Would you use your knowledge of genetic engineering to bring back an extinct organism?
Scientists have already finagled a few ways to resurrect extinct species from their evolutionary graves. Genetic engineering depends on existing DNA samples of the extinct species; scientists could bring them back to life by targeting and replacing specific genomic sequences in a closely-related living species.
Could extinct animals be resurrected?
There are some species that are extinct that before the last individual died, living tissue was taken and put into deep freeze. So it’s able to be brought back as living tissue. The only way extinct species could be brought back is if there is living tissue that’s going to be found.
Will it be possible to resurrect extinct species using DNA?
It’s not possible. The limit of DNA survival, which we’d need for de-extinction, is probably around one million years or less. Dinosaurs had been gone for a very long time by then.
Why extinct animals should not be brought back to life?
Bringing back extinct species could lead to biodiversity loss rather than gain, according to new work. The research suggested further stretching already-strained conservation budgets to cover the costs of de-extinction could endanger extant species (species still in existence).
What is your view about the process of bringing extinct organisms back to life?
Cloning is a commonly suggested method for the potential restoration of an extinct species. It can be done by extracting the nucleus from a preserved cell from the extinct species and swapping it into an egg, without a nucleus, of that species’ nearest living relative. Cloning has been used in science since the 1950s.
What are some possible advantages to bringing back extinct animals?
List of Advantages of Cloning Extinct Animals
- Bringing back an extinct animal can offer important scientific knowledge.
- Cloning an extinct animal signals a huge step in genetic engineering.
- Bringing extinct animals back can help the environment.
- The exploitative nature of man will likely kick in.

What extinct animals have we brought back?
Meet Five ‘Extinct’ Species That Have Returned to Life
- Elephant Shrew. The last time anyone recorded a sighting of the Somali elephant shrew was almost 50 years ago, after which, it was assumed to have become extinct.
- Terror Skink.
- Cuban Solenodon.
- Bermuda Petrel.
- Australian Night Parrot.
How much would it cost to bring back extinct animals?
Scientists are talking for the first time about the old idea of resurrecting extinct species as if this staple of science fiction is a realistic possibility, saying that a living mammoth could perhaps be regenerated for as little as $10 million.
What techniques are required to bring an extinct species back to life?
Cloning, stem cell manipulation, genome reconstruction, and genome editing are powerful technologies with significant ethical ramifications when applied to de-extinction. The expense and inefficiency of SCNT, for example, has raised questions about its practicality for resurrecting extinct species.
How would de-extinction affect the environment?
Potential impacts of de-extinct species remain uncertain; they may improve ecosystem function, or hinder conservation efforts and damage socio-ecological systems.
Should extinct species be brought back into existence essay?
It is clear that that extinct species should be brought back into existence due to the many benefits that they would provide for us. Although there are potential problems that may arise from reviving extinct species, they can be solved relatively easily and do not outweigh the good that comes from de-extinction.
Is it possible to bring back extinct species?
But it’s not just about bringing back the dead. The same techniques being developed to help resurrect extinct species can also be used to help save living species on the brink of extinction. So how does de-extinction work, what are its limits, and do we really need to bring back long-dead animals?
What was the first animal to be brought back from extinction?
The first milestone was in 2003 when European scientists resurrected the Pyrenean ibex, a type of mountain goat that had gone extinct a few years earlier. Sadly, the kid died a few minutes after she was born, so the poor ibex was not just the first animal to be brought back from extinction, but also the first to go extinct twice.
Which extinct animals can be de-extinct through cloning?
Here’s our list of 14 extinct animals considered for de-extinction through cloning. Mauricio Antón / Wikimedia Commons / CC BY 2.5 Woolly mammoths seem like an excellent choice for de-extinction. Many woolly mammoth specimens remain in the permafrost of Siberia.
What are the limitations of de-extinction?
There are limitations on which species can undergo de-extinction. First up, scientists need to have a source of the animal’s DNA. Sometimes this comes from preserved museum specimens or from cells that have been collected from live animals and frozen away. Sometimes it can come from fossils.
