BBC ProductionsIn the first episode, Dr Alice Roberts looks at how our skeleton reveals our incredible evolutionary journey. Trekking through the forests of our ancient ancestors, she goes to meet the apes who still live there today - chimpanzees. In six million years we have become very different, and what kick-started this can be found in an extraordinary fossil - Sahelanthropus. A single hole where the spine was attached suggests that our ancestors started the journey to being human by standing upright. We take it for granted, but standing up and walking is surprisingly complex - each step involves the co-ordination of over 200 muscles. Charting the major advances from Australopithecus to Homo erectus and beyond, Alice tells the epic story of human evolution through our body today. New research has uncovered clues in our ankles, waists and necks that show how our ancestors were forced to survive on the open plain - by walking and running for their lives. From the neck down we have inherited the body of our ancestor Homo erectus, who lived on the plains of Africa nearly two million years ago. Finally Alice looks at probably the most important advance in our evolutionary story. A fortuitous by-product of standing up was freeing up our hands. With pressure-sensitive gloves, she demonstrates how the tiniest of anatomical tweaks to our thumbs and little fingers transformed hands that evolved to grasp branches into ones that could use tools. And with our dexterous hands, our species, Homo sapiens, would change the world.

In this second episode Dr Alice Roberts charts how our ancestors' hunt for food has driven the way we look and behave today - from the shape of our face, to the way we see and even the way we attract the opposite sex. Clues to our ancestors' diet can be found in some surprising places. Alice goes in search of a lion kill to find out how the tape worms in lions' food reveal our ancestors were eating the same diet of big game 1.7 million years ago. She puts her teeth to the test to reveal that our teeth have evolved to shear through meat. But by comparing her saliva with that of chimpanzees, she demonstrates that our body is as much designed to eat starch as it is to eat meat. And visiting a tribe of hunter gatherers in Tanzania, who still gather food in a similar way to our ancestors, Alice discovers that starchy tubers are crucial to survival when meat is scarce. The latest research suggests that the way the different sexes found food throughout our evolution has shaped the way we relate to each other today. The way the Hadza tribe share food and form long-term couples is thought to be the origin of love and marriage in all of us. And a fun experiment with Britain's best skateboarders shows they take more risks when women are present - it seems men are designed to show off to attract a mate.

Dr Alice Roberts explores how our species, Homo sapiens, developed its large brain and asks why humans are the only ape of its kind left on the planet today. The evolution of the human mind is one of the greatest mysteries. It is the basis of religion, philosophy and science. We are special because of our extraordinary brain, and to understand why we think and act the way we do, we need to look at where and why our brains evolved. The Rift Valley in Kenya is thought to be the crucible of human evolution, and here Alice examines the fossils in our family tree which reveal our brains have more than quadrupled in size since our ancestors split from chimpanzees. Research investigating sediments and rocks laid down during the period of greatest brain growth suggests a fluctuating environment may have played a part. Drawing on research on social politics in chimpanzees, the cognitive development of children and the tools that have been found littered across the Rift Valley, Alice explores how and why our ancestors brains became so big. Successive species of increasingly large-brained humans migrated around the world - from Homo erectus to heidelbergensis, the Neanderthals to us. It has always been assumed the reason that Homo sapiens succeeded where others failed is to do with our large brains. Comparing skulls it's clear Neanderthals had just as big a brain as us, so why is there only us left? Alice goes to meet Svante Paabo, who is decoding the Neanderthal and human genome, and Clive Finlayson, who is unearthing the Neanderthals' final settlement, to try to find out.

From the moment we first drilled for oil, we opened a Pandora's box that changed the world forever. It transformed the way we lived our lives, spawned foreign wars and turned a simple natural resource into the most powerful political weapon the world has ever known. It's a journey that will help us answer a fundamental question--how did we become so addicted to oil in little more than one human lifetime?

By the early 1950s, a holy trinity of oil, plastics and fertilisers had transformed the planet. But as Professor Iain Stewart reveals, when the oil producing countries demanded a greater share in profits from the Western energy companies, the oil and gas fields of the Middle East became a focus for coup d'états and military conflict.

As we entered the 21st century, the world was guzzling oil, coal and gas like never before. In this concluding episode, Iain Stewart argues we face a stark choice. Do we continue feed our addiction--suck Planet Oil dry--and risk catastrophic climate change, or do we go hell for leather for alternative energy sources; nuclear, renewables, to make the transition from our fossil fuel past to a low carbon future. In which case, how do we make that shift?

Two hundred million years ago the continent we know as Eurasia - "the vast swathe of land that extends from Europe in the West to Asia in the East" - didn't exist. To reveal Eurasia's origins, Professor Iain Stewart climbs up to the "eternal flames" of Mount Chimera in southern Turkey, blazing natural gas that seeps out of the rock. Formed on the seafloor, it shows that where the south of Eurasia is today, there was once a 90-million-square-kilometre ocean known as the Tethys. It is the destruction of the Tethys Ocean that holds the key to Eurasia's formation.

This is the story of how our modern scientific idea of nature, the self-regulating ecosystem, is actually a machine fantasy. It has little to do with the real complexity of nature. It is based on cybernetic ideas that were projected on to nature in the 1950s by ambitious scientists. A static machine theory of order that sees humans, and everything else on the planet, as components - cogs - in a system. But in an age disillusioned with politics, the self-regulating ecosystem has become the model for utopian ideas of human 'self-organizing networks' - dreams of new ways of organising societies without leaders, as in the Facebook and Twitter revolutions, and in global visions of connectivity like the Gaia theory. This powerful idea emerged out of the hippie communes in America in the 1960s, and from counterculture computer scientists who believed that global webs of computers could liberate the world. But, at the very moment this was happening, the science of ecology discovered that the theory of the self-regulating ecosystem wasn't true. Instead they found that nature was really dynamic and constantly changing in unpredictable ways. But the dream of the self-organizing network had by now captured our imaginations - because it offered an alternative to the dangerous and discredited ideas of politics.

This edition of Horizon does something that no one has done before. We have assembled the first ever complete Neanderthal skeleton, from parts gathered from all over the world, to reveal the most anatomically accurate representation of modern humanity's closest relative. The aim is to use this skeleton to answer two of the great questions of human evolution. Was Neanderthal a thinking, feeling human being like us, or a primitive beast? And why is it that we are here today, and Neanderthal is extinct? To answer these questions, we've brought together a team of leading experts to explore the skeleton for clues, and perform experiments to test out their ideas. Their findings allow us to use drama to bring Neanderthal to life with unrivalled accuracy. They reveal how Neanderthal hunted, thought - even spoke. What emerges is a very different beast to the brute of legend. It seems Neanderthal was in many ways our equal and in some ways our superior. And the story of his extinction owed less to modern humans' superiority than sheer luck.
