Which type of animal was the first to be successfully cloned in 1997?
Answer: Dolly the sheep made history in 1997, when the scientists who created her announced she was the first cloned mammal to survive.
Scientists created Dolly in a test tube, after they figured out how to take a sheep egg cell, remove its DNA, and replace it with DNA extracted from a different sheep’s skin cell. The newly fused cell was then implanted into a surrogate mother sheep, who gave birth to Dolly on July 5, 1996. Because Dolly’s DNA came from a mammary gland cell, she was named after the country singer Dolly Parton.
The sheep is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Wikipedia
