1997年2月英国科学家宣布,他们以无性繁殖的方法,培养出取名叫“多利”的绵羊,它是世界上第一只体细胞克隆动物。可以说它是生物学发展的一个里程碑,标志着生物科学发展的巨大突破。继“多利”之后,美国科学家报道,他们成功地利用克隆技术繁殖出两只恒河猴,这是人类首次利用克隆技术培养出与人类关系密切的物种。其实,我们的祖先很早就会用扦插法繁育果树,这就是最早的克隆。1968年印度科学家率
In February 1997, British scientists announced that they had cultivated a sheep named “Dolly” by means of asexual reproduction. It is the world’s first somatic cloned animal. It can be said that it is a milestone in the development of biology, marking a huge breakthrough in the development of biological sciences. Following the publication of “Dolly,” U.S. scientists reported that they successfully cloned two Rhesus macaques using cloning techniques. This is the first time humans have used cloning techniques to cultivate species closely related to humans. Actually, our ancestors would breed fruit trees with cuttings very early on, which is the earliest clone. 1968 Indian scientists rate
