What extinct animals are coming back?

While no fully extinct animal has been successfully brought back to thrive in the wild yet, major efforts are underway for "de-extinction," with projects aiming to resurrect the woolly mammoth, Tasmanian tiger (thylacine), dodo, and passenger pigeon using advanced genetics, while species like the European bison and mountain gorilla have already made significant comebacks from the brink due to conservation. Companies like Colossal Biosciences are using gene editing to create mammoth-like elephants and resurrected dire wolves, while other projects focus on back-breeding to revive ancient species like the aurochs.

Are any extinct animals coming back?

Yes, some extinct animals are making comebacks through dedicated conservation or "de-extinction" efforts, with recent successes including the resurrection of the dire wolf (via cloning/gene editing) and the Eastern barred bandicoot (from near-extinction), while projects for the woolly mammoth and dodo are actively underway, but true, full "bringing back" is complex, often creating proxies like the aurochs. 

What extinct animal to bring back?

While true "comebacks" are rare, scientists are actively working on de-extinction projects for animals like the Dire Wolf, Woolly Mammoth, and Thylacine using gene editing, with a biotech firm claiming to have brought back the Dire Wolf as a functional copy (a hybrid with gray wolves) in 2025, but these are creating functional proxies, not identical species, while other projects like the Aurochs use 'back-breeding' to recreate ancestral traits in cattle for rewilding.
 

What extinct animals are coming back in 2025 in the USA?

In April 2025, scientists announced the birth of three "dire wolf" pups thanks to genetic engineering. Dire wolves (Aenocyon dirus) lived during the last ice age (2.6 million to 11,700 years ago) and went extinct more than 10,000 years ago.

Which animals are making a comeback?

Scientists are actively working on bringing back animals like the Woolly Mammoth, Dodo, Thylacine (Tasmanian Tiger), and Dire Wolf through "de-extinction" using gene editing, while also reintroducing nearly extinct species like black-footed ferrets and bison to restore ecosystems, aiming to reverse human impact and enhance biodiversity.
 

7 Extinct Animals That Could Actually Come Back

What 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 found only in Mexico's Gulf of California, critically endangered primarily by illegal gillnet fishing. Despite being the smallest porpoise, they are often caught and drowned as bycatch in nets meant for other species, pushing them to the brink of extinction.
 

What animal is coming back in 2027?

The animal making headlines for a planned 2027 "comeback" is the Woolly Mammoth, thanks to Colossal Biosciences, a company using gene-editing (CRISPR) to create a cold-resistant elephant hybrid with mammoth traits, aiming to reintroduce it to the Arctic to combat climate change.
 

What animals will not exist in 2050?

By 2050, numerous iconic species face extreme extinction risk, including Amur Leopards, Sumatran Orangutans, Black Rhinos, Sumatran Elephants, Saola, Vaquitas, Polar Bears, and Lions, primarily due to habitat loss (deforestation, climate change), poaching, pollution, and human conflict, with some already functionally extinct or with extremely low numbers, though conservation efforts offer hope for some populations. 

Do we have dire wolves now?

No, dire wolves ( Aenocyon dirus) are still extinct, having vanished around 12,000-13,000 years ago, but a biotech company, Colossal Biosciences, has recently used gene-editing to create pups with dire wolf-like traits by modifying grey wolves, leading to news headlines about "de-extinction" that scientists clarify are genetically-edited grey wolves, not true resurrected dire wolves.
 

Can DNA bring back extinct animals?

In the last decade, laboratory initiatives to recreate long-extinct species have stirred controversy. Now, scientists increasingly agree “de-extinction” is not possible, but breeding living animals with genes similar to those lost species can be a useful conservation tool.

What animal has only 100 left?

The Amur leopard is one of the rarest big cats in the world, with only around 100 individuals left in the wild.

What animal got extinct twice?

However, she died several minutes after birth of a lung defect. The Pyrenean ibex is the first animal to have been brought back from extinction through cloning and also the only one to become extinct twice.

Can dinosaurs be revived?

No, dinosaurs cannot come back in the way shown in movies like Jurassic Park because their DNA has degraded too much over 66 million years to be retrieved and reconstructed; scientists can't clone them from fossils. While some efforts focus on "de-extinction" for much younger species like woolly mammoths, recreating dinosaurs is scientifically impossible due to the lack of viable genetic material, and even if possible, the modern environment, with different atmospheric conditions and plants, would pose immense survival challenges for them.
 

Could megalodon be brought back?

No, bringing back the megalodon is currently impossible because we lack viable DNA, and even if we could genetically engineer a giant shark, resurrecting a species that died out millions of years ago presents immense ethical and ecological challenges, as it would struggle to survive in today's altered marine environments and could disrupt modern ecosystems. Scientists have found no evidence of megalodons surviving in the deep ocean, dispelling myths of their continued existence. 

Are we in a 6th extinction?

Yes, most scientists agree we are either entering or in the midst of the Sixth Mass Extinction, driven by human activities like habitat destruction, climate change, and pollution, with species disappearing at rates hundreds to thousands of times faster than the natural background rate, threatening ecosystems vital for human survival. While some debate the exact timing or metrics, the consensus points to unprecedented biodiversity loss caused by humanity, the first such event driven by a single species, making urgent conservation crucial. 

What is the #1 rarest animal in the world?

There isn't one single "rarest" animal, as it depends on how you measure it (population size, restricted range, function extinction), but the Vaquita (marine mammal) and Northern White Rhino (land mammal) are often cited as the most critically endangered with extremely low numbers, alongside elusive species like the Saola, with potentially only a handful left and rarely seen. The Vaquita has fewer than 10 individuals left, while the Northern White Rhino is functionally extinct with only two females remaining, relying on assisted reproduction.
 

Are dogs 98% wolf?

Similarities Between Dogs and Wolves

After all, the two species descend from a common ancestor. In fact the two species share 98.8% of the same DNA. They can even interbreed (although their offspring are typically not fertile). Dogs of similar size to a wolf share a similar life expectancy (12-14 years in captivity).

How rare is red wolf?

In 1973, the red wolf became one of the first species added to the Endangered Species Act. Their population has fluctuated since then, rarely exceeding 100. In recent years, it's dropped dramatically, to the current estimate of just 28 wolves.

What direwolf is still alive?

Ghost, adopted by Jon. One of the only surviving direwolves.

Which animal could live forever?

The immortal jellyfish (Turritopsis dohrnii) is the only animal known to be "biologically immortal" because it can reverse its life cycle, reverting to a juvenile polyp stage when stressed or damaged, potentially repeating this indefinitely and cheating death from old age, though predators and disease still affect them. Other exceptionally long-lived animals include glass sponges (over 10,000 years) and Greenland sharks (500+ years), but they don't reverse aging like the jellyfish. 

How can we stop extinction?

Preventing extinction involves large-scale conservation, strong laws like the Endangered Species Act (ESA) to protect critical habitats and species, and individual actions like reducing consumption, buying sustainable products, recycling, creating wildlife-friendly yards, and supporting conservation organizations, all aimed at reducing habitat loss, pollution, and illegal wildlife trade.
 

What animal has only two left in the world in 2025?

The Northern White rhino is on the brink of extinction. In the chart, you can see the collapse of this beautiful animal's population as a result of poaching, habitat loss, and conflict. Now, only two individuals are left — Najin and her daughter, Fatu.

Which animal has only 10 left?

The animal with only about 10 individuals left is the vaquita, the world's rarest marine mammal, a tiny porpoise found only in Mexico's Gulf of California, critically endangered primarily by getting caught in illegal fishing gillnets. Despite being the most endangered cetacean, conservationists are working to save them, as even a few surviving individuals show signs of reproduction.
 

Could we clone a mammoth?

"Because species like the woolly mammoth died 4000 years ago, we have fragments of its genome because we find woolly mammoth specimens frozen in the ice. But because these specimens are so old, their DNA isn't great, their DNA is too degraded for us to use for cloning."

What animal was brought back to life?

Scientists, primarily through the company Colossal Biosciences, have brought back a functional version of the extinct dire wolf (Aenocyon dirus), a large canid from the Ice Age, by genetically engineering gray wolves and domestic dogs to express dire wolf traits, creating pups named Romulus, Remus, and Khaleesi, though they are not pure dire wolves but rather de-extincted hybrids. They also created "woolly mice" as a step toward de-extincting the woolly mammoth and are working on the dodo and Tasmanian tiger (thylacine).
