Columbus is, of course, a person who has inspired admiration and vilification in almost equal measures. He forged a connection which would see the empires of Europe rising to become global superpowers, while the Eden of the Americas was plundered and its civilisations destroyed. Setting foot on that beach, he sealed the fate of tens of millions of Native Americans and ten million Africans. The impact of that moment would ripple out through history. Until this point, Europe had been something of a backwater – but the establishment of colonies in the New World would change all that. The rise of the West had begun.
And the impact would be felt not just throughout human societies, around the world, but by the species that had become our allies – on both sides of the Atlantic. This contact between Europe and the Americas would quickly turn into a sustained connection between the Old and New Worlds. These supercontinents had been largely separate since the break-up of Pangaea, which began around 150 million years ago. During the Great Ice Age, the Pleistocene, the world went through repeated glaciations. And during the glacial periods, sea levels would fall to such an extent that the north-east tip of Asia would be joined to the north-west corner of North America, via a tract of land known as Beringia – or the ‘Bering land bridge’. This bridge
would allow some interchange of plants and animals between Asia and North America. It was the route by which humans first colonised the Americas, around 17,000 years ago. And yet the ancient, underlying theme of divergence and difference between the flora and fauna of the Old and New Worlds persisted – until the human-mediated transfer of plants and animals which started with Columbus bringing back his pineapples, chilli and tobacco in 1492. Plants and animals which had been contained and separate from each other made that leap across the pond, to find themselves facing new landscapes, new challenges and new opportunities on the opposite side. Cattle and coffee, sheep and sugar cane, chickens and chickpeas, wheat and rye travelled from the Old World to the New. Turkeys and tomatoes, pumpkins and potatoes, Muscovy duck and maize made the reverse journey.
The Columbian Exchange has been described by some as the most significant ecological event on the planet since the dinosaurs were wiped out. It was the beginning of globalisation: the world became not just interconnected but interdependent. But it had a wretched inception.
The fortunes of Europe (and, in due course, Asia and Africa) were transformed by the domesticated species brought back from the New World. Novel crops boosted agriculture and populations began to recover from war, famine and plague. But that was in the Old World. In the Americas, a scene of devastation ensued. Just as plants and animals had followed separate evolutionary trajectories on either side of the Atlantic, the pace and direction of technological change had been different in the Old World compared with the New. The Europeans possessed advanced technology: their military and maritime kit was vastly superior to that of the Native Americans. The immediate consequences of contact, with heart-stopping, dreadful inevitability, were tragic. Disease organisms were also part of that Columbian Exchange: the Europeans brought back syphilis from the Americas, while introducing smallpox there – with disastrous consequences. The indigenous population of the Americas plummeted after conquest. It was decimated: by the middle of the seventeenth century, 90 per cent of the indigenous population had been wiped out.
It’s easy to focus on the power imbalance that existed between the Old and New Worlds in the fifteenth and sixteenth centuries. Human societies had developed in different ways in the Americas and in Europe, but it wasn’t as though the Native Americans were entirely without technology – far from it. When it came to their exploitation of natural resources, they were clearly experts. It’s wrong to see the pre-Columbian Americas as, on the one hand, a natural Garden of Eden, and on the other, an innovation vacuum in need of European inspiration to realise its potential. Native American societies had a rich and diverse history of innovation, and the Americas contained completely independent centres of domestication. Many of the pre-Columbian societies of the Americas were large, urbanised – and already dependent on agriculture.
The Spanish explorers didn’t pluck wild plants, out of relative obscurity, recognise their utility for the first time, and transform them into something which would greatly benefit humanity. What the Europeans found on the other side of the Atlantic were organisms which had already changed away from wildness, over thousands of years – which had already entered into a tightly bound, successful alliance with humans. What Columbus discovered was not only a new land, previously unknown to Europeans, but a wealth of useful, tamed animals and plants – ready-made domesticates.
Among those prizes was that cereal he’d spotted and written about, just four days after landing on San Salvador – the cereal that was not only a staple food but a sacred food for the Aztecs and Incas, whose civilisations would soon be swallowed up by the Spanish Empire: maize.
