While many would agree that using DNA as evidence is a good idea, manipulating human genetics is another issue. Cloning has surfaced as a debate with moral and ethical implications. Sheep have been cloned. One rationale for cloning animals was to provide more food to starving nations. Is cloning safe? Is creating a replica of an animal ethical? What are the long term effects of cloning?

Many people wonder if cloning humans will come next. Will it be a like a horrible old science fiction movie? How does the cloning process occur? How do scientists and doctors create a clone?

Stem cell research is also an issue discussed on many political shows and at dinner parties around the country. Is stem cell research ethical? When does life technically begin? Stem cell research can help to save a great number of people suffering from disease, but at what cost?
