Numerous animals have been cloned, starting with frogs in the 1950s, followed by the landmark birth of Dolly the sheep in 1996. Since then, various mammals have been cloned from adult somatic cells, including cats, dogs, pigs, cattle, horses, sheep, goats, mice, rats, rabbits, deer, mules, and endangered species like the black-footed ferret and Gaur.

What animals have been genetically cloned?

Since 1996, when Dolly was born, other sheep have been cloned from adult cells, as have mice, rabbits, horses and donkeys, pigs, goats and cattle. In 2004 a mouse was cloned using a nucleus from an olfactory neuron, showing that the donor nucleus can come from a tissue of the body that does not normally divide.

Is Dolly the cloned sheep still alive?

On February 14, 2003, Dolly was euthanized by veterinarians after being found to suffer from progressive lung disease. Her body was preserved and displayed at the National Museum of Scotland in Edinburgh.

Have extinct animals been cloned?

An animal like the thylacine that died out almost a hundred years ago simply couldn't be brought back this way. But it could be an option for recently extinct species. In 2003, researchers successfully cloned a Pyrenean ibex, a type of goat that went extinct when the last living individual was killed by a falling tree.

Is Tom Brady's dog actually a clone?

Yes, Tom Brady confirmed in November 2025 that his current dog, Junie, is a clone of his late pit bull mix, Lua, who died in 2023, using non-invasive DNA technology from a blood sample. Brady worked with Colossal Biosciences, a company he invests in, to create the clone, which gives his family a "second chance" with a genetic twin of their beloved pet, though personality and experiences will differ.
 

10 Animals That Have Been Successfully Cloned by Scientists

What animal was brought back from extinction 2025?

In April 2025, Colossal Biosciences showcased three genetically modified wolf pups with the characteristics of the dire wolf: six-month-old males Romulus and Remus and two-month-old female Khaleesi.

When was the first person cloned?

On Friday, December 27, 2002, Boisselier, a Raëlian bishop and CEO of Clonaid, announced at a press conference in Hollywood, Florida that Clonaid had successfully performed the first human reproductive cloning.

Why was Dolly euthanized?

Death. On 14 February 2003, Dolly was euthanised because she had a progressive lung disease and severe arthritis. A Finn Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived 6.5 years.

Is cloning still being done?

Therapeutic cloning would involve cloning cells from a human for use in medicine and transplants. It is an active area of research, and is in medical practice over the world.

Who was the first person to clone himself?

The first man to clone himself (create a genetic copy) was American scientist Dr. Samuel H. Wood in 2008, using his own skin cells to create cloned human embryos for stem cell research, a process called Somatic Cell Nuclear Transfer (SCNT), though he did not implant them to create a baby. 

Can human organs be cloned?

Potentially, it might be possible to clone organs by using SCNT to clone embryos, extracting the stem cells, and stimulating the stem cells to differentiate into the desired organ, but this will require more research.

How long did Dolly live after being cloned?

Dolly. The world's first cloned mammal has gone on to greener pastures. Dolly the sheep, the first mammal cloned from an adult cell, died on 14 February. Her caretakers at the Roslin Institute in Scotland euthanized the 6-year-old sheep after diagnosing an incurable lung tumor.

Why can we clone animals but not people?

Since then, scientists have cloned cows, cats, deer, horses, and rabbits. They still have not cloned a human, though. In part, this is because it is difficult to produce a viable clone. In each attempt, there can be genetic mistakes that prevent the clone from surviving.

Who was the man who cloned himself?

In 2008, Wood created embryo copies of himself by placing his skin cells in a woman's egg, marking the first time anyone had done so with adult skin cells. The five cloned embryos were later destroyed.

How old is the oldest cloned animal?

A Finn Dorset sheep, cloned from a breast cell from an adult ewe, was born at Edinburgh's Roslin Institute (UK) in July 1996. Named after the singer Dolly Parton, she was mated naturally with a Welsh mountain ram at the end of 1997 and gave birth to her healthy lamb called Bonnie on 13 April 1998.

What countries allow human cloning?

In addition to the United Kingdom, China, South Korea, and Japan all have legislation allowing carefully regulated therapeutic cloning so would be unable to sign up to legislation banning all forms of cloning.

Which animal has only 10 left?

The animal with only about 10 individuals left in the world is the Vaquita, the world's rarest marine mammal, a tiny porpoise endemic to Mexico's Gulf of California, critically endangered primarily due to entanglement in illegal fishing gillnets.

What animal will not exist in 2050?

Here are four animals at risk of extinction by 2050.

Is the dire wolf still alive?

The dire wolf (Aenocyon dirus /aɪˈnɒkaɪ.ɒn ˈdaɪrəs/) is an extinct species of canine which was native to the Americas during the Late Pleistocene and Early Holocene epochs (125,000–10,000 years ago). The species was named in 1858, four years after the first specimen had been found.
