I must admit that I’m coming into this in the middle of a debate, but it may be helpful for me to add that the Catholic Church (at least) does not promote a literal reading of every book of the bible. The Bible is not a book, it’s a library…there are multiple genres within it. Genesis, we say, is not meant to be scientific in the same sense as Harry Potter isn’t meant to be historical. The story of Adam and Eve relates a spiritual reality, not a biological/physical one.
As a side note, I actually was having a chat with an agnostic today who told me that homo sapiens was, in fact, descended from one man and one woman. I wasn’t sure if I believed him, and he admitted it was still controversial, but I thought it was an interesting thing to add.
I hope that doesn’t make too much of an interruption…
