Cloning

Duh duh duh duh dada duh dada. Da da da duh dada duh dada. Noooooo (in case you didn't get it it was Darth Vader's song). Cheesy intro. I'm turning into someone else I know. "Cough" Scientific Waffle "cough".
Back on topic. Clones are exact copies of a living thing. By a copy I mean they have the exact same DNA. In the early 1900s scientists started experimenting by splliting animal embryos. Cloning an adult animal was a recent affair, though. In 1996 scientists in Scotland managed to clone a sheep named Dolly. Unfortunately Dolly died at a very young age and developed arthritis early. How do scientists clone, you ask. They remove DNA from one cell nucleus, copied then injected into another.

Dolly wasn't the only one cloned. Here's a list: Carp, sheep, mouse, cows, goats, pigs, rabbit, cat, horse, deer, ferrets, buffalo, dogs and wolfs and a lot more. However some scientists invented de-extinction. WHAAAAT!!! On July 30, 2003, a team of Spanish and French scientists reversed time. They brought an animal back from extinction. That animal was a kind of wild goat known as a bucardo, or Pyrenean ibex. Scientists in Japan said they could bring a wooly mammoth back by 2016.

Cloning a person is a big debate in the scientific community. One disadvantage is what happened to Dolly. The clone could die early and catch diseases. Another bad thing is genetic diversity. As I said in one of my previous blogs mutations can be helpful. Mutations can be immune to disease. Since clones all have the same genes they cannot be immune. There is still a big ethical question. Some people say only god should have the right to create lifeforms. What do you think is the right thing to do?
