That separation lasted so long that it cultivated an evolution. For example; the creation and development of rattlesnakes and vipers area product of this drift. After 1492, human voyagers in part reversed this tendency. The re-establishment between the Old world and the New World created new intertwined connections that are a product of animals, plants, and bacteria. Which is the outcome of the Colombian Exchange. This exchange possesses a spectacular and significant ecological event that have shaped Europeans and Native Americans amid this time, and soon the world. Europeans originally contacted the shores of the Americas. The Old-World assortment of crops such as “wheat, barley, rice, and turnips had not traveled west across the Atlantic, and NewWorld crops such as maize, white potatoes, sweet potatoes, and manioc had not traveled east to Europe” [ CITATION Cro \l 1033 ]. Looking at the Americas amid this time, there were “no animals such as horses, cattle, sheep, or goats, all animals of Old-World origin”[ CITATION Cro \l 1033 ]. The New World did not possess any sort of domesticated animals associated with the Old World, nor did it have the pathogens associated with the Old World’s dense populations of humans and such associated creatures as chickens, cattle, black rats, and mosquitoes. Among these germs were those that carried smallpox, measles, chickenpox, influenza, malaria, and yellow fever.
