Endangered wolves back to life? The conflict of an American company
The prehistoric large wolves produce cloning Excitement on social networks But criticism from the experts who question the honesty and righteousness of the project, which argued that it was only a little modified ash wolves and not a true resurrection of extinct species.
The Biotechnology Organization in the United States has created extinct wolf puppies for more than 12,000 years. The relative has been enthusiastic on social networks, but criticism of scientific society
A. Huge biosensesThe US Startup, which specializes in genetic engineering, has released three young wolves with features similar to giant wolves The dog fearExtended race in North America.
This statement promises that the decision will revolutionize the science – but most experts suspect the truth of experience.
The past back?
Three wolves with white hair like ice. Colosal Bioscience introduced them The dog fear Raizen: A kind of giant wolf that disappear 12,000 years ago. Pictures and videos of these puppies were baptized Romel, Remo and KhaliThey spread fast on social networks, along with brave ads from the company.
“For the first time in humanitarian history, we have revived the successful dried race,” he declared heavily.
How big wolves were created
According to the company, the process began with a DNA analysis collected from two prehistoric lobe fossils: About 13 thousand 72 thousand years of teeth and bone. By comparing this genetic material with modern ash wolf DNA, researchers conclude that 99.5% of this species are similar.
“By identifying the differences associated with size, muscles and coat, we have edited the gene of ash wolf to include these genetic variations,” the project’s chief scientist Beth Shapiro, explained in an interview with the AP.
Made using edition CRISPR-CAS9 TechnologyOften used in human genetics.
Then the revised particles were cloned and fitted in non -fertilized eggs in a process similar to vitro fertilization. As a result, according to Colosal Wolves with all -time stroke, similar to extinct species.
Food and behavior
Matt James, who is responsible for animal welfare in Colosal, said that puppies are developing natural behaviors such as maintaining bait and chewing bones.
“They eat cow, deer and horses. They have already started experimenting with the entire bait. They show hunting instincts, but they do not know how to kill them – they are social practices that they do not have.”
“A little modified ash wolf”
Classification of Global Ecology Professor Corey Bradshah at Flinders University:
“It’s not terrible wolf. It is a slightly modified ash wolf.”
According to the researcher, the changes in the DNA are limited and do not have entertainment of the extinct race. Bradsha also criticized the lack of strict evidence:
“When there are great promises without scientific evidence, a huge red flag will be raised,” he told Reuters.
Limited technology and genetic issues
The expert recalls that science has not yet been allowed to rebuild the full genes of extinct species. The fossil DNA is usually degraded, which is impossible to create a functional gene.
Although it is possible to clone many people, there are serious genetic risks.
“It takes thousands of genetically different animals to create a viable population. Two or three are not enough. It can lead to the hard work of the new population and rapidly extending,” Bradshah said.
“We do not even know what these wolves are,” Buffalo’s AFP Vincent Lynch told AFP to make the ash wolf to look like a large wolf.
Moral questions and environmental priorities
This initiative also increases moral doubts. Ronald Sandler, Northeast University Institute of Ethics Director, fears of focusing on similar projects:
“The most important thing is to solve the reasons. We cannot fall under the illusion that everything will be resolved by bringing back the species,” he told the AFP.
Resurrect extinct animals that are extinct
Em 2024, Ben lamCo -Founder and CEO Huge biosensesStated The company hopes to produce first hubs just like Mammoths by 2028 “Before that is likely to achieve another race”Speaking of Lam, other company represents projects: Oh Dodo (Rafus hooded) And the The tigerTasmania (Thylacinous synocephalus).
The company released in March this year Pictures of rodents with some mammoth genesIt is already creating controversy.
