The same team of Scottish scientists that created the Dolly sheep clone has begun working on inter-species skin grafting. Figuring that burn victims might be helped by receiving large grafts of skin from a compatible “donor” they’ve begun experiments to determine which creatures have compatible skin types. Since they’re already so familiar farm animals, they decided to conduct their first experiment by replacing a large portion of Dolly’s hide with the epidermis from a common donkey. Eager to gather more good publicity from this new venture, they released this information to the press in advance of the actual procedure. The newspaper reported it like this. “Ass skin ewe shall receive.”
