By injecting human cells into the fetus of a sheep, scientists have created a sheep that's 15% human. To the chagrin of human-animal hybrid fans, the sheep does not have human features.
Scientists have created the world's first human-sheep chimera – which has the body of a sheep and half-human organs.
The sheep have 15 per cent human cells and 85 per cent animal cells – and their evolution brings the prospect of animal organs being transplanted into humans one step closer.

Animal rights activists fear that if the cells get mixed together, they could end up with cellular fusion, creating a hybrid which would have the features and characteristics of both man and sheep. But Prof Zanjani said: "Transplanting the cells into foetal sheep at this early stage does not result in fusion at all."
