History
After Dolly the sheep was cloned in 1996, scientists had managed to clone numerous other animals, including cats, cows, gaur, horses, mice, mules, pigs, rabbits and rats but had been unable to successfully clone a dog due to the problematic task of maturing a canine ovum in an artificial environment. After several failed attempts by other scientists, Woo-Suk Hwang, a professor of Seoul National University, and a team of other scientists were able to successfully create a clone using tissue from the ear of a 3-year-old Afghan hound. 123 surrogate mothers were used to carry the embryos, of which 1,095 were implanted, the procedure resulted in only three pregnancies; one resulted in a miscarriage, the other pup was born successfully but died of pneumonia three weeks after birth, the successful clone was carried by a Labrador Retriever. From the original 1,095 embryos to the final two puppies, this placed the success rate of the project at less than two tenths of a percent. Snuppy was named as a portmanteau of the initials of the Seoul National University (SNU) and the word "puppy".

Famous quotes containing the word history:
“We don’t know when our name came into being or how some distant ancestor acquired it. We don’t understand our name at all, we don’t know its history and yet we bear it with exalted fidelity, we merge with it, we like it, we are ridiculously proud of it as if we had thought it up ourselves in a moment of brilliant inspiration.”
—Milan Kundera (b. 1929)
“Let it suffice that in the light of these two facts, namely, that the mind is One, and that nature is its correlative, history is to be read and written.”
—Ralph Waldo Emerson (1803–1882)
“The thing that struck me forcefully was the feeling of great age about the place. Standing on that old parade ground, which is now a cricket field, I could feel the dead generations crowding me. Here was the oldest settlement of freedmen in the Western world, no doubt. Men who had thrown off the bands of slavery by their own courage and ingenuity. The courage and daring of the Maroons strike like a purple beam across the history of Jamaica.”
—Zora Neale Hurston (1891–1960)
