Biology That Makes Us Tick: Free Stanford Course by Robert Sapolsky

It doesn’t take long for Robert Sapolsky, one of Stanford’s finest teachers, to pull you right into his course. Better to watch him than listen to me. Second thing to know: Sapolsky is a MacArthur Fellow, a world renowned neurobiologist, and an adept science writer best known for his book, Why Zebras Don’t Get Ulcers. Much of his research focuses on the interplay between the mind and body (how biology affects the mind, and the mind, the body), and that relationship lies at the heart of this course called “Human Behavioral Biology.”

Now the third: Human Behavioral Biology is available on YouTube and iTunes for free. 7.014 Introductory Biology. Exploring Life's Origins: Understanding the RNA World. The Complete Work of Charles Darwin Online. Biochemical Society. Genetics and the tree of life. We traditionally think about the tree of life in terms of Kingdoms: plants, animals, fungi, bacteria, etc.

Genetics and the tree of life

Genetics has really revolutionized the way we think about the tree of life and, because our classifications should reflect ancestry (that is, who is more closely related to whom), it has actually called into question a lot of our traditional classifications. Most biologists split up life into three domains: Archaea, Bacteria, and Eucarya (the last of which includes animals, plants, fungi, etc.). The three domains of life.
