What happened in the columbian exchange
The Columbian Exchange: Biological and Cultural Consequences of 1492 by Alfred W. CrosbyThirty years ago, Alfred Crosby published a small work that illuminated a simple point, that the most important changes brought on by the voyages of Columbus were not social or political, but biological in nature. The book told the story of how 1492 sparked the movement of organisms, both large and small, in both directions across the Atlantic. This Columbian exchange, between the Old World and the New, changed the history of our planet drastically and forever.
The book The Columbian Exchange changed the field of history drastically and forever as well. It has become one of the foundational works in the burgeoning field of environmental history, and it remains one of the canonical texts for the study of world history. This 30th anniversary edition of The Columbian Exchange includes a new preface from the author, reflecting on the book and its creation, and a new foreword by J. R. McNeill that demonstrates how Crosby established a brand new perspective for understanding ecological and social events. As the foreword indicates, The Columbian Exchange remains a vital book, a small work that contains within the inspiration for future examinations into what happens when two peoples, separated by time and space, finally meet.

The Columbian Exchange
When Christopher Columbus and his crew arrived in the New World, two biologically distinct worlds were brought into contact. The animal, plant, and bacterial life of these two worlds began to mix in a process called the Columbian Exchange. The results of this exchange recast the biology of both regions and altered the history of the world. About million years ago, they believe, this landmass began to separate. Over the course of the next several million years in both the Americas and in Afro-Eurasia, biological evolution followed individual paths, creating two primarily separate biological worlds. However, when Christopher Columbus and his crew made land in the Bahamas in October , these two long-separated worlds were reunited. This process, first studied comprehensively by American historian Alfred Crosby, was called the Columbian Exchange.
Have you ever heard the expression, "There's no such thing as a free lunch? Oh, and I'll even throw in some new crops you can grow for me. There you pretty much have the essence of the Columbian Exchange. New World meets Old World for the first time since Pangaea split a gazillion years ago. What could go wrong?
The Columbian exchange , also known as the Columbian interchange , named for Christopher Columbus , was the widespread transfer of plants, animals, culture, human populations, technology, diseases, and ideas between the Americas , West Africa, and the Old World in the 15th and 16th centuries. It also relates to European colonization and trade following Christopher Columbus 's voyage. The changes in agriculture significantly altered global populations. The most significant immediate impact of the Columbian exchange was the cultural exchanges and the transfer of people both free and enslaved between continents. The new contact between the global population circulated a wide variety of crops and livestock, which supported increases in population in both hemispheres, although diseases initially caused precipitous declines in the numbers of indigenous peoples of the Americas.
The Columbian exchange of crops affected both the Old World and the New. Amerindian crops that have crossed oceans—for example, maize to China and the.

The Columbian Exchange - description for kids
View a visualization of the Columbian Exchange. That separation lasted so long that it fostered divergent evolution; for instance, the development of rattlesnakes on one side of the Atlantic and vipers on the other. After , human voyagers in part reversed this tendency. Their artificial re-establishment of connections through the commingling of Old and New World plants, animals, and bacteria, commonly known as the Columbian Exchange, is one of the more spectacular and significant ecological events of the past millennium. When Europeans first touched the shores of the Americas, Old World crops such as wheat, barley, rice, and turnips had not traveled west across the Atlantic, and New World crops such as maize, white potatoes, sweet potatoes, and manioc had not traveled east to Europe. In the Americas, there were no horses, cattle, sheep, or goats, all animals of Old World origin. Among these germs were those that carried smallpox, measles, chickenpox, influenza, malaria, and yellow fever.
