Extinct Animals Scientists Are Close To Revive From ExtinctionSep 09, 2023
Hi, I'm Katrina, from beautiful tigers that were alive until recently to ice age rhinos, here are nine
scientistswant to resurrect number nine Caspian tiger The Caspian tiger was among the largest big cats in the world until it became
extinct. during the 1960s. It was once present in Turkey and much of Central Asia, including Iran, Iraq, and parts of northwestern China. According to the scientific alert, the loss of hunting habitat and food shortages wiped out the species just over the middle of the 20th century, according to an early 2017 study published in the journal Biological Conservation. reintroduce the Caspian tiger by releasing specimens of its genetically similar relative, the Siberian tiger, into habitats previously occupied by the Caspian subspecies; according to the authors, the phenotype of the Siberian tiger proves to be adaptable to the arid conditions of the introduction site; it would probably take more than a decade to bring it. the introduced population at a sustainable level in the Ili River delta, which appears to be the most appropriate place to try to
revivethe Caspian tiger.
There they could hunt wild boar, Bukhara deer and roe deer. An introduced population of 40 tigers could reach 100 in 50 years. their release into the habitat, which would mark tremendous progress in keeping endangered tigers on the planet, but the proposed effort has implications, including the need to ensure that tigers and humans can coexist peacefully, as well as the requirement to restore prey populations before introducing them. tigers to the region, which would take up to 15 years, but
scientistsare seriously investigating it and starting to plan just in case number 8 the dodo bird native to the island of Mauritius the dodo was a large flightless bird that grew up to 3 feet tall and weighed up to 40 pounds, became
extinctduring the 17th century after the arrival of humans and their non-native animal friends, such as dogs, cats and rats.
In a 2018 research paper, scientists suggested that it might be possible to
revivethe extinct population of dodos Using the genes of their
closest living relatives, the proposal arose following the discovery of the general genomic structure of dinosaurs, which may prove useful to bring the dodo and several other extinct birds back to life. Birds are considered dinosaurs,
closest living relatives and most recently extinct species. with genetically similar descendants may, therefore, have a chance of resurgence at the University of Kent, scientists Darren Griffith and Rebecca O'Connor wrote in a paper for the conversation, however, it is a long shot that it will be possible in the future use Jurassic Park technology to help. undo some of the damage humans have caused when asked which extinct animal would be the most fun to revive.
Biologist and ancient DNA expert Beth Shapiro told Smithsonian magazine that the dodo was an ideal candidate because it is very silly looking and has several strange features in a On a more serious note, she explained that if the dodo were brought back, It could be returned to protected habitats in Mauritius, where people could go to watch dodos in their native habitat number 7. Woolly mammoth The last surviving population of woolly mammoths became extinct around the year 4,000 years ago, on Rangel Island off Siberia, After centuries of inbreeding, when they became extinct the creatures were sickly weak, neurologically damaged and far less fertile than during their heyday, mammoths lived recently enough for scientists to collect genetic material from their remains, raising questions. . about the possibility of
extinctionusing ancient DNA doing so is more complicated than it seems, especially since there were many species of mammoths throughout the prehistoric world and scientists are still trying to figure out where each of them belongs on the family tree. evolutionary.
There is also evidence that mammoths interbred, further blurring the lines between different species and giving each species a wide variety of characteristics, but that could make them easier to recover. This complicates the process of reviving mammoths, although it leaves scientists with difficult decisions about what traits they have. I would manually select them to incorporate them into the mammoth offspring. Cloning mammoths is not currently possible because doing so would require an intact, viable mammoth cell which is unlikely to ever be found according to biologists and former DNA expert Beth Shapiro; However, other scientists believe it is possible. and they claim to be working on it right now with DNA taken from intact frozen mammoths found in Siberia.
The most likely method of bringing back mammoths would involve modifying the DNA of their closest modern pachyderm relative, the Asian elephant, to make it more like the ancient creature. In the case scenario, any scientist created using this method would still be a product of guesswork. This new creature could lack genetic variations that mammoths possessed at certain times or in specific regions; even if the genetically modified mammoth-like animal appeared genuine, it would have to be able to survive in environments very different from those in which its
animalslived. ancestors, since the world has changed a lot in 10,000 years, the most likely places would be the coldest ones where mammoths could get enough food and now for number six, but first make sure to subscribe if you're new here and let me know your opinion in the comments below if we try to bring these animals back to life, if so which ones and why number 6. stellar sea cow like sirenius, the stellar sea cow was most closely related to scientist george wilhelm stellar of dagong and manatees He first described it in 1741 during a voyage across the Bering Sea while stranded on a star island and his crew found colonies of these sea cows that were up to 25 feet long and weighed up to six tons each.
Within 27 years of the star's discovery, the species was completely wiped out due to overhunting after spending millions of years as an important participant in its marine ecosystem. The stellar sea cow was more or less wiped out in the blink of an eye after surviving the Quaternary
extinction. event at the end of the Pleistocene epoch stellar sea cows were found exclusively in frigid arctic waters their rapid extinction helped raise awareness in the academic community that it is actually possible to completely eliminate a marine species in human hands the role of Humanity in the animal's disappearance inspired some scientists and experts, including science writer Carl Zimmer, to advocate for its resurgence, but researchers certainly know very little about the species, leaving them to speculate about its behavior in biology and whether to return it. life is not even an option number 5. the labrador duck The labrador duck is believed to have become extinct in the late 19th century due to causes suspected to be related to humans, despite its reputation for not tasting very well, the bird It was already rare when European settlers arrived in North America.
The last specimens were collected during the 1870s and late 1870s. The known sighting occurred in 1878 in Elmira, New York, bird expert Brian Fox Ellis told Star Gazette in late 2016 that it is a sea duck that was found almost exclusively along the Atlantic coast between Baltimore and the Bay. of Chesapeake and Labrador and was rarely found inland, so why it was found here I am not sure, therefore there is little information available about the Labrador duck and there are only 55 specimens preserved in museums around the world. Scientists are not sure what their breeding habits are and the extinction of the species remains a mystery just like humans.
Their eggs may have been overhunted or driven from their natural habitat or they may have been victims of the feather trade, but it's hard to say for sure what happened. Some bird enthusiasts believe that the Labrador duck was never completely extinct and that there are some individuals and populations that resist discovery, but in Ellis' words, this bird is gone and it will take another heaven and another earth to create another. species, such as a January 2017 science alert article that said scientists want to bring back the Labrador duck, but information on this supposed effort is scarce, leaving us to wonder if reviving the species is really part of the plans. from some researcher number 4. woolly rhinoceros Woolly rhinos live during the same ice age period as woolly mammoths, but their remains are much rarer, scientists also know much less about including their location on the evolutionary timeline and information about their lifestyles and habits, the species became extinct approximately 14,000 years ago after roaming Eurasia for hundreds of thousands of years for reasons that are not entirely clear.
Researchers have long speculated that human activity, such as overhunting, could also be suspected of having wiped out the creature, but research recently published in the journal Current Biology suggests that climate change played a role in the disappearance of the woolly rhinoceros, while the species' demise occurred about 16,000 years after humans reached its In this region, its extinction also coincides with a 2,000-year-long period of severe warming known as Bowling Allorod Interstadial . During this time, the ice sheets melted rapidly and sea level rose approximately 50 feet. Woolly rhinos may have been unable to cross the Bering Land Bridge that once connected modern-day Siberia to Alaska due to their inability to adapt to the tundra climate, leaving them with no choice but to perish.
In 2015, only a few intact woolly rhino specimens were discovered. The complete carcass of a seven-month-old woolly rhinoceros is known. When Sasha was found on a frozen bank of a Siberian river, offering a glimmer of hope about the possibility of harvesting genetic material, scientists began to entertain the idea of being able to clone the extinct creature. As of now, the process seems tremendously complicated and is therefore unlikely to happen very soon. but it has also not been ruled out as impossible, apart from the fact that the woolly rhino has no known modern relatives suitable for use in the extinction process and bringing non-existent animals back to life raises significant ethical dilemmas that leave experts with questions about whether they should revive long-gone creatures, even if they can, right now our current rhino survival hangs by a thread, so there is a lot of debate about whether it would be a good idea to bring back an extinct one number 3.
Irish moose The Irish elk was one of the largest species of deer that ever existed, with antlers measuring up to 12 feet wide. It wandered throughout Eurasia mainly during the Pleistocene; The most recent known remains of the creature date back to about 7,700 years ago. The animal's range was not restricted. In Ireland it received its name because of the surprisingly well-preserved fossils that have been found in the country. Irish moose carcasses are increasingly turning up amid melting permafrost in Siberia, offering scientists a potential opportunity to collect their DNA and perhaps clone them or use other means. To bring them back to life the species is believed to have become extinct as a result of their antlers becoming unmanageably heavy and large.
Another theory suggests that Irish moose were unable to cope with a warming climate, raising the question of whether it would be wise to try to do so. bring them back with less land than ever for wild animals to roam on and a rapidly changing climate the planet may not be in the best condition to welcome the return of a gigantic mammal the sad reality is that if the Irish moose came back to life Today, it can most likely only survive under human supervision in a zoo or laboratory number 2. The idea of using Jurassic Park technology to revive extinct species has become increasingly realistic in recent years, especially when it comes to recovering ancient birds and The extinct flightless bird endemic to New Zealand called the Little Bush Moa is among the leading candidates for revival.
The Little Bush Moa abruptly went extinct during the 13th century due to overhunting, but in early 2018, a team of researchers at Harvard University announced that they had successfully assembled a nearly complete genome of the bird that offers hope for its eventual back into existence using innovative DNA sequencing technology. They inserted genetic material from the extinct moa into an emu egg and then painstakingly assembled the 900 nucleotides into their correct positions throughout the study. The researchers determined that the moa wasRelative to the kiwi ostrich and emu, there were nine species of moa in total, with the little bushmoa being the smallest and most common among them.
On average, the small bush moa stood four feet tall and weighed about 66 pounds, while some scientists favor trying to revive it. Other ancient birds don't think it's a great idea, but the idea of extinction isn't necessarily limited to bringing back extinct species. It could prove useful in saving modern creatures facing the threat of extinction. De-extinction could be useful in inspiring new science and could be beneficial for conservation if we ensure that it does not reduce existing conservation resources. University of Queensland scientist Hugh Possingham said in a statement. However, in general, it is best if we focus on the many species that now need our help, number 1.
The Pyrenean ibex. Bucardo or Pyrenean ibex was a subspecies of Spanish ibex that was formally declared extinct in 2000, when the last known surviving female was found dead in Spain. The animal's disappearance came after a 200-year period of increased hunting in the region and scientists' interest in its revival came almost immediately after its extinction in 2009, using genetic material collected from frozen skin samples. of the last surviving Pyrenean ibex. The researcher and author of the study José Fulch and his colleagues created cloned embryos by inserting the DNA of the deceased creature into goat eggs that were emptied of their own material.
These eggs were implanted in 208 specimens of the Spanish ibex subspecies, seven became pregnant. and only one came to term - the calf died of respiratory failure immediately after birth, something researchers expected. Despite the infant's death, experts praised the resurrection as a major scientific achievement, but warned people to avoid have too many hopes about the process. The public should not conclude that we are on the verge of cloning mammoths or woolly dinosaurs. Scientist David Wilt told National Geographic that even if such embryos could be constructed there are no suitable surrogate mothers for long-dead species. Thanks for watching.
