I just came across an article distributed by the Global Press Release Distribution about the above topic. This brought my thinking to the use of DNA in general, and about the ethics of cloning specifically.
Dan Vergano, USA TODAY. Scientists have cloned man’s best friend for the first time, creating a genetic duplicate of a 3-year-old male Afghan hound, South Korean scientists reported Wednesday
The puppy was born in April to its surrogate mom, a Labrador retriever. His name: Snuppy, short for Seoul National University puppy. The team of scientists there that cloned the dog, led by Hwang Woo Suk, is the same one that first cloned human embryonic stem cells last year. Their achievement is reported in the journal Nature. Researchers have cloned other animals, but dog cloning has posed a particular challenge. And the difficulties have alarmed some animal advocates and researchers.
There are benefits of cloning your pet according to the Seoul National University, but there are also many groups that are questioning the ethics involved in cloning.
