Extinct Animals That May Still Be Alive

The last known thylacine died in 1936, but new research suggests the animals may live longer in the wild, “based on a number of things,” an expert says.

Animals That Went Extinct In 2020 And The Ones That Could Disappear After 2021

September 7, 1936 is widely regarded as the day the world’s last remaining Tasmanian tiger, also known as a thylacine, breathed its last at Hobart Zoo.

But how long will the marsupials, the last dog-like striped carnivores, remain hidden in the Tasmanian wilderness? How many years? A few decades?

According to a new analysis of 1,237 observations and sightings of the animal since 1910, the thylacine may have persisted until the late 1980s and possibly longer.

If this analysis is correct, it suggests that – had he been able or inclined – the thylacine would have stayed long enough to film the first episodes of the TV program Neighbors (1985), rather than just in grainy black-and-white. The world of the early years. 20th century.

Published in the peer-reviewed journal Science of the Total Environment, the study took all observations and assigned them a quality score, ranging from reliable records supported by a physical specimen – living or dead – to sightings by experienced Bushmen or brief glimpses of inexperienced eyes. .

Professor Barry Brooke, from the University of Tasmania and lead author of the study, worked for five years to determine the timing of the thylacine’s extinction.

He said just looking at records of kills, captures or sightings confirmed by past hunters or wildlife professionals suggests a probable extinction date between the 1940s and 1970s.

Extinct Animals Could Suddenly Be Brought Back To Life

But he said that instead of eliminating the follow-up observations, the study included them in the model, greatly reducing the likelihood of their authenticity.

Using this approach, the observations and date of extinction before 2019 shifted from the late 1980s to the early 2000s.

Brook says regular and reliable sightings remained until the 1960s. But as the years went by, there was a “natural decay” of people who had been around long enough to ever see it.

“But if you’re talking about people who knew about the wildlife, then there were still occasional credible sightings in the 1980s,” Brook said, referring to the experience of park ranger Hans Naarding, who told leaders in 1982 that he was left on foot. A few minutes with him. His torch was staring at the thylacine.

Animals We Thought Were Extinct But Actually Aren’t

Brooke said the death of a thylacine in 1936 at Hobart Zoo remains the last sighting to be supported by photographic evidence.

The International Union for Conservation of Nature officially declared the thylacine extinct in 1982, after decades of unsuccessful attempts to find them.

In addition to offering a new perspective on when the last thylacines may have died, the study also analyzed the observation sites.

Brooke said based on the new research, the most likely location for the most recent thylacines was “somewhere in the middle of northwest Tasmania” around Waratah.

He said the work also offered a method to help conservationists search for other species they fear will become extinct.

“This pattern of range contraction and decline is very typical of pre-extinction, so understanding it better can be really helpful in knowing where to look.”

Prehistoric Animals That Could Still Exist Today

Although a small group of enthusiasts maintain that the thylacine still exists, Brooke says there is a “less than 1%” chance that the animal still survives anywhere.

Dr Steven Sleightholme, co-author of the International Thylacine Specimen Database study, said the thylacine had “captured the public imagination for decades and inspired many efforts to demonstrate its continued existence”.

Professor Andrew Pask, from the University of Melbourne, is part of a team trying to find ways to revive the thylacine using the animal’s DNA, supported by genetic samples from its relative, the numbat.

Pask — who was not involved in the new study — said the study was “based on many possibilities.”

Animals That Scientists Are Trying To Bring Back From Extinction

He said that because thylacines looked like dogs, he thought that many people who believed they had seen one might just be seeing modern dogs.

He said: “It would be conceivable that some of the animals were probably still in the world [after the 1936 deaths], but I think it is unlikely that the thylacines would have survived more than a few generations. And we think each generation is about eight years old.

“It’s like our Loch Ness monster or Bigfoot, almost a mythical creature, but I like [some people think they see them] because it keeps the memory alive and reminds people of this extraordinary animal that we hunted before extinction. .” With advances in technology, it is now possible to bring many extinct animals back to life. Here are some animals whose resurrection scientists are considering.

Everywhere they went, humans drove animals to extinction, whether those animals were hunted to extinction or simply outcompeted. This is not a new phenomenon. Tens of thousands of years ago, the disappearance of megafauna anywhere in the world coincided with the arrival of humans. The famous woolly mammoth in Europe has disappeared. In America, strange animals like Glyptodon were hunted to extinction, and in Australia, 85% of animals weighing more than 100 pounds became extinct after humans arrived! It included omnivorous kangaroos, large koalas and huge wombats.

Tasmanian Tiger Rna Is First To Be Recovered From An Extinct Species

More recently, human activity has led to the extinction of the moa, the passenger pigeon, and the dodo. But does this mean that these species are gone forever? Here are six extinct animals that scientists want to bring back from the dead.

The only photograph of a living quagga taken in 1870 shows a mare at London Zoo via ThoughtCo.

The quagga was a subspecies of plains zebra that roamed the southern tip of Africa. It was distinguished by stripes on the head and front half of the body, while the back half was brown. It was hunted to extinction in the wild and the last specimen died in 1883 in Amsterdam Zoo.

The Quagga Project aims to right human wrongs by bringing this extinct animal back to life. As far back as the 1950s it was suggested that Quaggas could be bred through selective breeding. In 1980, this theory got a big boost when mitochondrial DNA research showed that the quagga was indeed a subspecies of the plains zebra.

In 1987, nine zebras were selected and transferred to a specially constructed breeding camp near Robertson, South Africa. This was the beginning of the quagga breeding project. Since then, other zebras have been selected for their quagga-like characteristics and entered into the program; However, the increase in the number of zebras required the expansion of the project to other areas where the zebras could be cared for.

Since the beginning of the project, many foams have been born and subsequent generations have produced results. So far, the six people are almost identical to the original quagga. Although not quite a quagga yet, these individuals are known as Rau quaggas. Henry, Freddie, DJ14, Nina J, FD15 and Khumba are the six zebras running the project.

During the Pleistocene epoch (2,580,000 to 11,700 years ago), a huge species of livestock called aurochs was widespread in Eurasia, North Africa and the Indian subcontinent.

Extinct Animals You Might See Alive Someday Soon

By the time human civilization began, the species had already declined massively from its peak. In Roman times, only European aurochs remained. A thousand years later, the last aurochs lived only in a small group in the forest of Poland. By 1627 they were extinct.

The first attempts to revive the aurochs began in the 1930s by Heinz and Lutz Heck, who selectively bred modern cattle. The result was interesting, but gave birth to a breed called “Heck cattle”, which differed significantly from the original aurochs.

Currently, several organizations are trying to revive this extinct animal. The Tauros Program and the Taurus Project both seek to revive aurochs using selective breeding, while the True Nature Foundation’s rival Uruz Project wants to.
