This is a journey of self-discovery. Why ordinary people are capable of doing extraordinary things? Why we risk danger even death to save our children even a stranger? Millions of years of evolution has made us generous to our families.
This is a journey of self-discovery. I want to find out why ordinary people like you and I are capable of doing extraordinary things; why we risk danger even death for the sake of another; why did this woman make the ultimate sacrifice;what made this soldier run into a hail of bullets; what gave these two men the courage to rescue a complete stranger. In our quest to understand our instincts to help others, we'll find out how we are programmed to love and protect our children from birth.
We'll travel across the globe to discover the surprising instincts we share with gruesome vampires. With intriguing experiments, we'll reveal how millions of years of evolution have made us generous to our families. And I'll have my brain probed to learn how human beings could read each other's minds.
And we'll go right to the edge of our scientific knowledge to understand how the most uniquely human instinct has helped us to become the most successful species on the planet, the instinct to put others first.
Our story begins here, in this beautiful part of southern France. The Gorge de la Nesk in Provence was once home to early humans. The relics these first inhabitants left have been gradually uncovered by scientists over the last 15 years. Recently they've made an extraordinary discovery, the earliest evidence of human kindness, and I am on my way to see it for myself.
200,000 years ago in this stunning gorge, early humans settled in the overhangs of cliffs. And it's in one of these rock shelters that archaeologists unearthed their remarkable find. This tiny fossil has a huge story to tell. It's the right half of an early human jawbone and we can see that the teeth fell out while this human was still alive. As eaters of tough meat, this would have meant certain starvation, a death sentence, but for this person hope was at hand.
