Scientists Create A Sheep That's 15% Human
The sheep will ultimately be used for organ transplants.
Implications - Scientists plan to make the process suitable for human transplant by extracting stem cells from the donor's bone marrow and implanting them in the peritoneum of a sheep fetus. Then, once the lamb is born, its liver, heart, lungs and brain would have enough human characteristics to make them suitable for transplanting. Oh, what a brave new world that has such wonders in it!
