Assessment #4 Major Essay is an 1800 word essay, worth 25% of your assessment marks. Choose one of the following topics: Topic A: The origin of life on Earth (How did the first biological molecules, the first replicators or the first cells arise?) Topic B: The risks from emerging diseases (Why do new diseases keep appearing, where do these come from, and how might human behaviours drive this?) Topic C: The molecular basis of cancer (What happens to DNA and to cells that leads to the uncontrolled cell growth that we know as various forms of cancer?) The major essay is designed to build on the skills you acquired in the reference list assignment. In the essay, you will be tested on finding relevant scientific literature, understanding its content and arguments, and restating that information in your own words. So choose a topic that interests you, and talk about it with me, your tutors or with your fellow students before you begin. You will need to carefully plan the essay, since fitting these complex topics into the 1800 word limit will be difficult. A word of warning: Plagiarism (copying material without alteration) will not be tolerated and will result in a mark of zero for the essay. The essay should be typewritten and double spaced. It should not be more than 1800 words long (plus or minus 10%). At least fifteen references should be consulted, and these should be from reputable scientific sources. References should not be from Web Sites, since the quality and accuracy of Internet sources is extremely variable. Internet sources have not undergone peer review, and often contain misunderstandings, biased viewpoints or outright lies. The minimum standard for the references you use is that they should have an identifiable Author and date of publication. The references you can consult could include textbooks, edited books or scientific journals. Copies of papers can be downloaded from the internet databases, but in each case, these should have an identifiable author and a date of publication
