 Aldous Leonard Huxley

(26 July 1894 – 22 November 1963)

was an English writer and philosopher.

One of his famous novel is Brave New World. This novel written in 1931.

“ These,” he waved his hand , “are the incubators”.

“ Millions of identical twins. The principle of mass production at last applied to biology”.

Look at these mixed words and give the definition of what cloning is

identical is the their organisms creation to artificial of Cloning genetically parents

Cloning (from the Greek. clon – branch, shoot, Scion) is an artificial creation of organisms genetically identical to their parents.

You might not believe it, but there are human clones among us right now. They weren't made in a lab, though: they're identical twins, created naturally. 

Cloning is the creation of an organism that is an exact genetic copy of another

• Is it true that…
• identical twins are actually clones?
• clones have identical DNA?
• the word “clone” comes from Latin?
• “ clone” from Latin means brother?
• the embryos of mice were first cloned in Russia?
• a sheep was the first mammal cloned from an adult cell?
• Dolly, the sheep, was the first cloned in England?
• Cloned animals live longer that normal animals?

• Does Mother Nature know best? Cloning - using genetic engineering to make exact copies of living plants and animals - has been in science fiction for years. Since 1997, with the cloning of a sheep, Dolly, it has become part of real life and the subject of public debate. For some people, human cloning is acceptable in medicine 1________ the criticism that it is unnatural. For example, human tissue can be cloned for use in organ replacement or gene therapy. Also, organs provided by human clones could be 100% donor compatible 2________ organs provided in other ways might not be as successful. Moreover, couples who can't have children might be able to clone a child from themselves. Finally, endangered animals could be cloned to increase their numbers. 3__________, there are many arguments against cloning. 4 __________many people saw the cloning of Dolly as a major breakthrough, now they have to face the fact that the sheep is no longer alive. Thus, 5________ what some say, scientists have no idea of the long-term effects of genetic engineering. A growing number of genetically created creatures might be acceptable to society; 6_________ , creating 'perfect' plants and animals could eliminate the great variety of natural species on our planet. Furthermore, 7________ organs from cloned animals could be transplanted into humans, the risks to health are enormous, and some people find the idea repulsive. All things considered, I am against cloning. It is clear to me that we need to regulate genetic engineering and stop experiments now, before it is too late!

• Write down 5-minutes essay

” How would you feel if you found out you were nothing, but a clone created in science lab? Would you like to clone yourself ?”

• Write your argumentative essay “To clone or not to clone?”

What do you think

• Do the negatives outweigh the positives?
• Should cloning be allowed or prohibited?
• If it were allowed, could we regulate the process properly?

• Let’s remember how to write an argumentative essay. 1. Don’t forget to give the basic outline of your argument in the first paragraph. 2. One paragraph should be about arguments in favour of the statement. 3. Another paragraph should contain arguments against the statement. 4. Your conclusion should be a balanced summary taking both sides into account.
