Today we are writing about animal cloning.

What is Cloning?

Human cloning is illegal but animal cloning is not. Cloning makes
an identical copy of an animal, plant or even a human (even
though this is illegal). Cloning started in the 1960’s. A frog was
the first animal to be cloned. About 98% of cloning fails. Some
clones appear naturally for example identical twins they look
the exact same, but they have not been cloned.




How do you clone?

Lots of animals have been cloned before but one of the most
famous animals to be cloned was a sheep named Dolly. She is
famous because she was made from adult sheep cells.




To clone you take donor cells from two of the same animals
(one male and one female) and then take and discard the
nucleus from the egg cell. Move the somatic cell nucleus into
the enucleated egg cell. Stimulate cell division. Place the
embryo into the pregnant mother. It costs $20,000.
What has been cloned?

These are some animals that have been cloned:
Tadpole (1952)
Carp (1963)
Dolly the Sheep (1996)
Rhesus monkey (2000)
Cattle (2001)
Cat (2001)
Mule (2003)
Horse (2003)




What people think about cloning?

In February 1997 a survey was taken among 1005 American
adults. This is what they thought:

93% felt that cloning humans is a bad idea.
7% thought that it was a good idea.

66% felt that animal cloning was a good idea.
34% thought that it was a bad idea.

69% are scared of cloning humans.
31% are not scared of human cloning.

74% believe that human cloning is against Gods will.
26% believe that human cloning is not against Gods will.

There is a lot of debate about cloning. People who disagree
about cloning think that things that have been cloned have
health problems but people that agree with cloning think that
they are just the same as any other animal.

Scientists think that cloning is good because it means there is
more medicines, food and less animals will be endangered.
Fewer animals will be endangered because if they clone the
animals then there will be more of them. There will be more
food because there will be more animals to get meat from.



Endangered animals.

American scientists have revealed the birth and the death of
the first endangered animal to be cloned. It was a baby bull
gaur named Noah. He was born on the 18 February, but he
died 2 days after he was born. He died of a common dysentery
(disease). Researchers found out that the problem was not
anything to do with the cloning procedure.




Cloning gone wrong.

Obviously the cloning of Noah went wrong but he is not the
only one. A couple of other animals that have been cloned have
gone wrong as well. When the frog was cloned it was inside out
(so its outsides were on the inside of him and his insides were
on the outsides of him). Some people believe that this was not
cloning, but others believe that it was all down to cloning.
Why clone animals when you can breed for free?




Another debate is that why do people want to clone if they can
breed animals for free instead of wasting $20,000.
Breeding is free and is natural but cloning may clone an exact
copy of animals but WHY? Some people want to clone because
their pets or family have diseases and will die but they would
don’t want them to die so they still want them in their lives.
Also scientists are trying to clone extinct animals and
endangered animals.


Conclusion?

Scientists believe that some cloning is right but other cloning
is wrong like human cloning. We believe that cloning is good if it
is perfected so the endangered animals live and don’t die
because it has not been done properly.
