Cloning: a giant step

November 12, 2007

For the first time, scientists have created dozens of cloned embryos from adult primates. But what are the implications of this technical breakthrough for the future of mankind?

A technical breakthrough has enabled scientists to create for the first time dozens of cloned embryos from adult monkeys, raising the prospect of the same procedure being used to make cloned human embryos. Attempts to clone human embryos for research have been dogged by technical problems and controversies over fraudulent research and questionable ethics. But the new technique promises to revolutionise the efficiency by which scientists can turn human eggs into cloned embryos. . . .

The development will not be welcomed in all quarters. Opponents of cloning will argue that the new technique of manipulating primate eggs to improve cloning efficiency will lead to increased attempts at creating – and destroying – cloned human embryos for research purposes. (The Independent)
