how, if at all, does catholicism inform your work in evolution?
It doesn't directly. But it doesn't tell me that God created things directly. The Genesis is a representation of how things start from less to more complicated.
I have developed sort of my own theory for what we call the soul. For me the human brain developed to such an extent that conceives of something else beyond what we can see. It searches for explanations. When we have to explanations it searches for a higher force.
I don't see that the higher force would have to have any hand on how we developed as humans but development of a religious brain is probably inevitable as our curiosity increases and our imagination too.
Religion for me is how we develop a relationship with that force, how we try to understand it.
As a Christian the biggest gap is Christ himself. I can't explain it and won't try to, but what he taught makes more than perfect sense to me and certainly one of the best ways to counteract our egotistical and violent nature. (Not the devil, btw, we all have some "evil" or are capable of it and we choose what we do)
As a note I find it curious that someone I know who became atheist believes that homeopathy works. That, I'd say, requires compartmentalization.
Anyway, religion as I practice it doesn't affect the science I do and could never follow one that simply ignores science.
