Trade explores the civilizing effect of buying and selling goods. In particular, the Indus Valley Civilization – on the borders of modern-day India and Pakistan – was seemingly created with the single purpose of encouraging the free flow of trade. The knock-on effects were massively beneficial - an increase in wealth, co-operation and trust.

War addresses the paradox that good comes from bad. The threat of destruction engenders a sense of fear, but also creates tighter bonds within a community, while driving an arms race of technological progress. This happened in the Zapotec civilization in Mexico, but also with the Teotihuacan civilization which overthrew the Zapotecs and emerged as the first superpower of the Americas.

As early humans spread out across the world, their toughest challenge was colonizing the Americas - because a huge ice sheet blocked the route. It has long been thought that the pioneers, known as Clovis people, arrived about 13,000 years ago, but an underwater discovery in Mexico suggests people arrived earlier than previously thought - and by boat, not on foot. How closely related were these First Americans to today's Native Americans? It's a controversial...

Around 200,000 years ago, a new species, Homo sapiens, appeared on the African landscape. While scientists have imagined eastern Africa as a real-life Garden of Eden, the latest research suggests humans evolved in many places across the continent at the same time. DNA from a 19th-century African-American slave is forcing geneticists to re-think the origins of our species. The theory is that our ancestors met, mated and hybridized with other human...

What happened when early humans ventured out of Africa and into Asia? Where did they go and whom did they meet along the way? The latest evidence suggests they left far earlier than previously thought and interbred with other types of ancient human - Homo erectus, Neanderthals and also the Denisovans, whose existence was established only five years ago when geneticists extracted DNA from a tiny fragment of finger bone. Because these ancient humans...

"Today, society embraces sharing like never before. Fueled by our dependence on mobile devices and social media, we have created an ecosystem of obsessive connection. Many of us now lead lives of strangely crowded isolation: we are always linked, but only shallowly so. The capacity to be alone, properly alone, is one of life's subtlest skills. Real solitude is a powerful resource we can call upon|a crucial ingredient for a rich interior life. It inspires...

A shattering account of the crack cocaine years from award-winning American historian David Farber, Crack tells the story of the young men who bet their lives on the rewards of selling 'rock' cocaine, the people who gave themselves over to the crack pipe, and the often-merciless authorities who incarcerated legions of African Americans caught in the crack cocaine underworld. Based on interviews, archival research, judicial records, underground videos,...

The four Gospels are the source material for this sympathetic account of the life of Jesus, from the traditional account of his birth to his death and resurrection. All the principal episodes are told-his baptism, the Sermon on the Mount, the Last Supper, The Betrayal, The Trial, The Crucifixion-as well as portraits of the principal characters in the story: Mary, Joseph, the Disciples, Mary Magdalene, Pontius Pilate and many others.

In 1987 a massive snowstorm hits New York as Peter Kaldheim flees the city, owing drug debts to a dealer who is no stranger to casual violence. Leaving behind his chaotic past, Kaldheim hits the road, living hand-to-mouth in flop-houses, pan-handling with his fellow itinerants. As he makes his way across America in search of a new life, the harsh reality of living hand-to-mouth forces him to face up to his past, from his time in Rikers prison, to...

When Kent Nerburn received a letter from Jennifer, a young woman questioning her calling to spend her life in the arts, the writer and artist was struck by how closely her questions mirrored the doubts and yearnings of his own youth. Nerburn resolved that he would write his own letter: a letter of welcome and encouragement to all young artists setting out on the same strange and magical journey, sharing the wisdom of a life spent working in the arts....
