The Tasmanian tiger—better known as the thylacine—supposedly disappeared for good in 1936. Yet, ongoing debate and scattered evidence keep the mystery alive.
Some researchers think there’s a slim chance a few thylacines hung on in remote spots into the late 20th century, but nobody’s found solid modern proof. That sense of uncertainty—mixed with real science—makes this whole topic oddly compelling.
Scientists try to rate each sighting, guess what wilderness might still hide animals, and debate whether we should bring thylacines back (or leave well enough alone). It’s a strange mix of hard facts, gaps in what we know, and the kind of clues that keep people arguing for decades.
Evaluating the Possibility of Surviving Tasmanian Tigers
Let’s get into how eyewitness reports, Tasmania’s wild places, and bits of physical evidence shape the odds that thylacines might still be out there. The next sections break down which sightings matter, where a thylacine could actually hide, and the evidence that most strongly suggests extinction.
Assessing Thylacine Sightings and Reports
It makes sense to judge sightings one at a time. Researchers have collected over 1,200 reports and used expert rankings to sort out which ones seem credible.
Reports from seasoned bushmen, trappers, rangers, and scientists tend to carry more weight than quick, casual claims. For instance, a 1982 report from a Parks and Wildlife ranger near Togari stands out—this guy knew wildlife and wrote up detailed notes.
Photos and footprints count for a lot more than stories. The last proven thylacine died in Hobart’s Beaumaris Zoo in 1936, and physical evidence since then is almost nonexistent. Most sightings don’t come with photos or DNA.
People often mistake dogs, devils, or feral cats for thylacines. It’s worth checking who made the report, if there’s any physical proof, and whether more than one person saw the same thing.
The Tasmanian Wilderness as a Potential Refuge
If any place could hide a thylacine, it’s probably Tasmania’s South West or central highlands. Those areas are wild, wet, and barely touched by people.
A University of Tasmania study mapped out where thylacines used to live and guessed that tiny populations might’ve survived in remote corners into the 1980s.
Researchers have set up camera traps all over—hundreds of thousands of nights in total. They’ve caught plenty of animals on film, but never a thylacine.
That doesn’t prove they’re gone, but it sure lowers the odds. Some habitat models still show little patches of forest and alpine edge where a shy predator could possibly exist.
You also have to consider threats in those places—foxes, changing habitats—making long-term survival even less likely.
Key Extinction Evidence and Controversies
The evidence for extinction is strong, but there are still a few nagging questions. The last captive thylacine in Hobart’s zoo marks the last confirmed record.
Government bounties in the late 1800s and early 1900s wiped out thousands of thylacines, pushing them toward extinction.
Some later sightings—like alleged footprints at Jane River, or reports from experts like Nick Mooney—keep the debate going. Statistical models, like the one from Barry Brook’s team in Science of the Total Environment, factor in uncertainty and still allow a tiny chance that thylacines persisted into the late 20th century.
You have to weigh all those camera-trap results and the fact that most evidence after 1936 is anecdotal or patchy.
The Science and Controversy of Thylacine De-Extinction
Scientists are now trying to rebuild the thylacine with modern genetics, cloning, and some wild new reproductive tech. Not everyone’s convinced this is a good idea—or even possible.
Cutting-Edge Techniques: Cloning, CRISPR, and Artificial Wombs
The plan is to use cloning, CRISPR gene editing, and artificial wombs to create a thylacine-like animal. Cloning would start with DNA from preserved thylacine tissue and use eggs or embryos from a close living relative.
CRISPR helps scientists tweak the differences between thylacine DNA and that of modern marsupials, filling in gaps or fixing errors.
Teams working on this have pieced together a near-complete thylacine genome from old museum samples. They compare it to living marsupials—especially the fat-tailed dunnart—to guide their edits.
Researchers say they’re making progress with lab-grown embryos that mimic a marsupial uterus, which is tricky since marsupials don’t work like placental mammals.
But every step has its own problems. Old DNA is often damaged, edited embryos might not develop right, and artificial wombs for marsupials are still experimental.
That said, these methods could help other projects—like the woolly mammoth teams using similar CRISPR tricks.
Challenges in Resurrecting Extinct Species
Trying to bring back an extinct animal is a huge challenge. Thylacine DNA from museum samples is usually broken into tiny pieces.
That makes it tough to put together a full, accurate genome or figure out which genes really matter for thylacine traits. We’re also missing a lot of info about how those genes actually worked in a living animal.
Surrogate biology throws up more roadblocks. The fat-tailed dunnart—proposed as a surrogate—is way smaller than a thylacine and has a different pregnancy timeline and milk makeup.
That could cause problems for embryo survival and proper development. Artificial wombs and new reproductive techs might help, but so far, results are limited.
And then there’s the whole ethical side. Is it fair to the animals? Would a recreated thylacine fit into today’s Tasmania? Should we spend resources on this when plenty of endangered species need help right now? Those are big questions, and honestly, there aren’t easy answers.
Key Players and Projects in Thylacine Revival
A handful of groups are really driving the thylacine comeback. Colossal Biosciences has openly shared updates about their partnership and the progress they’ve made with genome reconstruction and reproductive tools.
University teams—especially Andrew Pask’s lab—are busy piecing together the thylacine genome. They’re also experimenting with marsupial reproduction, which sounds tricky but fascinating.
You’ll find project updates and some bold claims about a reconstructed genome, plus news about growing embryos in artificial uterus devices. Independent researchers keep asking for peer-reviewed studies, which honestly seems fair if we’re going to trust this data.
Other groups, like those working on the woolly mammoth, use similar CRISPR editing techniques. Sometimes these projects help refine the science, but they also remind us just how complicated de-extinction can get.
If you’re interested in this whole saga, keep an eye out for published studies on the reconstructed genome. Trials involving the fat-tailed dunnart, genome comparisons, and results from artificial womb experiments are all worth watching.
Those are the things that’ll really show if the technical claims stack up—and maybe, just maybe, how close we are to seeing a thylacine-like animal walk again.
