According to Taiwan ettv news reports, copy the sheep Dolly has been the 10th anniversary of the birth, this period scientists successfully copied out of the 10 kinds of mammals, and even copy the human experiment also outgoing after eight times failed. Scientists said that when they are aware replication process, the more we understand that you want to copy the complete without defects of an animal is still some distance away.
Dolly, the world's first cloned sheep, shocked the world 1996 was born, also makes biological replication technology used in saving human life. But after six and a half years since lung cancer deaths, Dolly is only half the normal life of sheep, suddenly prove that so-called landmark replication technology is not omnipotent.
United Kingdom Kingston University mingjie Professor that "almost all replication animals have some growth anomaly, the efficiency is very low, many in the womb is dead, but many abortion death. ”
Even if successfully grown up, copy the animal or appear many health problems, but scientists are still hard to copy out now have cats, dogs, donkeys, 10 kinds of animals.
Mingjie noted, "we almost copies all of the species, other than primates (human), to the current date proof copy humanity is not possible. "However, in the tenth anniversary of the birth of Dolly the sheep, the scientific community news noted that already have scientists are studying the replication of human, current experimental have failed up to eight times.
