Cloning of endangered animals and species

Cloning of endangered animals and species

A research group from Scotland presented a groundbreaking scientific finding 25 years ago in a stable at the Roslin Institute outside Edinburgh.

After searching for animal cloning for a long time, researchers found that with the help of body cells from an adult individual, they can clone a mammal. In this case, Dolly the sheep was born to her surrogate mother. Dolly herself died in 2003, and since then she has had a total of six successors with exact genetic copies.

Ultimate guide

Professor Emeritus at the University of Copenhagen, Paul Hettel, conducted research on animal cloning and confirmed that Dolly was a major advance.

Dolly was the ultimate proof that we can now pull cells out of the body, grow them and use them for cloning afterward. It opened up many opportunities, Hyttel tells Danish DR.

new era

Dolly’s cloning was the beginning of a new era in research. Among other things, researchers have used technology to develop medicine and genetic technology. The new knowledge also opened up to more empirical research.

According to Henrik Calliesen, a professor at Aarhus University, cloning can be used to save endangered species. Likewise, technology can be beneficial to very valuable animals.

– In Korea, they cloned dogs and they are especially good at sniffing drugs at the airport. In Dubai, the Arabian camel has also been cloned. A good camel can be worth millions of dollars, says Callison.

Broadway star Barbra Streisand has paid a heavy price to clone her dog, which she lost after 14 years.

In a column in the New York Times, she wrote that she handled the loss of a dog better by taking part of her DNA with her. Then she cloned two dogs.

Many companies in some countries offer animal cloning. The Council on Biotechnology draws our attention to the fact that for every successful animal cloning, there are also many failed attempts where clones are born with deformities or die before birth.

On the other hand, it is fortunate that cloning occurs naturally, including when creating identical twins. They emphasized that for researchers, cloning is effective in developing new treatments for diseases.
