Biology Concepts and Processes

Mr. Andersen provides an overview of biology, highlighting its diverse disciplines and the four major themes: evolution, free energy, information, and systems. He explains evolution through natural selection, using examples like the peppered moths. The concept of free energy is discussed in terms of energy flow and homeostasis. Information flow is explained through DNA's role in genetics and cell communication. Finally, the hierarchy of life and system interactions are explored, emphasizing the importance of emergent properties and biodiversity.
