Will the return of extinct animals be the same as in “Jurassic Park”?
From humanity's innate desire to restore extinct species, the concept of the concept of resurrection.
The idea of resurrecting extinct species using genetic engineering has caused controversy among scientists. Revive & Restore, founded by George Church and Stuart Brand, aims to genetically save endangered and extinct species. They propose using hybrid animals created from living beings and CRISPR technology. For example, they are working to reintroduce the extinct passenger pigeon by replacing the genes of modern bandied pigeons with those of passenger pigeons. They are also aiming to boost the population of endangered Asian elephants by editing the genes of extinct hairy mammoths into modern elephants. This technology aims not only to bring back extinct species, but also to prevent future extinctions.
In 2018, Brand and Church traveled to Siberia, where Russian scientists are trying to recreate the grassland ecosystem where woolly mammoths once lived. As mammoth numbers dwindled, the pastures were taken over by foliage.
Church said mammoth-Asian elephant hybrids could once again inhabit Russia. He also urged everyone to "relax" about the prospects of hybrids. According to him, a lot of hybridization occurs in mammals. "I'm part Neanderthal," he said, referring to scientists' estimates that about 20 percent of Neanderthal genes are present in modern humans.
Rothschild and McPhee said. Will this hybrid be released into a world without natural predators? How does a mammoth know how to be a mammoth if there are no other mammoths around? “You have all the problems of not having a mom” and not having other animals to learn from, Rothschild said. These animals "will suffer because of something we could have handled differently," she said.
Rothschild went further, wondering whether someone might try to resurrect a Neanderthal for the sake of commerce or simply in the name of science. This idea, according to Rothschild, was morally wrong.

The idea of resurrecting extinct species using genetic engineering has sparked controversy among scientists. Revive & Restore, an organization founded by George Church and Stuart Brand, aims to genetically save endangered and extinct species. They propose using hybrid animals created through CRISPR technology, such as reintroducing the extinct passenger pigeon and boosting the population of endangered Asian elephants. This technology not only aims to bring back extinct species but also prevent future extinctions.
In 2018, Brand and Church visited Siberia, where Russian scientists are recreating the grassland ecosystem for woolly mammoths. Mammoth-Asian elephant hybrids could potentially inhabit Russia again. However, there are concerns about releasing these hybrids into a world without natural predators and without other animals to learn from. Some experts argue that these animals may suffer as a result.
Additionally, there are ethical concerns about potentially resurrecting a Neanderthal for commercial or scientific purposes. Some argue that this idea is morally wrong.
Overall, the concept of resurrecting extinct animals through genetic engineering is causing debate among scientists, with considerations on the impact on ecosystems and ethical implications.
