Biology is about uncertainty, the unpredictable, and what gets done with it.
Biological specimens are the things that adapt and change in the face of the unexpected, other stuff just reacts without adaptation. The rocks are weathered but do not build houses to slow the weathering. All of the certainties of biology are all of the boring parts, the parts that require no thought and no decisions. However, the boring parts are not useless because they form the basis for making guesses about the unpredictable parts that arise out of the predictable. Biology and life is not utterly unpredictable and chaotic, just some of it.
