The only way to understand what your professor wants is to contact him or her. Perhaps you could do so by email. In the mean time try going on google scholar and typing in specific topics about cloning such as ethical issues of cloning and/or positives to cloning, etc. One is negative and one is positive, so you can contrast the two. Make sure they are credible resources from a journal and not just some random website. Or, if you are at a college, you can go to the library and look in their database for journal and research articles for free. Sometimes colleges allow you to do this online. You need to figure out your thesis, which could be your stance on the topic. Make an outline of what you want to discuss on both sides of the issues and develop on that by including citations from the articles and your own thoughts.

I cant help with the entire question but try to use recent events or articles on cloning. The articles should give details on what they are trying to do with it and it may hint some good details and facts. I dont know any links but I know that there are websites that have old articles on those subjects. Try a local library they may have something you need. Try websites like these http://auth.proquestk12.com/IA/ they can give some information on both sides of the topics.

good resourses for college is journals. they are more current than books and more accurate than a lot of sights online. the best way to find journals… which are researches done by professionals… is by going to your school library online and go to the journal section… type in animal cloning and there will be hundreds or thousandz of journal articles on that topic.

just by reading the journal title, you will know if the person doing the study or research is for or against cloning…. you should have no problem finding articles for or against….

oh yeah… make sure you get journals and not magazine articles… it does make a difference.
