In 50 episodes, we’re going to explore biology—the science of life. Dr. Samuel Ramsey will guide you through life’s vast interconnectedness, telling lesser-known stories of biologists along the way. We’ll discover how evolution, genetics, ecology, and cell and organismal biology deepen our knowledge of every living thing: including ourselves. This course is based on an introductory-level college and AP Biology curriculum. By the end of this course, you will be able to: *Understand what life is and the natural systems that make it possible. *Describe the types of questions biologists answer and the skills they need to answer them. *Explain how life is organized in nested systems that regulate biological activities. *Describe how life on earth has evolved, including the forces driving that change. *Identify ways in which all of life is interconnected and how biology impacts human society. *Use scientific language inclusively and accurately. *Understand the collective nature of biology through examples of innovation and discovery from a wide variety of researchers, civilizations, and cultures, including historically underrepresented scientists and stories Biology textbooks cited include: Taylor, Simon, Dickey, Hogan and Reece (2017); Morris et al. (2019); Clark, Choi, and Douglas; Murray, Cain, Wassherman, Minorsky, & Reece (2016); and Miller and Levine (2019). Check out our new channel, Crash Course en Español, to watch Crash Course Biología!
