Nevertheless, in October 1492 when Christopher Columbus together with his team docked in the Bahamas, the two long-separated worlds: Afro-Eurasia and the Americas were rejoined. Together with the various voyages that ensued, Christopher Columbus’ voyage led to a great disruption of much of the biological separation that the continental drift caused. Following Christopher Columbus’ arrival in the Americas, these two worlds’ plant, animal, as well as bacterial life started mixing. This process is known as the Columbian Exchange. It reunited formerly biologically distinct landmasses and had lasting and dramatic impacts on the world (McNeill 1&2). This paper describes the Columbian exchange in its four aspects namely biological, demographic, cultural and economic aspects as well as its impacts on Europe, Asia, the New World and Africa.
For a long time, the prevailing pattern of biological growth on the globe has been one of geographical variation dictated by the clear fact of the separateness of continents. Rather than identical, organisms have had the tendency of becoming more dissimilar, even in the Amazon, Congo basins among others where climates have been similar. This is owing to the fact that they had little or no contact with one another. People have gone to and lived, or at least spent time the world over. They always carry with them their weeds as well as disease organisms unintentionally, and their crops and domesticated animals knowingly. Because of this, humans have overturned, in the very most recent tick of time, the ancient trend of geographical bio-diversification.
The Columbian Exchange was appreciably an extensive swap of fauna, flora, transmissible diseases, customs and ideas between the Western and Eastern hemispheres. It was, in the entire human history, one of the most important events with reference to traditions, the natural environment and farming. Christopher Columbus, who was the first to take a voyage to the Americas in
