Should scientists bring back extinct species?
By accurately assembling the genetic data of extinct species, researchers can inject them into the eggs of living species that are genetically close to the one they are trying to bring back to life.So bringing the species back to life is feasible, if impossible and resource intensive.
Why is bringing back extinct animals a good thing?
There are many good reasons to bring back extinct animals. All animals play an important role in the ecosystems in which they live, so when lost species are returned, so is the « job » they once performed. For example, woolly mammoths are gardeners. …and probably the same for other extinct animals.

Can we bring back the Tyrannosaurus rex?
If dinosaur DNA is not available, Researchers can’t clone real dinosaurs. Every day new fossils are discovered from the ground. However, while this could provide important evidence of the species’ morphology, its organic material has long since disappeared.
Is Extinction Worth the Price?
The researchers found that protecting the « resurrected » bird could protect the habitat of 39 species. However, Bennett said the cost-effectiveness does not include the cost of bringing that bird back to life in the first place, so even in the best of circumstances, De-extinction may end up costing more than it’s worth.
What are the risks of bringing back extinct animals?
