How about this - read the Wikipedia articles on the subjects you're interested in, and then come back and ask us questions?
The truth is we're bored as hell around here, we love to talk about biology, but don't really get the chance. It'd be more interesting for
us to address your questions directly than to send you off to the library. There's a fair amount of genuine expertise around here, quite a few PhD's, a lot of BA/BS's, and a lot of people doing work
right now in science. If there's one thing you can't get a scientist to shut up about, it's their work.
