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

The groundbreaking research injecting 25 human cells into the embryos of long-tailed macaque monkeys. The human cells inside 132 of the embryos. The scientists the development of the embryos for 19 days. Many people are disturbed by the research and believe it to the realm of horror movies. Professor Greely said he that there are many ethical concerns around the creation and use of chimera.
