Reviving the Tasmanian Tiger: A Journey from Extinction to Possibility
In an unexpected twist of fate, researchers are on the brink of potentially resurrecting the Tasmanian tiger, also known as the thylacine, thanks to a surprising discovery in a Melbourne museum. This story began when scientists stumbled upon a preserved thylacine head, astonishingly well-preserved in a bucket of ethanol, tucked away in a dusty cupboard. It may sound macabre, but this find is proving to be a crucial step toward bringing back a species that has been extinct since 1936.
Imagine a head in a bucket—putrid and gruesome. Yet, within this seemingly ghastly specimen lies a treasure trove of genetic material. Professor Andrew Pask, head of the Thylacine Integrated Genetic Restoration Research (TIGRR) lab at the University of Melbourne, described the specimen as having sat neglected for over a century. However, it contained long RNA molecules, which are key to reconstructing the thylacine's genome. Pask's enthusiasm is palpable: "This was the miracle that happened with this specimen. It blew my mind."

The ambitious project to revive the thylacine is spearheaded by Colossal, a Texas-based biotechnology company focused on de-extinction and species preservation. They have attracted significant funding, raising $235 million to support their mission, which also includes plans to recreate the woolly mammoth and the dodo. The scientists at Colossal have made remarkable progress, including the assembly of what they believe to be the highest quality ancient genome ever produced, with only 45 gaps to fill in a genetic blueprint containing approximately 3 billion pieces of information.
The thylacine was Australia’s sole marsupial apex predator, once roaming the continent but relegated to Tasmania roughly 3,000 years ago. It was hunted to extinction, with the last known individual dying in captivity. Now, with breakthroughs in gene sequencing and editing, researchers aim to create a living approximation of the thylacine. They are extracting stem cells from the fat-tailed dunnart, a close living relative, and using advanced genetic editing techniques to modify its DNA.
While researchers are excited about the prospects, there are voices of caution. Ecologists raise valid concerns about the ecological implications of resurrecting a long-lost species. What behaviors will these newly created thylacines exhibit in the wild? How will they interact with the ecosystem, which has changed drastically since their extinction? As Professor Euan Ritchie from Deakin University points out, bringing back a thylacine-like animal poses significant unknowns.
Despite the hurdles, Pask and his team remain optimistic. They believe they could have the first "thylacine-looking thing" within the next three to five years, though Pask is careful to temper expectations, emphasizing that this creature may not fully resemble the original thylacine. Nonetheless, the potential for genetic insights gained from this research extends beyond mere curiosity; they could provide valuable tools for conservation efforts aimed at protecting critically endangered species today.
In a world where extinction is a pressing issue, the quest to resurrect the Tasmanian tiger illustrates the lengths to which science is willing to go to reverse the mistakes of the past. The ambitious endeavor not only highlights our scientific advancements but also raises profound questions about conservation ethics and the future of biodiversity. As we stand on the precipice of a possible revival, it’s crucial to consider what comes next for the Tasmanian tiger and how its return might shape our understanding of extinct species and the ecosystems they once inhabited.
