Human migration northward was made possible by a revolutionary technology – the mastery of fire. Having learnt to walk upright, this particularly successful primate could now use his hands to strike a spark from a flint and set fire to dry grass. By gathering and burning the first non-edible resources – brushwood and reeds – people were able to control the temperature in their lairs or caves. Now that they were able to cook food over a fire, people consumed seeds, beans and bones that they couldn’t digest raw. Practically everything that humans have made subsequently – terracotta and brick, bronze and iron, salt and sugar, petrol and plastic – they have made in collaboration with fire. In the myth of Prometheus, the hero steals fire from the gods, hides it in the hollow centre of a reed and carries it to humanity. The gods’ revenge is long-drawn-out and cruel. All the details of the myth are significant – from the hero on the frontier between two worlds to the humble reed, with which the whole story begins.

The mastery of fire was the first practical act in which brain was more important than brawn. After a fire, forests were more productive, there was more game and the predators disappeared. A fire in the hearth tamed humankind. Armed with fire, humankind could tame nature. These hunters, whose only weapons consisted of cudgels or sticks, burnt forests to create great swathes of natural golf courses. This is how the American prairies were created, and probably the Eurasian steppes as well. For their physical survival, each human being needs to consume between 2,000 and 4,000 kilocalories per day. The production of a daily portion of the modern, meat-rich diet takes approximately 10,000 kilocalories of solar energy. Human muscles convert food into work, but most of the energy we use comes from elsewhere. In ancient Rome the consumption of non-food energy, most of it through the burning of wood, reached 25,000 kilocalories per person. In the modern world the energy consumption per person is 50,000 kilocalories per day, and in developed countries it is five times higher.¹ In 1943, the anthropologist Leslie White defined culture as the harnessing of energy with the help of technology.² Solar energy, which reaches our wicked world straight from the nearest star, is available to human beings in various forms: wind, water currents, firewood, fossil fuel and food. No energy is produced by human beings; it all comes from the sun. The only exception to this rule of thumb is nuclear energy; perhaps that’s why it is difficult for humans to harness it.

We learnt to cut wood and plough the earth once we had acquired the ability to attach a stone tip to a wooden handle. Wood was abundant, but rare flint was needed for the tip. In axes, crude stone was replaced with flint in about 4000 bce. Found all over Europe, flint axes and knives were produced in great quantities – about half a million every year. But there were very few flint mines. Axe heads originating from one flint deposit in the Alps have been found all over Western Europe. Axes from central Poland have been discovered 800 kilometres away.³ So the earliest human tool, the flint axe, already combined two types of raw material – the easily replaceable stick and the precious flint, which was handed down from one generation to another, travelling huge distances on its way. The owners had to protect the sites where flint was found, and the first property rights developed. Others had to produce something of value to exchange: a flock of sheep, for example, or cured hides. This is how trade began.

For almost all of history, people lived in autonomous groups, communities or tribes. They fed themselves from the land on which they lived. When they had exhausted it they moved on to another plot and again burnt the forest. Fire helped to produce excellent harvests. Mature trees survived forest fires, and cereals or vegetables were sown around them. Field and forest existed side by side, and animals helped people clear the land. Horses and oxen hauled timber, pigs and sheep devoured grass and roots. It required about an acre of cleared forest to support one human being. Any growing population needed to expand the land available for burning and sowing. Like all technological revolutions, fire liberated people and reduced their dependence on nature. But no sooner had he achieved symbiosis with fire than bipedal man fell into the resource trap. In his quest for freedom and happiness, he was constantly destroying the very resource that made him prosper.

Groups of people moved from place to place looking for firewood. These people had neither maps nor even word-of-mouth information about their environment. When they found a forest they could use, they settled there until they had burnt everything flammable. In need of timber, humankind migrated north, to the wooded tracts of Europe. But there were already similar creatures living there – the Neanderthals. Shorter but more heavily built than Homo sapiens, the Neanderthals were intelligent and aggressive. They lived in small communities, were capable of collective action and used fire and stone tools. They coped with the cold climate more easily than H. sapiens. Their brains were bigger than the brains of early modern humans, their sight was sharper, their muscles stronger. For five millennia, H. sapiens and Neanderthals lived side by side in Europe, mating and learning from each other. Then the Neanderthals died out. Archaeologists have found teeth marks from H. sapiens on their bones: early humans had eaten Neanderthals. The anthropologist Pat Shipman has proposed that the main difference between the Neanderthals and the ancestors of modern man was the symbiosis between man and wolf. Homo sapiens and wolves complemented one another. One species could track game; the other could kill it. One was swift-footed and had a superb sense of smell; the other had a big brain and tools. Hunting with dogs gave early humans their greatest advantage over Neanderthals.⁴

American archaeologists investigated adjacent settlements of humans and Neanderthals in the mountains of the Southern Caucasus. The main source of food there was the Caucasian goat. Both groups knew this animal’s seasonal migration routes and settled in the vicinity. They behaved more like breeders than hunters, eating only adult animals and leaving the juveniles to mature. The Neanderthals lived in smaller groups than the humans. Their tools were more primitive because they made them out of local stone. In the human camps the archaeologists found knives made of obsidian, the nearest source of which was 100 kilometres away. With these knives, humans could split strong bones into needles.⁵ These implements were highly prized and used over and over again for scraping skins and sewing them together, making clothes and shoes. These goods entailed a huge amount of labour, but they could be exchanged for other things such as obsidian. This is probably the first example of long-distance trade in human history, but the pattern was fully developed: a rare, distant natural resource was exchanged for products of human labour.

Having left their subtropical Eden, humans needed to dress in furs and skins. The Neanderthals had more subcutaneous fat and more body hair, and they did not need fur garments in the temperate climate. They could scrape animal skins but used them as bedding. In contrast to the human traders who exchanged sheep and skins for obsidian, the Neanderthals lived by subsistence farming. Along with dogs, trade gave humankind an advantage in its first battle for survival. Perhaps humans’ symbiosis with wolves was connected to their ability to carry out trade. Hunting with dogs relies on the ability to relate to another creature who has different needs from your own. This is also the basis of trade.
