What If All Extinct Animals Could Be Brought Back to Life?

Who does not enjoy it when strolling or hiking through our natural world coming across a truly wild animal? Will you better get ready? As soon you may just bump into a real woolly mammoth out there on one of your walks?

No, you have not traveled back to ancient prehistory in a time machine. And no, this is not a sci-fi film shoot. The truth is that scientists will soon resurrect many extinct animals in the not too distant future, this famous symbol of prehistory will be transformed into reality. And this may help the natural world as well.

The fact is that no animal completely disappears without leaving some part of itself behind. extinct creatures leave a piece of their genome behind in some closely related animal forms. Applying artificial selection, we can cross closely related species with others similarly specimens to achieve the return of a prehistoric creature. While studying the remains of a mammoth in the Arctic, a Harvard University team of biologists got incredibly lucky.

They managed to extract the entire mitochondrial DNA from a bone that had previously been handed down from generation to generation. It turns out that the mammoth is separated from modern-day elephants by only 44 genes, mainly those responsible for cold weather resistance. In 2015, geneticists successfully implanted some of these chromosomes into the DNA of an African elephant. Interestingly, the mammoth version two point O will be somewhat better able to adapt to different environments than its ancestor thanks to improving DNA.







It will also be able to thrive in a wider range of latitudes than its forebears, and thanks to the absence of tusks, it will be a disadvantageous target. fur poachers, unless of course, someone decides to make fur coats out of its hairy skin. But the Smilodon or is they were mistakenly cold in the past. Saber Tooth Tigers might give even the boldest of poachers pause.

These prehistoric predators with their giant sweeping saber-like things disappeared from the face of the earth about 11,000 years ago, and are considered to be the first animal wiped out due to human activity. Now it's time to atone for this biological sin. The well-preserved remains of a specimen of this wild cat were found in California in the USA.

With its DNA surviving intact. One can imagine that these resurrected Saber Tooth predators might be placed in zoos together with Mamet's undoubtedly pleasing fans of the animated film Ice Age, in theory, scientists could return from oblivion.

And old dinosaurs again, that's in theory, paleontologists have been able to discover almost everything about these ancient creatures, even including the number of feathers some species had, and it would seem, it remains only to revive them using our latest modern techniques and technologies.

But in reality, it doesn't work yet. With our current technologies, DNA samples only remain useful and recoverable for about a million years. That may seem like a lot, but triceratops, for example, lived 65 million years ago, and has every chance of remaining forever, just a skeleton and the museum and a picture in your old school textbook.

So the real Jurassic Park eludes us for the moment. The most we could accomplish at this point is something like a park of the very late center zoic era and scientists is for now able to resurrect Those animals that have disappeared relatively recently, pretty historically speaking, the first candidate for such a park might be the perennial ibex. unique in that cloning has already been attempted with this wild goat his creature, the last individual died quite recently in the year 2000.

Thankfully, thoughtful individuals managed to perfectly preserved the animal's DNA in 2009, scientists tried to produce a miracle the return of the perennial ibex to the world of the living by it didn't go so well. The result puzzled everyone out of 57 embryos, only seven lead to pregnancy, and only one perennial ibex reached full term and was born and sadly, it died a few hours later.

Thus, the perennial ibex has achieved the unique status of being the only animal that has managed to go extinct twice. Scientists attempted to bringing another animal back to life on this resurrection tour the ORAC the wild ancestor of old cattle disappeared in 1627. But even after 400 years, its genetic basis is still found in the DNA of modern cows and bowls. The first experiments in this area were carried out in Nazi Germany. But alas to no avail.

This new breed called the heck bowl, though impressive in size exhibited to few of the desired traits of its wild ancestor, and subsequently, the Germans found themselves with little time to continue with the project. Now scientists are working hard on the DNA of Iraq's preserved in bones from archaeological finds, eventually planning to cross one with a domestic cow.

Biologists from University College in London have decided to try to reincarnate an animal from a somewhat earlier time. These scientists are attempting to resurrect the Irish Elk, also known as the Irish giant deer, which inhabited Europe about 13,000 years ago, this giant beast reached an astounding six and a half feet or about two meters just at the withers. That is from the hooves to the highest point on the spine, and the distance between the tips of the antlers was more than 10 feet, or roughly three meters. Amazing.

I wonder if ancient peoples use their antlers as a coat rack or maybe to dry their laundry. But I digress. I also wonder what might happen when these cute little creatures flood England you can feed them by hand, and they certainly won't be scared off by the native boxes and spaniels, a number of researchers propose that we might want to try reviving something a tad smaller. One very good option is the famous passenger pigeon.

This bird is a vivid example of humans' merciless. Until the 19th century, it was one of the most common species on Earth, with a population of up to 5 billion individuals. But people became so adept at hunting them that by the beginning of the First World War, this bird had entirely disappeared from the planet.

The revive and restore project team from the University of California compare the genome of an extinct passenger pigeon to modern relatives, and found a similarity with something called the striped pigeon. After the plant introduction of some modified genes into stem cell nuclei, scientists hope to get some specimens with a completely new set of DNA given the close relationship between the species and these amazing modern tools. Scientists promised the passenger pigeons to return in just a few generations.

Good news for car washes as given the ancient pigeons always moved in flocks there will be no shortage of customers. Some of you may have guessed at the next entry on the list of candidates, this friendly gullible creature also suffered at the hands of man. Yes, I'm talking about the dodo bird, the dodo bird was found only on the island of Mauritius in the Indian Ocean.

Many of you are probably familiar with this creature as the fabulous dodo bird character, which appeared in the fairy tale Alice in Wonderland, unfortunately flightless dodos were completely exterminated in the 17th century.

Luckily, some folks decided to stuff some of these birds for posterity. This has now come in handy after all these years in their plumage, the birds DNA has been perfectly preserved using technology already familiar to us, we'll be able to introduce this DNA into the zygote of one of the dodos closest relatives, and voila, the dodo will be back. Surely you might now be asking, why not bring back all the extinct species.

Well, in a world where overpopulation is that present a big problem, prehistoric animals would be superfluous at the moment, biologists must carefully analyze what impact these resurrected species will bring to the ecosystems they are introduced into if they will contribute to the betterment of our natural world, and will not break some delicate biological balance than a species has every chance of returning from oblivion.

However, even modern technologies cannot guarantee any ancient fun up a return to life. The mortality percentage among clone creatures is that the present prohibitively high the reasons for this are most likely in the DNA. The nucleus of the donor egg retains a certain genetic memory and resists the influence of the new genetic material. This is why each normal generation of any animal is similar to the previous one.

Alas, the same reason we cannot make hybrid cat dogs from a pairing of dogs and cats, at least not yet scientists have been rather reticent regarding another problem, something from the prehistoric world could devastate or destroy a modern ecosystem, new food chains will emerge. And if some harmless ancient birds can occupy a nice, for example, then a fierce competition and struggle for survival could begin among some hungry and enterprising predators.

Therefore, a recreated species to guarantee that it will not go extinct once more necessitates being housed in a zoo or something similar. And we're not talking about just a secure cage here, the woolly mammoth and its friends who thrived on earth 2 million years ago can only survive on vast open territories. And let's not forget that the Ice Age completely changed much of the flora for example, where the Siberian steps used to be now there's only naked tundra based on the remains found.

The best places for the returned mammoth appear to be Siberia and Yakutia, the territories of which would need to be returned to their prehistoric states, it is unlikely that the locals would be happy with such a prospect. However, the net result is likely worth it. Just imagine an ancient world never before seen by man will appear before our astonished highs from almost nowhere.

Yes, there is the fact that the resurrected animals will only be near copies of those prehistoric creatures. And this is why remember, in the beginning, I mentioned that every modern animal has the DNA of its ancestors. Well, in most species, evolution has made numerous changes over millions of years were upon the descendants of these ancient animals acquire new and altered forms.

Yes, the perennial goat may be able to be resurrected from a surrogate goat mother. But how can a scientist resurrect a feathered dinosaur whose nearest relative is a chicken? to derive such a ginormous animal from such a diminutive bird would possibly take hundreds of years and thousands of intermediate steps, with each evolving specimen needing to be housed somewhere to wait, their mating to produce the next evolutionary step? and so on, and so on.

Yes, in such a scientific setting, it would certainly be exciting to work. But even if successful, even with the best of results, it would still be just a copy. So really, the best we can do now is protect the natural world we still have that way in the future. Scientists won't even have to contemplate restoring animals lost from our era.
