In this rapidly changing world, we are seeing more examples of science fiction becoming science fact. team of American and Chinese scientists has created world's first part-human, part-monkey embryo. This fusion of genetic tissue is called chimera. scientists say it potentially paves way for lifesaving medical advances. Bio-scientist Henry Greely explained importance of this scientific breakthrough. He said: "The long-term goal of this research team is to grow human organs in pigs - kidneys, livers, hearts, etc." He added: "They want to do that to make more human organs for transplants. Tens of thousands of people on transplant list die every year waiting for transplant."

groundbreaking research involved injecting 25 human cells into embryos of long-tailed macaque monkeys. human cells developed inside 132 of embryos. The scientists studied the development of embryos for 19 days. Many people are disturbed by research and believe it belongs to realm of horror movies. Professor Greely said he appreciated that there are many ethical concerns around creation and use of chimera. He said: "Every time person gets organ transplant, the result is an intra-species chimera - organism made up of cells from two members of the same species....When human gets pig heart valve, she becomes inter-species chimera."
