Hi, are some animals more easily cloned than others? Is it easier to clone simple organisms? Also, I wanted to add information about Cloning and Stem Cell Technology to the article, as this is relevant to the ethics of the whole thing.

Stem cells are the master cells of the human body. They can divide to produce copies of themselves and/or into many other cells. They are found in various parts of the human body at every stage of development from embryo to adult. Stem cells taken from embryos that are just a few days old, can turn into any of the 300 different types of cells that make up the adult body. They are so versatile, they could potentially be used to repair and replace damaged human tissue. In future it is hoped that stem cells could be used to treat and cure a variety of diseases and injuries including Parkinson's disease, stroke and diabetes.

One of the key issues in the ethics of cloning is that that the embryo has the moral status of a person from the moment of conception. But stem cells may be harvested from the placenta after childbirth or spare human embryos left over from fertility treatments. So in that sense, they circumvent the ethics debate.
