Great Ideas in Biology
Life on Earth began more than two billion years ago. In this seminar, we will begin by discussing scientific theories about the origins of life. We will trace the evolution of life from two billion years ago to today, by trying to understand the mechanisms it had to invent and then evolve into the enormous diversity of life we see around us. Examples of some of these inventions are the genetic code, mechanisms of energy production, the complex cell, sex, motion, vision, hot blood, consciousness, and death. Our discussions will broadly follow the structure of the book, Life Ascending: The Ten Great Inventions of Evolution by Nick Lane.
