In 1928, Arkansas state passed a law by referendum making it illegal to teach "the theory or doctrine that mankind ascended or descended from a lower order of animals." In 1999, the Board of Education of Kansas State in the United States voted in favour of removing any reference to evolution from its science curriculum. It seems that there has been a raging debate in parts of America in the last century about the theory of evolution. After reading multitudes of web pages, the question that still occurs to me is - why do people worry so much about this issue?
