what did christophercolumbus discover and how did the native americansocieties compare to europe

When Christopher Columbus and his crew arrived in the New World, two biologically singled-out worlds were brought into contact. The fauna, plant, and bacterial life of these 2 worlds began to mix in a procedure chosen the Columbian Exchange. The results of this exchange recast the biology of both regions and altered the history of the earth.

Geologists believe that betwixt 280 million and 225 1000000 years ago, the earth's previously separate country areas became welded into a landmass called Pangaea. Nearly 120 one thousand thousand years ago, they believe, this landmass began to separate. As this happened, the Atlantic Sea formed, dividing the Americas from Africa and Eurasia. 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 split biological worlds. However, when Christopher Columbus and his crew made country in the Bahamas in October 1492, these 2 long-separated worlds were reunited. Columbus' voyage, along with the many voyages that followed, disrupted much of the biological segregation brought about past continental drift.

After Columbus' arrival in the Americas, the animal, found, and bacterial life of these ii worlds began to mix. This process, kickoff studied comprehensively by American historian Alfred Crosby, was called the Columbian Exchange. By reuniting formerly biologically distinct land masses, the Columbian Commutation had dramatic and lasting furnishings on the world. New diseases were introduced to American populations that had no prior experience of them. The results were devastating. These populations as well were introduced to new weeds and pests, livestock, and pets. New food and fiber crops were introduced to Eurasia and Africa, improving diets and fomenting merchandise there. In addition, the Columbian Exchange vastly expanded the scope of production of some pop drugs, bringing the pleasures — and consequences — of coffee, sugar, and tobacco use to many millions of people. The results of this exchange recast the biological science of both regions and contradistinct the history of the world.

The period from east to west: Disease

By far the near dramatic and devastating impact of the Columbian Exchange followed the introduction of new diseases into the Americas. When the first inhabitants of the Americas arrived across the Bering land bridge between 20,000 and 12,000 years ago, they brought few diseases with them. Why? For one reason, they had no domesticated animals, the original source of homo diseases such as smallpox and measles. In addition, every bit they passed from Siberia to North America, the offset Americans had spent many years in extreme cold, which eliminated many of the disease-causing agents that might have traveled with them. As a result, the get-go Americans and their descendants, possibly 40 million to sixty million strong by 1492, enjoyed freedom from almost of the infectious diseases that plagued populations in Afro-Eurasia for millennia. Meanwhile, in Asia and Africa, the domestication of herd animals brought new diseases spread by cattle, sheep, pigs, and fowl.

Soon after 1492, sailors inadvertently introduced these diseases — including smallpox, measles, mumps, whooping cough, influenza, chicken pox, and typhus — to the Americas. People who lived in Afro-Eurasia had developed some immunities to these diseases because they had long existed among well-nigh Afro-Eurasian populations. However, the Native Americans had no such immunities. Adults and children alike were stricken by wave after moving ridge of epidemic, which produced catastrophic bloodshed throughout the Americas. In the larger centers of highland United mexican states and Republic of peru, many millions of people died. On some Caribbean islands, the Native American population died out completely. In all, betwixt 1492 and 1650, perhaps 90 percent of the showtime Americans had died.

This loss is considered among the largest demographic disasters in human history. By stripping the Americas of much of the human population, the Columbian Exchange rocked the region's ecological and economical residual. Ecosystems were in tumult as forests regrew and previously hunted animals increased in number. Economically, the population decrease brought by the Columbian Exchange indirectly caused a drastic labor shortage throughout the Americas, which eventually contributed to the establishment of African slavery on a vast calibration in the Americas. By 1650, the slave trade had brought new diseases, such as malaria and xanthous fever, which further plagued Native Americans.

The flow from eastward to w: Crops and animals

Eurasians sent much more than disease westward. The introduction of new crops and domesticated animals to the Americas did almost as much to upset the region'southward biological, economic, and social balance as the introduction of affliction had. Columbus had wanted to establish new fields of plenty in the Americas. On his afterward voyages he brought many crops he hoped might flourish at that place. He and his followers brought the familiar food grains of Europe: wheat, barley, and rye. They besides brought Mediterranean plantation crops such as sugar, bananas, and citrus fruits, which all had originated in South or Southeast Asia. At showtime, many of these crops fared poorly; simply eventually they all flourished. After 1640, sugar became the mainstay of the Caribbean and Brazilian economies, becoming the foundation for some of the largest slave societies ever known. The production of rice and cotton wool, both imported in the Columbian Exchange, together with tobacco, formed the basis of slave society in the United States. Wheat, which thrived in the temperate latitudes of N and Southward America and in the highlands of United mexican states, somewhen became a fundamental food crop for tens of millions of people in the Americas. Indeed, by the tardily 20th century, wheat exports from Canada, the United states, and Argentine republic were feeding millions of people outside the Americas. It is truthful that the spread of these crops drastically changed the economic system of the Americas. However, these new crops supported the European settler societies and their African slave systems. The Native Americans preferred their own foods.

When it came to animals, yet, the Native Americans borrowed eagerly from the Eurasian stables. The Columbian Exchange brought horses, cattle, sheep, goats, pigs, and a collection of other useful species to the Americas. Earlier Columbus, Native American societies in the high Andes had domesticated llamas and alpacas, but no other animals weighing more than than 45 kg (100 lbs). And for good reason: none of the other 23 big mammal species present in the Americas before the arrival of Columbus were suitable for domestication. In contrast, Eurasia had 72 large animal species, of which 13 were suitable for domestication. So, while Native Americans had plenty of good food crops available before 1492, they had few domesticated animals. The main ones, bated from llamas and alpacas, were dogs, turkeys, and guinea pigs.

Of all the animals introduced by the Europeans, the equus caballus held detail allure. Native Americans outset encountered it every bit a fearsome war beast ridden by Spanish conquistadors. Nonetheless, they shortly learned to ride and heighten horses themselves. In the North American great plains, the arrival of the horse revolutionized Native American life, permitting tribes to hunt the buffalo far more effectively. Several Native American groups left farming to get buffalo-hunting nomads and, incidentally, the most formidable enemies of European expansion in the Americas.

Cattle, sheep, pigs, and goats as well proved popular in the Americas. Within 100 years after Columbus, huge herds of wild cattle roamed many of the natural grasslands of the Americas. Wild cattle, and, to a lesser degree, sheep and goats, menaced the food crops of Native Americans, notably in Mexico. Eventually ranching economies emerged, based variously on cattle, goats, or sheep. The largest ranches emerged in the grasslands of Venezuela and Argentina, and on the broad sea of grass that stretched from northern United mexican states to the Canadian prairies. Native Americans used the livestock for meat, tallow, hides, transportation, and hauling. Altogether, the suite of domesticated animals from Eurasia brought a biological, economic, and social revolution to the Americas.

The flow from west to e: Disease

In terms of diseases, the Columbian Exchange was a wildly unequal affair, and the Americas got the worst of it. The menses of disease from the Americas e into Eurasia and Africa was either footling or consisted of a single important infection. Much less is known about pre-Columbian diseases in the Americas than what is known most those in Eurasia. Based on their study of skeletal remains, anthropologists believe that Native Americans certainly suffered from arthritis. They also had another disease, probably a form of tuberculosis that may or may not have been similar to the pulmonary tuberculosis common in the modern world. Native Americans as well patently suffered from a group of illnesses that included two forms of syphilis. One controversial theory asserts that the venereal syphilis epidemic that swept much of Europe offset in 1494 came from the Americas; however, the bachelor evidence remains inconclusive.

The catamenia from west to east: Crops and cuisine

America's vast contribution to Afro-Eurasia in terms of new found species and cuisine, however, transformed life in places as far apart as Republic of ireland, Due south Africa, and China. Before Columbus, the Americas had enough of domesticated plants. By the time Columbus had arrived, dozens of plants were in regular use, the virtually important of which were maize (corn), potatoes, cassava, and various beans and squashes. Bottom crops included sweetness white potato, papaya, pineapple, tomato plant, avocado, guava, peanuts, chili peppers, and cacao, the raw grade of cocoa. Inside 20 years of Columbus' last voyage, maize had established itself in North Africa and possibly in Spain. It spread to Egypt, where it became a staple in the Nile Delta, and from in that location to the Ottoman Empire, especially the Balkans. By 1800, maize was the major grain in large parts of what is now Romania and Serbia, and was besides important in Hungary, Ukraine, Italia, and southern France. It was often used as fauna feed, simply people ate it as well, commonly in a porridge or staff of life. Maize appeared in China in the 16th century and eventually supplied about one-10th of the grain supply there. In the 19th century information technology became an important ingather in Republic of india. Maize probably played its greatest role, however, in southern Africa. In that location maize arrived in the 16th century in the context of the slave trade. Southern African environmental conditions, across what is now Angola, Republic of zambia, Zimbabwe, Mozambique, and eastern South Africa, suited maize handsomely. Over the centuries, maize became the primary peasant food in much of southern Africa. In late 20th-century South Africa, for instance, maize grew in two-thirds to three-quarters of the region's cropland.

Despite maize'southward success, the humble potato probably had a stronger impact in improving the food supply and in promoting population growth in Eurasia. The murphy had little impact in Africa, where conditions did not suit it. But in northern Europe the tater thrived. It had the most pregnant effect on Ireland, where it promoted a rapid population increment until a spud bane ravaged the crop in 1845, bringing widespread famine to the surface area. Later on 1750, Scandinavia, the Low Countries, Federal republic of germany, Poland, and Russia also gradually accustomed the potato, which helped bulldoze a general population explosion in Europe. This population explosion may accept laid the foundation for world-shaking developments such as the Industrial Revolution and modernistic European imperialism. The potato also fed mountain populations around the world, notably in China, where it encouraged settlement of mountainous regions.

While maize and potatoes had the greatest world historical importance of the American crops, bottom crops made their marks as well. In W Africa, peanuts and cassava provided new foodstuffs. Cassava, a tropical shrub native to Brazil, has starchy roots that will grow in almost whatsoever soil. In the leached soils of West and Central Africa, cassava became an indispensable ingather. Today some 200 meg Africans rely on information technology as their primary source of nutrition. Cacao and rubber, two other S American crops, became important export items in West Africa in the 20th century. The sweet murphy, which was introduced into China in the 1560s, became China'southward third almost important crop after rice and wheat. Information technology proved a useful supplement to diets throughout the monsoon lands of Asia. Indeed, almost everywhere in the world, one or another American nutrient crops caught on, complementing existing crops or, more than rarely, replacing them. By the late 20th century, about one-third of the globe'due south food supply came from plants starting time cultivate in the Americas. The modern rise of population surely would accept been slower without them.

In dissimilarity, the animals of the Americas have had very niggling bear upon on the balance of the world, unless one considers its earliest migrants. The camel and the equus caballus actually originated in North America and migrated westward across the Bering country bridge to Asia, where they evolved into the forms familiar today. By the time of the Columbian Substitution, these animals were long extinct in the Americas, and the majority of America's domesticated animals would have little more than than a tiny affect on Afro-Eurasia. One domesticated animal that did have an effect was the turkey. Wild animals of the Americas have done only a petty ameliorate. Probably afterwards the 19th century, North American muskrats and squirrels successfully colonized large areas of Europe. Deliberate introductions of American animals, such as raccoons fancied for their fur and imported to Germany in the 1920s, occasionally led to escapes and the establishment of feral animal communities. Still, no species introduced from the Americas revolutionized human diplomacy or brute ecology anywhere in Afro-Eurasia. In terms of animal populations equally with disease, the Americas contributed little that could flourish in the conditions of Europe, Africa, or Asia.

The Columbian Exchange in the modern earth

As the late dates of the introduction of muskrats and raccoons to Europe suggest, the Columbian Exchange continues into the present. Indeed, it will surely keep into the future as modern transportation continues the pattern begun by Columbus. Recently, for example, zebra mussels from the Black Sea, stowed away in the ballast water of ships, invaded Northward American waters. There they blocked the h2o intakes of factories, nuclear power plants, and municipal filtration plants throughout the Great Lakes region. Just equally the arrival of Christopher Columbus's ships in America in the 15th century resulted in the worldwide exchange of disease, crops, and animals, the 20th-century practice of ships using water equally anchor helped unite the formerly diverse flora and beast of the earth's harbors and estuaries. Similarly, air send allows the spread of insects and diseases that would not easily survive longer, slower trips. Mod transport carries on in the tradition of Columbus by promoting a homogenization of the world's plants and animals. To appointment, withal, the world historical importance of modernistic exchanges pales beside that which took place in the original Columbian Exchange.
