In my opinion, biology is about just two things: the why and how. The why is evolution. The how is protein synthesis.
Evolution is basically just applied game theory. Protein synthesis is basically nanotechnology which is basically self-replicating information systems. Combine the two and you can explain just about everything about living systems.
You can learn these two relatively simple concepts in a few days. Everything you learn about biology afterwards will be filling in details. Most students who spend years in biology classes understand neither.
If you learn the game theory behind evolution, you will understand much more than biology. Human psychology and behavior, individual, social, economic, and political can be understood as a set of iterated game theory scenarios. You cannot truly understand history or society until you can see them in terms of game theory principles.
