Does This 70,000-Year-Old Bracelet Prove We Weren’t the First Advanced Humans?

[00:00:02]In 2008, Russian archaeologists digging in a cave near Siberia's southern border discovered what appeared to be a piece of jewelry. A bracelet made of a green reflective stone that appeared to contain a drilled hole in the center of it. The bracelet was broken, but it was polished, carefully shaped, and shockingly well preserved. But the archaeologists who made the find were not shocked by finding jewelry in a cave. They were surprised because of the specific location in which the bracelet was discovered. Because alongside the bracelet, archaeologists made another discovery. A discovery that would completely reshape what we thought we knew about the human timeline.

[00:00:42]Shortly after the bracelet was discovered, it was analyzed for its specific properties, dimensions, material, things of that nature. The preliminary studies looked closely at a number of things, but most notably the intentionally drilled hole in the center of it. Their findings suggested that the hole was drilled using a technology that we normally associate with much later periods, possibly the Neolithic era or around 10,000 BC. Okay. So, what? Well, within the same layer of sediment that the bracelet was discovered in, also known as stratum 11, archaeologists recovered a small human-like finger bone. And after DNA testing, it was determined that the DNA from the fingerbone did not belong to any known sect of the human species. Instead, archaeologists had recovered the first remains of what are now known as the Dennisovans, an extinct group of humans that coexisted alongside Homo sapiens and Neanderthalss.

[00:01:42]So, where does the bracelet fit into all of this? Well, after testing the surrounding sediment, some researchers argued that the bracelet was 40 to 50,000 years old. They also did some other studies and determined that there had been no contamination of any later human groups that were occupying that specific layer of sediment. If that interpretation is correct, then it opens up the possibility that a previously unknown group of humans possess technology that anatomically modern humans wouldn't widely use until many tens of thousands of years later. And that is where the discovery becomes very very strange because it opens up the possibility that our version of humans were not the first to advance on the earth. So the question becomes who made it? What was its purpose? And could its implications point to something deeper that we are only beginning to uncover?

[00:02:37]Hello everyone. My name is Matthew and in today's episode, we're going to be discussing one of the most paradigmshifting archaeological discoveries of the 21st century. A discovery that seemingly throws out our understanding of the human timeline as we know it.

[00:02:54]Before we even get to the bracelet, we have to talk about Denisova Cave.

[00:02:59]Because this cave is not just any random cave. Dennisova Cave has completely changed the way scientists think about ancient humans. It's located in the Alai Mountains of Siberia. It's a cold, mountainous region, which you wouldn't expect to be especially conducive to primitive hunter gatherers. And yet, this cave seems to be used by multiple groups of ancient humans over tens of thousands of years. That is the first key point here. It wasn't just Dennisovans who occupied the cave.

[00:03:28]Neanderthalss were there, too. And at some point, modern humans were probably moving through the broader region as well. So, think of the cave almost like a meeting point or a time capsule of sorts in which ancient humans kept coming back there over huge stretches of time. And because of that, it preserved a very complex archaeological record.

[00:03:47]But this is what makes interpreting the bracelet quite challenging. Because when you find something in a cave like this, it's not always easy to know who made it. Caves are messy and different layers of the cave can shift around over time.

[00:04:00]And when you're dealing with tens of thousands of years, you have to be careful about coming to conclusions too quickly. But that uncertainty is also what makes the site so fascinating because Dennisova Cave is essentially telling us that the ancient human world was far more complicated than we normally think. There were Denisovans, there were Neanderthalss, and there were modern humans. And they weren't always completely separated. They overlapped and interacted on occasion. They even had children. In fact, one of the craziest discoveries at Dennisova cave was the small fragment of a bone from a little girl scientists are calling Denny. But shockingly, Denny was determined to be half Neanderthal and half Dennisovven. We talk about these groups like their categories in a textbook. But these were real people.

[00:04:47]They were meeting each other and having children. They were living in the same regions. And maybe, just maybe, they were sharing ideas, too. That idea will matter significantly when we get back to the bracelet because the bracelet likely didn't belong to a simple world. It may have belonged to a complex world, a world where different types of humans were overlapping in ways we just don't fully understand.

[00:05:12]So, who were the Dennisovans?

[00:05:14]Truthfully, this is the part that makes the whole thing so mysterious because we actually don't really know much about them.

[00:05:22]We don't have a complete skeleton collection. We don't have a city or clear signs of settlement. We also don't have writing from these people. And if there was, whatever they left behind likely vanished over time. The point is that before we can confidently say who possessed the technology capable of creating a bracelet like this, we first have to identify a clear picture of the people who actually wore it. The Dennisovans were first identified from DNA. Scientists found a tiny finger bone in Denisova cave. They analyzed the DNA and realized they were looking at a human group that didn't line up with the modern human genome, nor did it line up with the Neanderthal genome. It was something else entirely. A whole group of ancient humans were essentially invisible to us until genetic testing were able to prove their existence. That alone should make us a little more humble and open-minded about the ancient past. Because if a whole branch of humanity can be missing until a tiny finger bone is tested, then what else are we missing? It just says we should be careful acting like the past is secure in any regard because it's certainly not. The Dennis are proof of that. And what's stranger is that even though we have very little physical remains from them, their genetic footprint is actually quite wide.

[00:06:39]Dennisovven DNA shows up in modern populations living in Australia and parts of Asia. Some people today still carry Denisovven ancestry, meaning that they disappeared as a separate group, but they didn't completely disappear.

[00:06:53]Pieces of them are still here within the human genome. And in some cases, those pieces might have actually helped humans survive. One of the most interesting examples is the Tibetan plateau. A Dennisovven genetic variant specifically in the EPAS1 gene helped ancestors of modern Tibetans adapt to the high altitude and low oxygen conditions of the Tibetan plateau. This gene regulates the body's response to hypoxia or low oxygen, preventing the overp production of red blood cells that can cause altitude sickness. It was acquired through interbreeding with Dennisovvens.

[00:07:28]Meaning this extinct group of humans who we barely know from bones might still be helping people living today. This tells us that the Dennisovvens were not irrelevant. They were not an obscure dead group of humans that have no significance. They were part of our story in ways we still don't fully understand yet. And maybe they had more advanced capabilities than even we did at the time.

[00:07:51]When you hear archaic human, you probably imagine something primitive.

[00:07:55]But if history has taught us anything, it's that labels, they lose their value when new evidence is presented to the table. Just look at Gabbec in modern-day Turkey, where archaeologists discovered that what were supposed to be hunter gatherers were far more complex than we ever thought possible. They erected what some argue to be one of the largest megalithic construction sites on Earth.

[00:08:18]They did this around 13,000 years ago, just after the end of the last ice age.

[00:08:23]It remained hidden for thousands of years and was potentially intentionally buried. So clearly our understanding of the timeline has shifted in the past even drastically. So what if the Denisovans are playing a similar role?

[00:08:36]Maybe they had their own adaptations, their own technologies, or even their own symbolic world that homo sapiens were just barely scratching the surface of at the time. And what if the reason we aren't seeing all of it is simply because the evidence is gone? Or maybe it's hidden?

[00:08:56]Let's talk about the bracelet itself.

[00:08:58]The bracelet was found in Dennisova Cave, and it was made of a dark green stone containing high traces of chlorite. The stone it was made out of would have been reflective during sunlight hours, and at night in front of a fire, it would have cast a deep green hue. And that matters because whoever made the bracelet wasn't just grabbing random rocks. They were choosing a material that had a specific look to it, a certain visual quality. With some estimates saying the closest source is 200 km away, meaning the stone either had to be transported, traded, collected from somewhere else, or brought in by someone who had access to a larger area than just the cave. That alone opens up questions. But that's not the strangest anomaly here. The bracelet was broken when they found it, but scientists were able to estimate the original shape.

[00:09:47]They determined that it would have been a thin circular bracelet with an estimated diameter of 7 cm. So, this was not a large object. Instead, it was likely something personal, which is important because it means this was not a survival tool. It was jewelry. And jewelry is different because jewelry tells you that whoever made this bracelet was thinking beyond survival.

[00:10:08]They were thinking about appearance or status or even identity or maybe even a ritual. This is where I think sometimes people underestimate ancient humans. We imagine that if people were living tens of thousands of years ago, all they were thinking about was their next meal. But then you find objects like this. Then suddenly you realize that these people were creating things that had no obvious practical survival purpose. The drilled hole is what doesn't make sense because the hole suggests something that shouldn't be possible. High-speed drilling with minimal wobble. In other words, it doesn't look like it could have been made with any crude tool. It likely had to involve a more controlled drilling technique, a technique we thought was only discovered much later.

[00:10:53]But this is where we have to be honest.

[00:10:55]The dating around this bracelet is a little messy because if you look online, there are some people confidently calling it 40,000 years old. Then you'll see other claims calling it 50,000 years old. And even some more recent sources that claim to be using more advanced testing are now claiming that it's 65 to 75,000 years old. The more I think about the Dennisovvens, the more I keep coming back to this paradox. On one hand, we barely know them. Their physical remains are extremely limited. For a while, we didn't even know they existed. They're literally ghosts in the archaeological record. But on the other hand, their genetic influence is spread across a very large area. Their DNA shows up in modern people. Their remains or genetic traces are now associated with Siberia, Tibet, parts of East Asia, Southeast Asia, and Australia. But how does that happen? How can a group be so hard to see archaeologically, but then be so present genetically? And it leads me to wonder if we're underestimating them simply because we just don't have enough evidence. Maybe they lived in small groups. Maybe they were spread out across a large distance. Maybe they used materials that just didn't preserve well. Maybe they had knowledge that was passed through practice and memory rather than writing. If that's true, then it's obvious why we don't know much. Most of their world would be gone.

[00:12:13]And this is something I think about a lot with ancient history in general. We judge the past by what survived. But that's a dangerous thing to do because what survived is not the same thing as what existed. Stones survive, ceramics survive, bones sometimes survive, but wood, leather, and cloth, those rot.

[00:12:31]Stories and songs can disappear. And techniques disappear too if nobody writes them down. So maybe the Dennisovvens were not as invisible as they seem. It's also possible that we're just looking for the wrong kind of evidence. We don't know. But those are the questions that make this worth talking about.
