last November, Iman, the last Sumatran rhino in Malaysia is death. Scientists malay contemplating using the technique of cloning, using tissue and cells of Iman and other rhinos who are deceased, in order to give birth to babies with the aim of developing this species as critically endangered on the entire planet, says CNN.

Only 80 Sumatran rhino still life
stem cells can become an embryo that could be implanted in a surrogate mother. But the chances of success are not guaranteed : the fertilization might fail, or the pregnancy, once the embryo is implanted. Scientists can also use the technique of somatic cell nuclear transfer (SCNT), which had been used to clone Dolly the sheep in 1996. It takes a nucleus from an adult cell (except sperm or egg) with its DNA in order to implant it in an egg that was not fertilized from which the nucleus has been removed. The techniques are all studied by scientists. Only 80 Sumatran rhino would be in life.

The Sumatran rhino are the smallest species of rhinoceros in the world. They are listed among the species in danger of extinction by the World Wildlife Fund. The International Rhino Foundation estimates that there are less than 80 still alive in the world, between Indonesia and Thailand. The population decline was initially caused by poaching for their horns, which were coveted as an ingredient of traditional asian medicine. Later, the overpopulation, the human has encroached on the natural habitat of the rhino, preventing them to gather and reproduce. There are only five species of rhino in the world, and all are threatened. Some sub-species have already gone extinct such as the black rhino of the West, a native of West Africa.Updated Date: 14 August 2020, 10:33
