Biology is the study of living organisms, and it has been around almost as long as civilization itself. It’s an incredibly broad discipline with an intricate and elaborate network of sub-disciplines. The five unifying elements of biology are genetics, cell theory, energy, evolution, and homeostasis. The origins of modern biology are usually traced back to ancient Greece, where the formal study of medicine and anatomy began with Hippocrates. Rare books about biology are valuable not only as beautiful objects, but also as artifacts reflecting our collective knowledge and understanding during any given era. Biology books make fascinating additions to any personal library.
