Elephants all the way down.
Seriously, though, the General Theory of Evolution is science fiction. After all those years, scientists have still been unable to really prove it.
Yes, there is genetic modification, and intraspecies evolution. But general evolution out of nothing simply doesn’t compute. The Church is open to the idea, since it does not take the creation date literally. (What do “days” mean in Genesis, for instance, before the creation of light, or of the sun and the moon? Presumably unspecified lengths of time.)
As a Catholic, I have no religious problem with evolutionary theory. But as someone with an interest in science, I have never thought it really made sense, ever since I was introduced to it in school.
Of course not. But I bet if some scientist came up with a purely naturalistic explanation for the "virgin birth" you'd have a problem with it.
