Cloning v De-extinction.

 ]What Is Cloning?

Cloning is when you take a human or animal’s DNA to make a replica/twin/copy. There are five steps in the cloning process.

  1. Firstly you have to get DNA from an animal - this could be from a blood sample, saliva, or urine

  2. then the next step is to study the DNA (finding the genome sequence), 

  3. Next is to fill in the gaps using DNA from a similar animal (E.g. for a moa, you would use emu or ostrich DNA), 

  4. 4th is to create an embryo and find a  Surrogate Mother for the clone. 

  5. The last step is to wait for the clone to be born.

Examples of cloning

If you didn't know, you can make a clone/twin without using anything, it‘s called Natural Cloning, Natural Cloning is when you get your parents cell and it gets split in half and makes a lot of copies that make you look like your identical twin, Fun fact - as many times as the cell splits that's how many twins that will be created, but getting a identical twin is very rare to get.

The very first cloned mammal was Dolly the sheep who was cloned in 1996 July 5 and died in 2003 it only lived for 6 years and was cloned in Scotland. Cloning is kind of the same thing as de-extinction but cloning is when you take DNA from a living organism and de-extinction is when you get DNA from extinct animal fossils.


What Is De-Extincion

In the school journal, page 12,  Return Of The Moa? by Quinn Berentson, it was talking about extinct animals that can be de-extinct, for example, Moa, Wooly Mammoth, Huia, Tasmanian Tiger and many others, but what are the reasons why? The reason why is because it could fix the mistake that they have made in the past, bring happiness to the world, also when you bring them back you get to have a closer look at the moa. But there are some animals that can’t be de-extinct because the fossils are too old. For example, Dinosaurs. their bones don't have enough DNA. Now i am going to talk about what are the bad things about de-extinction? de-extinction is a total waste of money and we should spend the money on endangered species that actually need it for their habitats, and once scientists de-extinct an animal they wouldn't know the reaction the animal/creature will have.




What is the purpose of cloning?

The purpose of cloning is to clone animals for experiments to prevent disease from spreading or viruses such as Covid-19 and many other viruses that may come in the future. 


Who created cloning?

The very first study of cloning took place in 1885 by a German scientist-Hans Adolf Eduard Driesch, he began reaching and then in 1902 he was able to create 2 twin salamanders by dividing the embryo into half.


Is cloning ethical?

Before I get on with the question. What is ethical? Ethical is when you answer a question and there aren't any right or wrong. This means we should think about if we really should do cloning or not - doesn’t that mean we are playing God? Should we have that power? Should we just let nature take its course? This is the ethical dilemma.
