For most of the Earth's history, life consisted of the simplest organisms; but then something happened that would give rise to staggering diversity, and, ultimately, life as complex as that which we see today. Scientists are still struggling to figure out just what that was.

Do psychedelic drugs really bring about self-healing and personal enlightenment? New research says they may. In this episode, I travel to the Amazonian jungle of Peru to experience the mind-expanding effects of the psychedelic brew Ayahuasca.
What if each of us could make the symptoms of an illness disappear? Cast a spell so powerful it would actually rid us of pain, help us walk, or breathe better? For centuries placebos have been thought of as fake medicine involving trickery and deceit, but Brain Magic: The Power of Placebo pulls back the curtains on the proof that placebos can have powerful – and real – effects on our mind and body. New research is proving that everything from sugar pills, to saline injections, to sham surgery, can have real healing power. Placebos won’t shrink tumours or cure diabetes, but they can be effective in subjective conditions – where self-appraisal plays a role. And, as we’ll discover in Brain Magic, neuroscience is revealing how our bodies’ response to treatment is heavily influenced by our expectations, prior experiences, our beliefs, and the social cues that surround us.
Michael Mosley and a team of experts place human behaviour under the microscope. In the final episode, Michael and scientists Dr Jack Lewis and Dr Jennifer Wild explore the biology of fear and anxiety in the modern world. Fear is one of our most basic human emotions. In the past, it kept us from being eaten by a wild animal. But today, that isn't so much of a threat and yet we live in a state of anxiety - it's becoming unhealthy.
Personality explores what it is that makes us who we are and uncovers the universal battle we face to master our emotions and control our behaviour. Professor Robert Winston explores how our minds shape our personalities throughout our lives, and reveals how personality traits like extroversion and introversion develop.
Neuroscientist David Eagleman explores the human brain in an epic series that reveals the ultimate story of us, why we feel and think the things we do. This ambitious project blends science with innovative visual effects and compelling personal stories, and addresses some big questions. By understanding the human brain, we can come close to understanding humanity. Part 3: Who is in Control ‘Who Is in Control?’ explores the great deception that greets us each morning when we awake: it feels as though we are in conscious control of our lives but the truth is that we are not. Instead almost every action, every decision, every belief that we hold is driven by parts of the brain that we have no access to.
