This discovery caught the attention of the Western European leaders. Soon‚ these leaders prompted their own explorers to start their own expeditions. Although we can consider Columbus’s first discovery of the New World as an “encounter”‚ we cannot apply this term to the later discoveries because the word “conquer” would be more fitting. The Native Americans and Africans had varied responses to European colonization. The term “encounter” is only appropriate for Columbus’s first discovery. At the

What are the implications of personal genomes for drug discovery and development ? In the past decade‚ increasing amounts of dollars have been spent on drug development yet the amount of new drugs entering the market per year remains the same. Furthermore with 200 billion dollars of patents expiring in the past four years (Witty‚ 2010)‚ innovative pharmaceutical companies will need to look at new approaches to discover drugs. With the human genome being sequenced in 2003‚ a new field of science
