Why do you expect your Physics professor to teach you biology? Take an entry level biology course and they will teach it to you. One of the basic "rules" in science is to only teach what your an expert in if it can be at all helped. So a physics professor isn't qualified to teach you about biology, nor has any reason to, because his goal is to teach you physics.
What kind of physics program are you in? I'm burned out with physics, I just took a final in an intro to quantum mechanics course last night. I did fairly well I think, considering its mind numbing to try to conceptialize whats going on.
I finished my degree many years ago. Even so retired as I am, I keep my math up so I can keep up with what is going on now and understand what Lisa Randall is talking about.
If I want to talk evolution I will walk across the quad to the Political Science/Psychology/Philosophy building. They use it a lot more than the Biology Dept does.
