It started with Dolly

In 1996, Scottish researchers shocked the world with the news that they had cloned a sheep, which they dubbed Dolly. Due to progressive lung disease and arthritis uncommon for a sheep of her age, Dolly was euthanized at age 6. (Her taxidermied remains are displayed at The National Museum of Scotland, shown here.) Dolly’s birth and death sparked a debate about the ethics of animal cloning that continues today. Some see cloning as the only hope for certain, critically endangered species. Here’s a look at some of the lesser-known animals created through cloning. (Text: Katherine Butler)
