Scientists plan to resurrect Tasmanian tigers that have been extinct since 1936 – National


The phrase ‘die and disappear’ may not be so far-fetched anymore.

Almost 90 years later extinctionScientists are currently trying to revive the Tasmanian tiger (officially thylacine), a carnivorous marsupial that formerly lived in the Australian bush.

In a pioneering scientific endeavor unlike in the movies Jurassic ParkDallas-based genetics company Colossal Biosciences announced Tuesday that it is working to remove thylacine to improve biodiversity and the climate.

According to the company’s official website, DNA Collected from long dead thylacines will be used to bring the animal back.

Colossal Biosciences states that thylacine faces anthropogenic extinction. Once considered a pest by European settlers in Australia, the apex predator usually feeds on livestock. For this reason, a bounty was placed on the animal in 1830 and it was intensively hunted.

Colossal Biosciences states that the last wild thylacine was killed between 1910 and 1920. The last thylacine, named Benjamin, died in captivity in 1936 at Beaumaris Zoo in Hobart, Tasmania. The species was granted protected status in Australia that same year, but it was too late for the former apex predator.

Colossal Biosciences writes on their website: “At the top of its own food chain, thylacine plays an important role as a guardian of the environmental health of the regions it inhabits. “Its role as apex means it helps to eliminate weak and sick ones and keeps the balance against competitors, helping to ensure species diversity.”

Scientists claim when a predator like thylacine disappears, a process called “Nutrition Reduction” begins.

According to Science.org, the extinction of the apex predators “could be due to humans the most pervasive influence on nature. “The subtropics play a role in the presence of disease, wildfires, carbon sequestration, invasive species, and biogeochemical cycles in nature.

Of course, the scientific process for reviving thylacine is not an easy one. Researchers will need to use cutting-edge science and technology such as gene editing and intrauterine insemination to successfully meet the project’s goals.

Using a 108-year-old specimen preserved at the Victoria Museum in Australia, Colossal Biosciences announced they will “generate high-quality reference genomes for all Thylacine’s closest relatives to determine concordance.” best for engineering.”

From there, the scientists would identify a “recipient” and use genome engineering to insert thylacine genes into the genome of a fat-tailed dunnart.

The fat-tailed Dunnart, a rat-like marsupial, is the closest relative of the thylacine. According to CNN, size difference of the two animals (with the thylacine being 51 to 69 cm tall, and the fat-tailed dunnart only 60 to 90 mm long) is not an issue. This is because “all marsupials give birth to tiny young, sometimes as small as a grain of rice,” CNN reports.

According to Colossal Biosciences, countless other scientific procedures are used to ensure a fully formed embryo is successfully placed in its surrogate body, where it will carry a pregnancy for 42 days, according to Colossal Biosciences.

“Our work is not done with the introduction of the first extinct thylacine,” the company wrote. “In partnership with universities, zoos, governments, wildlife conservation groups and more, we will focus on livestock efforts to promote healthy populations in safety conditions.”

The extinction of thylacine is not the only project of Colossal Biosciences. The company also received an investment of US$15 million (over $19 million) last year to revive it woolly mammoth.
