1493: Uncovering the New World Columbus Created Read Free Page B

On the edge of town, a church, built in 1994 but already showing signs of age, commemorates the first Catholic Mass celebrated in the Americas. Watching the waves from the admiral’s ruined home, I could easily imagine disappointed tourists thinking that the colony had left nothing meaningful behind—that there was no reason, aside from the pretty beach, for anyone to pay attention to La Isabela. But that would be a mistake.
    Babies born on the day the admiral founded La Isabela—January 2, 1494—came into a world in which direct trade and communication between western Europe and East Asia were largely blocked by the Islamic nations between (and their partners in Venice and Genoa), sub-Saharan Africa had little contact with Europe and next to none with South and East Asia, and the Eastern and Western hemispheres were almost entirely ignorant of each other’s very existence. By the time those babies had grandchildren, slaves from Africa mined silver in the Americas for sale to China; Spanish merchants waited impatiently for the latest shipments of Asian silk and porcelain from Mexico; and Dutch sailors traded cowry shells from the Maldive Islands, in the Indian Ocean, for human beings in Angola, on the coast of the Atlantic. Tobacco from the Caribbean ensorcelled the wealthy and powerful in Madrid, Madras, Mecca, and Manila. Group smoke-ins by violent young men in Edo (Tokyo) would soon lead to the formation of two rival gangs, the Bramble Club and the Leather-breeches Club. The shogun jailed seventy of their members, then banned smoking.
    Long-distance trade had occurred for more than a thousand years, much of it across the Indian Ocean. China had for centuries sent silk to the Mediterranean by the Silk Road, a route that was lengthy, dangerous, and, for those who survived, hugely profitable. But nothing like this worldwide exchange had existed before, still less sprung up so quickly, or functioned so continuously. No previous trade networks included both of the globe’s two hemispheres; nor had they operated on a scale large enough to disrupt societies on opposite sides of the planet. By founding La Isabela, Colón initiated permanent European occupation in the Americas. And in so doing he began the era of globalization —the single, turbulent exchange of goods and services that today engulfs the entire habitable world.
    Newspapers usually describe globalization in purely economic terms, but it is also a biological phenomenon; indeed, from a long-term perspective it may be primarily a biological phenomenon. Two hundred and fifty million years ago the world contained a single landmass known to scientists as Pangaea. Geological forces broke up this vast expanse, splitting Eurasia and the Americas. Over time the two divided halves of Pangaea developed wildly different suites of plants and animals. Before Colón a few venturesome land creatures had crossed the oceans and established themselves on the other side. Most were insects and birds, as one would expect, but the list also includes, surprisingly, a few farm species—bottle gourds, coconuts, sweet potatoes—the subject today of scholarly head-scratching. Otherwise, the world was sliced into separate ecological domains. Colón’s signal accomplishment was, in the phrase of historian Alfred W. Crosby, to reknit the seams of Pangaea. After 1492 the world’s ecosystems collided and mixed as European vessels carried thousands of species to new homes across the oceans. The Columbian Exchange, as Crosby called it, is the reason there are tomatoes in Italy, oranges in the United States, chocolates in Switzerland, and chili peppers in Thailand. To ecologists, the Columbian Exchange is arguably the most important event since the death of the dinosaurs.
    Unsurprisingly, this vast biological upheaval had repercussions on humankind. Crosby argued that the Columbian Exchange underlies much of the history we learn in the classroom—it was like an invisible wave, sweeping along
