The document discusses animal-human chimeras, which combine human and animal cells, tissues or DNA. Some examples given are rats with 1% human brain cells and pigs with human blood. While some scientists see potential medical benefits, others argue it is unethical and raises questions about how to classify such hybrids. The author believes more research could be acceptable only with new ethical guidelines to avoid unintended problems.

In ancient Greek mythology it was a combination of three animals in one body; in the modern age it’s the combination of human parts (DNA, cells, tissues, etc.) and animal parts in one body. Although considered unethical, inhumane and even dangerous by many (it has been banned in Canada); it is a practice that according to other scientist might hold the key for future medicines and treatments. Examples of modern chimeras include rats with 1% human brain (future experiments will try to increase that percent to 100), the fusion of human cells in rabbit eggs, pigs with circulating human blood, and human tissues inside animal bodies for surgical uses. Scientists are also using these chimeras to test drugs and medicinal procedures and treatments, so they can be later performed, if successful, in real humans. They believe that if animals have more human aspects and physiological traits they can better understand drugs and see more real-life reactions. Although it may seem perfect for medicinal uses, there are many concerns with this; starting with the simple fact that, how can that animal or chimera be classified, human or an animal? What kind of laws could help protect these chimeras? Many disasters can happen from this, starting with the fact that this is altering the course of natural selection, natural habitats, and animals and humans themselves. This is a relatively new phenomenon, but test are underway to keep extending this unknown field. In my personal opinion I believe, yes this can be very beneficial for medical, surgical, and scientific advancements, but there is no way this is ethical and safe. I would support this type of research and experimentation only if there are some newly drawn boundaries and ethical guidelines. As scientist we want to create solutions, not new problems.<br />Mott, Maryann. \"
