Extinct Creatures That May Still Exist – With the advancement of technology, many extinct animals can now be brought back to life. Here are some of the animals scientists are considering for resurrection.
Wherever humans have gone, animals contribute to extinction, whether those animals were involved in the extinction or the exit. This phenomenon is not new. Ten thousand years ago, the disappearance of megafauna around the world coincided with the arrival of humans. In Europe, the famous woolly mammoth has disappeared. In the Americas, exotic animals like the glyptodont were driven to extinction, while in Australia 85% of animals weighing 100 pounds became extinct after humans arrived! These include omnivorous forms, koalas and giant and giant martens.

Extinct Creatures That May Still Exist
More recently, human activities have led to the extinction of the moa, the passenger pigeon and the dodo. But are these species permanently lost? Here are six extinct animals that scientists hope to bring back to life.

The quagga is a species of plains zebra that lives in the southern tip of Africa. This is unique in that it has stripes on the head and front of the body, while the back is half brown. It was hunted to extinction in the wild, with the last specimen dying at the Amsterdam Zoo in 1883.
Project Quagga aims to right the wrongs of people by bringing this extinct animal back to life. In the early 1950s, it was suggested that the quagga could be regenerated through selective breeding. The theory got a major boost in the 1980s when mitochondrial DNA studies proved that the quagga was indeed a species of plains zebra.
In 1987, nine zebras were selected and a breeding farm built near Robertson, South Africa. This is the beginning of the quagga rebreeding project. Since then, more zebras have been selected and included in the program for their quagga-like characteristics. However, the increase in zebra numbers requires planning to increase the number of areas where zebras can be cared for.

From the beginning of the matter, many horses were born, and the offspring came to fruition. So far the six men are almost identical to the original quagga. Although not quite quaggas, these people are known as Rau quaggas. Henry, Freddy, DJ14, Nina J, FD15 and Khumba are the six zebras driving this project forward.

During the Pleistocene Epoch (2,580,000 to 11,700 years ago), a large species of cattle called aurochs was widely distributed throughout Eurasia, North Africa, and the Indian subcontinent.
At the beginning of civilization the numbers of species had fallen significantly from their peak. In Roman times, only European heathens remained. A thousand years later, the last bison lived in small herds in the forests of Poland. 1627 they were extinguished by

The first attempts to bring back bison began with Heinz Heck and Lutz Heck in the 1930s, who selectively bred modern cattle. The result was interesting, but the result was a type called “Huck”, which is very different from the original bison.
Several organizations are now trying to revive this extinct animal. Both Project Taurus and Project Taurus are trying to renew the bison through selective breeding, while the True Nature Foundation’s rival Project Uluz hopes to use genome editing in its plans.
It is hoped that bringing the extinct animal back to the wild in Europe will benefit European ecosystems, as the bison species are a cornerstone. Even huge animals are expected to attract tourists.
The Iberian ibex, a species of Spanish ibex, is an extinct animal that disappeared due to the flooding of the 19th and 20th centuries. In 1999, the last Pyrenean ibex, a female named Celia, was tagged and collected. Tissue samples were taken from her and released into the wild. A year later it was found crushed by a tree.
Dangerous Extinct Animals
In 2003, scientists used a tissue sample to clone Celia. His cells were transferred into goat eggs. Many of the goats conceived, but only one was carried to term. The clone was born with defective lungs and lived only seven minutes. Despite the sad results of this search, the experiment was considered a huge success in bringing the Pyrenean ibex back to life.
The problem is that scientists only have DNA from female ibex. Scientists plan to solve this problem by breeding clones with relatives of the ibex of southern Spain. This would produce a hybrid that could be further bred to resemble the Pyrenean ibex.

Commercial hunting wiped out the passenger pigeon in the early 20th century. Once millions of animals roamed the skies of North America, these now extinct animals may be making a comeback.

The problem is the complete lack of DNA, so there isn’t a viable method for breeding birds. However, the conservation group Live & Restore has not been successful in identifying DNA mutations that cause phenotypic differences between carrier pigeons and tail pigeons, their closest living relatives. In this way, the DNA of the tail pigeon can be changed to give it the same nature as the carrier pigeon. The resulting hybrid will not be the exact shape of the carrier pigeon, but will be almost indistinguishable from the original animal.
The plan is now in full swing, with captive breeding planned for 2024 and plans to release large hybrids into the wild by 2030.

They once roamed the continent of Australia, New Guinea and Tasmania, before the Europeans came to Australia, the marsupial people declined. The Australian government has done little and too late to save this animal. In 1936, the Tasmanian government declared the thylacine officially protected. Fifty-nine days after the news broke, the last known specimen, named Benjamin, died of neglect at Hobart Zoo.

In 2017 it was announced that the complete nuclear genome of the thylacine had been sequenced. The next step will be to create a fully functional genome, explains Andrew J. Pask of the University of Melbourne. While it will take time and a lot of research, it’s estimated that all efforts to save the thylacine from extinction could begin as early as 2027.
The most famous extinct animal that is considered to be re-extinct is the mammoth. From a prehistoric perspective, the extinction of the mammoths was relatively recent. They left around 1650 BC. This is more than a thousand years since the Giza Pyramids were built!
For more than a decade, research teams from countries like Japan and Russia have been studying how mammoths resurrected. Various methods were proposed. This sophisticated method, which requires mammoth DNA, is not yet feasible because not enough DNA has yet been found, although more is being discovered regularly, especially as the extent of permafrost recedes. Another method is artificial insemination using mammoth sperm and an Asian elephant mother. A third approach is the mammoth genes in Asian elephants.
Regardless of the success of the approach, it is hoped that bringing back the mammoths will immediately benefit the intended environment. It is estimated that this animal can actually help reverse the damage of global warming. A recent Newsweek article claimed that these extinct animals could be brought back to life as soon as 2027.

Humans may differ between animals and humans, but from a scientific perspective Neanderthals, like Homo sapiens, are considered animals. They are also candidates for extinction, although the moral debate will continue long after the operation is over (if at all).
Wise man (us) did not evolve from Neanderthals. We and our Neanderthal cousins likely descended from a common ancestor, Mus heidelbergensis. Neanderthals became extinct about 40,000 years ago, but not before Homo sapiens met and interbred with their ancestors (although since we are a different species, pregnancy would have been difficult and often resulted in sterile offspring). In fact, the ancestors of some Neanderthals.
Neanderthals were intelligent, like us, they were excellent problem solvers, and like us they were social creatures who loved to sit around the campfire and share stories. But they are different enough to be considered separate species (or even a
