[Insert "That sheep's a damned liar!" joke here]

The (U.K.) Daily Mail recently reported that Professor Esmail Zanjani, of the University of Nevada, has created the world's first human-sheep chimera, having 15 percent human cells and 85 percent sheep cells. The research is aimed at eventually being able to create sheep organs capable of being transplanted into human patients. The hoped for process is described as follows:

The process would involve extracting stem cells from the donor's bone marrow and injecting them into the peritoneum of a sheep's foetus. When the lamb is born, two months later, it would have a liver, heart, lungs and brain that are partly human and available for transplant.

Excuse me, but... the brain?
