â€œScientists have created the world’s first human-sheep chimera - which has the body of a sheep and half-human organs.
The sheep have 15 percent human cells and 85 percent animal cells - and their evolution brings the prospect of animal organs being transplanted into humans one step closer.
Professor Esmail Zanjani, of the University of Nevada, has spent seven years and Â£5million perfecting the technique, which involves injecting adult human cells into a sheep’s foetus
But the development is likely to revive criticisms about scientists playing God, with the possibility of silent viruses, which are harmless in animals, being introduced into the human race.
Dr Patrick Dixon, an international lecturer on biological trends, warned: “Many silent viruses could create a biological nightmare in humans. Mutant animal viruses are a real threat, as we have seen with HIV.”
If this story is trueâ€¦Iâ€™m not sure if I like where this is goingâ€¦the opening of a â€œPandora’s boxâ€ perhapsâ€¦
I understand the â€œgoalâ€ is having organs to harvest for the purpose of prolonging human life, but something about this seems warped.
