Biology is a borderline infinite system depending on how deep you go.

We need to be able to model molecular forcefields to be able to model DNA expression to be able to model protein expression to be able to model, layers and layers of higher order molecules just to represent a cell.

Then...you have combining cells to make an organism and the interaction of the organism with its environment which affects all of the above.

I think a monkey will be able to understand how to use a cell phone before humans understand how biology works.
