theory is no threat to the Catholic faith. In fact, if evolutionary theory is true, it is made true by Truth Himself.
* I'm answering this "off the top of my head," i.e. I'm not researching the answer in any substantial way, just commenting informally.
** "Theory" here should not be taken in its commonly understood sense; i.e., a guess or speculation about. In the scientific world, "theory" is understood to be a global explanation of available evidence. The Laws of Thermodynamics are scientific theories insofar as they accurately describe and explain phenomena in the real world. They are not guesses.
