Depends on what aspects of darwinism you're using. God most certainly could have used evolution as the means to create the first fully human beings of Adam and Eve.

No, because evolution as we understand it presupposes death before the fall. This has been condemned by the ecumenical councils. They also condemned all metaphorical interpretations of the creation story in Genesis and one can't read a natural determined process like evolution in it if the story is taken literally. Also, what did man evolve from? Did he possess the image and likeness of God in those previous stages and if he did, why did he have to continue evolving? When did that qualitative transition during that process occur (when did man acquire free will)?
