LONDON - British scientists say they have created human embryos containing DNA from two women and a man in a procedure that researchers hope might be used one day to produce embryos free of inherited diseases...

The process aims to create healthy embryos for couples to avoid passing on genes carrying diseases.

The genes being replaced are the mitochondria, a cell's energy source, which are contained outside the nucleus in a normal female egg. Mistakes in the mitochondria's genetic code can result in serious diseases like muscular dystrophy, epilepsy, strokes and mental retardation.

此科研成果显示了三个父母亲 （两个生母）的可能性。感想：先进的科学令人相信世界上几乎没有什么事情是不可以被人创造出来的。。。因而当有预言家预示将来人类的寿命会被延伸至一千岁时，需要慎重的思考一下再决定是否可以说“no“。。。
