September 7, 1936. Hobart, Tasmania. It was a cold night. The keeper forgot to lock the shelter door. And so, the last known Thylacine—a striped, wolf-like marsupial named Benjamin—paced his concrete cage until he froze to death. Just like that. Gone. Blink and you missed it.
He was the end of a lineage that stretched back millions of years. But here is the scary part. He wasn’t just a tragedy. He was a warning shot.
The Thylacine famously went extinct back in 1936. At least, that is the official story. We will get to the rumors, the sightings, and the wild conspiracy theories about cloning later. But first, we have to look at the bigger picture. The much, much bigger picture.
With species disappearing in their thousands, our planet may be on the verge of a mass extinction event. Actually, scratch that. We aren’t “on the verge.” Many experts think we are already falling off the cliff.
The Kill Switch: Understanding Mass Extinction
Most people think extinction happens slowly. A few birds die here. A frog disappears there. Evolution takes its course, right? Wrong. Real mass extinctions are violent. They are abrupt. They are the planet hitting the reset button with a sledgehammer.
Mass extinctions have occurred a total of five times in our planet’s 4.5 billion-year history. These aren’t just bad weekends. These are biological apocalypses.
Some, such as the disappearance of the dinosaurs following an asteroid strike 65 million years ago, are particularly well known. You know the story. A rock the size of Manhattan slams into the Yucatan. Dust blocks the sun. Photosynthesis stops. Starvation sets in. The monsters that ruled the earth for 165 million years? Gone in a geological heartbeat.
But others, such as the Late Devonian extinction, are not as famous. They should be. Consider the “Great Dying”—the Permian-Triassic extinction event. It happened about 252 million years ago. Ninety-six percent of all marine species died. 96%. Life on Earth almost ended completely. It took 10 million years for the planet to recover.
The Statistical Nightmare
A mass extinction is typically defined as an event in which three-quarters of all plant and animal species on the planet go extinct within the space of one million years. That sounds like a long time to us humans. But to the Earth? It’s a blink of an eye.
And now it appears as though this might actually be happening again right under our noses. But this time, there is no asteroid. There are no super-volcanoes erupting in Siberia. There is just us.
The Smoking Gun: What the Science Says
In a new study published in Science Advances, scientists have outlined the fact that over the last few thousand years, we have been seeing species disappearing at unprecedented levels. We are talking about rates that defy natural explanation.
“The loss of biodiversity is one of the most critical current environmental problems, threatening valuable ecosystem services and human well-being,” the study authors wrote. That is academic speak for “We are in big trouble.”
“A growing body of evidence indicates that current species extinction rates are higher than the pre-human background rate, with hundreds of anthropogenic vertebrate extinctions documented in prehistoric and historic times.”
Let’s break that down. “Anthropogenic.” That means human-caused. We are the asteroid. We are the volcano. From the moment our ancestors picked up spears and started marching out of Africa, the megafauna started dropping. Woolly Mammoths? Hunted. Giant Sloths? Gone. The Dodo? Eaten.
The Ghost of Tasmania: A Case Study
Let’s circle back to the Thylacine. The Tasmanian Tiger. This creature is the poster child for the 6th Extinction. It looked like a dog, had stripes like a tiger, and carried its young in a pouch like a kangaroo. It was a biological masterpiece.
Why did it die? Because we decided it was a pest. Bounty hunters were paid to bring in their skins. Farmers shot them on sight. By the time we realized our mistake, Benjamin was shivering in that Hobart zoo.
But here is where things get weird. This is where the alternative history and cryptozoology crowds start whispering.
The Lazarus Effect
Is the Thylacine really gone? Official science says yes. But every year, hundreds of reports come out of the deep Tasmanian bush. Farmers claim to see striped dogs. Campers hear strange yipping sounds that don’t match any known fox or dingo. Is it possible a small population survived? Or are these just ghosts of our guilty conscience?
There is a concept called the “Lazarus Taxon.” It refers to species that disappear from the fossil record, are presumed dead for millions of years, and then—boom—they are found alive. The Coelacanth fish is the classic example. We thought it died with the dinosaurs until a fisherman caught one in 1938. If a fish can hide for 65 million years, can a tiger hide for 80?
Genetic Necromancy
Even if Benjamin was truly the last one, he might not be the end. There are serious, well-funded projects underway right now to bring the Thylacine back. Companies like Colossal Biosciences are using CRISPR gene-editing technology to splice Thylacine DNA (preserved in alcohol jars) with modern marsupials.
Think about that. We wiped them out. Now we are playing God to bring them back. It sounds like the plot of a sci-fi horror movie, but it is happening in labs today. If we can resurrect the Thylacine, what else can we bring back? Mammoths? Sabre-tooth cats? Where does it stop?
The Domino Effect: Why You Should Be Scared
You might be thinking, “Okay, so the Tasmanian Tiger is gone. Sad, but how does that affect me? I still have my iPhone and my coffee.”
Here is the reality check. Nature is a Jenga tower. You can pull out a few blocks and the tower stays standing. You can pull out the Dodo. You can pull out the Passenger Pigeon. The tower wobbles, but it holds.
But eventually, you pull out the wrong block. Maybe it’s the bees. Maybe it’s the plankton in the ocean that provides 50% of the oxygen we breathe. When that block goes, the whole tower comes crashing down.
If this species loss continues, then it could have dire consequences for mankind, in particular if food chains collapse and we are unable to produce enough to sustain our ever-growing population. Imagine a world where crops don’t get pollinated. Imagine oceans filled with jellyfish because all the fish are dead. It’s not just about losing pretty animals. It’s about starvation.
The Alternative Theory: Cycles of Doom
Let’s get a little controversial. Let’s look at the “forbidden” theories. There are historians and geologists who believe these extinction events are cyclical. Clockwork.
Some theories suggest our solar system passes through dangerous patches of the galaxy every 26 to 30 million years, disturbing comets in the Oort cloud and sending them hurtling toward Earth. This is the “Nemesis Star” hypothesis—the idea that the Sun has an evil twin, a dark star, that swings by and rains death upon us.
Others look at the rise and fall of advanced civilizations. Did you know that when the younger Dryas period hit about 12,800 years ago, a massive extinction of megafauna occurred in North America? This coincides exactly with the disappearance of the Clovis people. Was it a comet? A solar flare? And if it happened then, could it be why we find so many “out of place artifacts” and sunken ruins today?
Are we just the latest civilization to build a house of cards on a fault line? The arrogance of modern man is thinking we are the first to be this advanced. But maybe we are just the first to leave this much plastic behind.
The Closing Window
“Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing,” the study authors wrote.
That is the polite way of saying: “Tick tock.”
We are living in a unique moment in history. For the first time, a single species has the power to destroy the biosphere. But we also have the power to save it. We have the technology to track species, to protect habitats, and yes, maybe even to clone the ones we lost.
The Final Question
So, what happens next? Do we continue to pave over the rainforests? Do we watch the coral reefs bleach white and die? Or do we wake up?
The Thylacine is watching us from history. Benjamin is pacing in his cage. He is waiting to see if we follow him into the dark. Because make no mistake: if the ecosystem collapses, the rich won’t survive in their bunkers. The tech won’t save us. Biology always wins. Nature always bats last.
The 6th Mass Extinction isn’t coming. It is here. The only question left is: Are we going to be the asteroid? or the dinosaurs?
