Biology

Mr. Anderson provides an overview of biology, highlighting its various disciplines and the four big ideas: evolution, free energy, information, and systems. He explains evolution with a focus on natural selection, using examples like the peppered moths. The concept of free energy is briefly mentioned. Information transfer, genetics, and cell communication are discussed, emphasizing the importance of genes and signaling pathways. Finally, the hierarchy of life and biological systems are explained, showcasing the organization and emergent properties at different levels.
