I'm not saying that I subscribe to those views, I just threw them out as possibilities. As far as I know the Church has never accepted Darwinism, it just doesn't see anything prior to the Creation of Man as essential to Salvation. You might want to see if you can find a strong Catholic theologian with a science background, they are out there but depending on where you live they may be tough to find.
I'm not sure if science background is the answer when looking at theories of origin. The wisdom of man is something that I am really wary of, and I know that it is the Lord's pleasure to confound the wisdom of those who consider themselves wise apart from Him.
I'm serving in Germany right now. I'll be looking up some local Catholic priests soon.... it's just hard to find American ones.... english speaking ones.... I'm sure there are a few chaplains on the bigger posts and bases.
Thanks!
