DNA Study Changes Everything About the Anasazi — They Didn’t Disappear

[00:00:00]New Mexico leaders holding a press conference on the steps of our nation's capital calling for oil and gas drilling to be kept away from the sacred site Choco Canyon.

[00:00:08]>> For 800 years, every textbook said the same thing. The Anacei vanished. A civilization of master builders and astronomers who raised fivetory palaces in the New Mexico desert, then walked off the map around 1200 AD without a trace. No one could explain it. No one could find them. Then a single DNA test on bones that had been sitting in a museum drawer for a century returned a result so strange the researchers ran it three more times to be sure. What it revealed exposed an 800-year-old lie hiding in plain sight. And the truth about what really happened to the Anastasia is something almost no one is ready to hear.

[00:00:47]>> Yeah. Alongside tribal leaders, three members of our state's congressional delegation were there all saying Choco is under threat. A city that should not exist. Choco Canyon sits in the high desert of northwestern New Mexico. A shallow cut of sandstone about 9 mi long, surrounded by nothing, no river of any consequence, no fertile valley, no obvious reason, looking at it today, why anyone would build anything there at all. And yet between roughly 900 AD and 1150 AD, this empty stretch of desert became the political, religious, and architectural center of a civilization that stretched across 90,000 square miles, an area larger than Ireland.

[00:01:30]Think about that for a second. They built great houses, more than 150 of them. Starting 3,000 years ago, the Anastasi culture inhabited the American Southwest. Massive stone structures rising up to five stories tall, some containing over 600 rooms, constructed with a standard of masonry that modern builders still struggle to replicate.

[00:01:53]The walls had interior rubble cores faced in precisely cut sandstone veneer.

[00:01:58]The rooms were aligned to track the sun and moon across decades long cycles. At one site, a spiral petroglyph on Fajab but marked the summer solstice to within a matter of minutes. This was astronomical precision and they connected it all. A network of roads, some of them 30 ft wide, ran in perfectly straight lines across the canyon country for hundreds of miles.

[00:02:22]These were not trade routes in any ordinary sense. They climbed cliffs rather than going around them. They were built to communicate something about the culture that made them, not simply to move goods. At the center of it all sat the kas, circular, sunken, ceremonial chambers built into the heart of every great house. Some small, some large enough to hold hundreds of people at a time. These were the gathering places, the altars, the rooms where whatever held this civilization together was reinforced generation after generation for nearly 300 years. By every measurable standard, Chaka was extraordinary. the planning, the engineering, the astronomical precision, the scale of coordinated labor required to build it all. This was not a scattering of villages. This was something organized. And then around 1200 AD, it ended. Not gradually, not slowly. The great houses were abandoned within a few generations. The roads fell silent. The population that had built one of the most ambitious construction projects in prehistoric North America simply walked away and left it all standing. Perfect masonry, fivetory walls, ceremonial chambers full of ritual objects, empty. And no one could explain why. This ka is oriented in all its major features to the sun. The doorways are north south of each other, aligned to the meridian axis of the sun each day at noon. The textbook lie.

[00:03:49]For most of the last century, the answer was simple and it was wrong. The story that settled into textbooks across the 20th century went like this. A peaceful farming civilization, democratic, egalitarian, nearly utopian. A people who worshiped the sun and the corn and the seasons, who lived in harmony with the land and with each other, and who, for reasons unknown, eventually dispersed into the wider desert and faded from history. They were given a name borrowed from the Navajo language, Anastasia. A word now understood to carry uncomfortable connotations, which is why many archaeologists today prefer the term ancestral puebloan. But for most of the last h 100red years, Anastasia was the name attached to the mystery. And the mystery had a tidy shape. A civilization rose. A civilization vanished. Here are the ruins they left behind. That was the story in museums, in documentaries, in textbooks taught to generations of school children for decades. Here's the problem. Nearly every part of that story was built before anyone could read the bones, before ancient DNA analysis existed, before forensic tonomy existed as a rigorous discipline. The textbook version of the Anosazi was constructed from pottery, architecture, and a great deal of wishful thinking. It was a story written in the absence of the most important evidence in the entire case.

[00:05:13]When that evidence finally arrived, it didn't gently revised the textbook version. It set it on fire. What the bones said, >> the Choco and buildings are not only oriented to astronomy, but also related to each other on lines of astronomy.

[00:05:27]>> Ancient DNA analysis is exactly what it sounds like. Scientists extract genetic material from skeletal remains that have been in the ground for hundreds of years, sequence it against modern genomes, and build a biological portrait of who those people were and how they relate to populations still living today. It is in every meaningful sense a time machine made of bone. For most of the 20th century, this was not possible.

[00:05:53]Archaeologists studied the Anastasia with pottery fragments and architectural analysis and the oral traditions of descendant communities when those communities were consulted at all. The bones themselves sat in museum drawers largely unread. Then in the 2000s, ancient DNA sequencing reached a level of precision that allowed researchers to extract readable genetic material from Shakawan skeletal remains. The first study to do this at Pueblo Bonito, the grandest great house in the canyon, produced a finding that should have ended the peaceful egalitarian narrative on its own. The individuals buried in room 33, one of the most elite crypt chambers in Pueblo Bonito, were not a random cross-section of the Chakawan population. They were related closely through the female line across nine generations. This was a matrinal dynasty, a ruling lineage that had buried its dead in the same chamber for more than 300 years. Reed mats, turquoise by the thousands of pieces, conchk shell trumpets from the Pacific coast. These were not the graves of equal citizens in a democratic farming community. These were the tombs of a hereditary elite that had held power in Chako for the entire span of its rise and collapse. The textbooks described a people without kings. The DNA described a dynasty. But that wasn't the strangest thing the bones were saying. Once researchers looked at the wider genetic profile, they found something nobody was expecting. Something that didn't belong in the Southwest at all.

[00:07:25]A signal from elsewhere.

[00:07:28]When researchers compared the broader Chakawan genetic profile to the surrounding populations of the ancient southwest, something did not align. The ancestral pbloins of the wider region shared a clear consistent genetic signature detectable in nearly every skeletal sample across the four corners.

[00:07:46]But at Cho Canyon itself and particularly among the elite burials, there were additional signals. Signals that did not match the surrounding populations. Signals that appeared to have entered the Chakawan gene pool from somewhere outside the southwest.

[00:08:01]Something, or more accurately, someone had come in from elsewhere. and whoever it was had made it directly into the ruling lineage. This is not a minor finding in archaeology. Genetic discontinuity of this kind almost always points to migration, a new population arriving, a new power structure being established. And the timing of the signal concentrated in burials from the 9th through 12th centuries aligned exactly with the period when Chako Canyon was transforming from a scattering of pit house villages into the most ambitious architectural project in prehistoric North America. Something had arrived at Cho around 900 AD.

[00:08:40]Something that took up residence in the most elite spaces. Something that introduced a new genetic signal, a new architectural ambition, and a new concept of how power should be organized. The question that followed was obvious. Where had it come from? If you're already feeling the strangeness of this story, hit subscribe and tap the bell. What comes next is where the evidence stops being circumstantial.

[00:09:04]The trail goes south. The DNA could point to the answer, but not deliver it alone. To confirm the source, you need more than genetics. You need architecture. You need artifacts. You need the small cultural fingerprints that travel with human beings when they move from one place to another. So researchers looked south. They looked at the trade goods that had begun appearing in Choco around this time. Macau feathers from tropical Mexico. Copper bells from the Mesoamerican metallurgy tradition. cacao residue in ceremonial vessels identified by a biochemical analysis, a plant that grows only in the lowland tropics more than a thousand miles away. The genetic trail and the material trail agreed. The signal pointed toward the valley of Mexico. And once researchers followed it, what they found was darker than anyone had been prepared for. The valley of Mexico in the 9th century was a world in transition. The great classical civilizations of Meso America were breaking apart. Teayot Tiwa, once the largest city in the Americas, had collapsed a few centuries earlier. The Maya in the southern lowlands were entering the crisis that would empty their cities within a 100red years. And the religious traditions of Meso America with their blood rituals and theocratic elites were looking for new ground.

[00:10:23]Signs of an invasion. Around the same time the genetic signal was arriving, Cho Canyon began to change. The architecture was the first thing that struck researchers as strange. At Wupatki on the western edge of the Chakan world, archaeologists found a ball court, an actual Mesoamerican ball court of the kind used for the ritual games played across the valley of Mexico for more than a thousand years. There was no tradition of ball courts anywhere else in the southwest. It had been imported. Inside Cho Canyon itself, at the great house called Cetro Kettle, a colonated facade was built along one of the central walls. Columns arranged in a row along a ceremonial space exactly matching the architectural style of Mesoamerican temples hundreds of miles to the south. No one in the surrounding southwest was building anything like it.

[00:11:15]Later in Chako's history, someone filled the columns in as if the signature had become uncomfortable. Then came the teeth in the ceremonial heart of Pueblo Bonito. Researchers found a single file tooth, a specific style of dental modification shaped and chipped in a pattern that was common across Meso America and completely unknown anywhere north of Mexico. None. And yet there it was in the grave of an elite Chakawan. A signature that could only have been carried north by a person who had been born and raised in Meso America. The genetic data confirmed what the dental evidence was already saying. The outlier signals in the Chicoan ruling burials aligned with populations from central Mexico. Not a mass migration, a small concentrated presence deposited directly into the highest status spaces of the most powerful great house in the canyon.

[00:12:08]A picture was beginning to assemble itself. Around 900 AD, a small group from the collapsing Mesoamerican world traveled north. They weren't refugees in any conventional sense. They arrived at Cho Canyon with knowledge, architectural knowledge, astronomical knowledge, religious knowledge. And within a few generations of their arrival, Cho transformed from a modest agricultural settlement into a coordinated theocratic center with a ruling dynasty that would hold power for nearly three centuries. A peaceful egalitarian farming community does not transform itself into a coordinated theocracy with monumental architecture overnight. The template at Chako looked increasingly like a smaller northern copy of the Mesoamerican theocratic model. But it came with something else. Something the archaeological record had been hinting at for decades, but that most researchers had been reluctant to name out loud. What the people of the Valley of Mexico brought with them wasn't just architecture and astronomy. It was a religion that required blood.

[00:13:11]The case no one wanted.

[00:13:13]Here is where I have to introduce you to a man named Christy Turner. Turner spent most of his career at Arizona State University in a cluttered office full of skeletal casts and forensic charts and the kind of photographs you do not show to people you have just met. For more than 30 years, he stood almost alone in trying to explain what the Cha Kuan bones were actually showing. And for most of those 30 years, his colleagues wished he would stop. Turner had trained as a forensic consultant. He had worked with American police investigating homicides. He knew what human bones looked like when they had been treated gently after death. And he knew what they looked like when they had been treated as something else. The first time he laid out the Chakawan skeletal collections on his examination table, he saw it immediately. The bones had been processed, dismembered, broken, burned, and scattered. and the damage on them matched with disturbing precision the damage he saw on the bones of animals that had been butchered for food. He spent the next three decades building a forensic checklist. A minimum of six criteria had to be present before he would even use the word cannibalism.

[00:14:21]Burning on the backs of skulls but not on the faces, consistent with a head being placed on a fire while the brain was still inside. Anvil abrasion, the scraping pattern left when a deflesched bone is smashed between two stones to extract marrow. Cut marks made by stone tools at the specific joint end points where tendons hold muscle to bone. And most damning of all, the systematic absence of vertebrae, the richest source of marrow in the human body, pulverized in nearly every processed assemblage.

[00:14:51]Applied to the chakan material, the checklist produced a result the field could not dismiss. Turner and his colleagues identified nearly 300 individuals across dozens of Chakawan sites whose remains met the full forensic criteria. Men, women, children, infants, processed identically to the way Chakawan hunters processed deer and rabbit. Even then, his colleagues pushed back hard. Processing didn't prove consumption. They said the bones showed butchering. They didn't show eating. A body could be dismembered for ritual punishment, for which execution, for any number of reasons that didn't involve a meal. And for more than 20 years, that gap between butchering and consumption was where the entire debate lived until 1997 when a single sample from a site called Cowboy Wash closed it forever.

[00:15:44]Proof at Cowboy Wash.

[00:15:47]At a small site in southwestern Colorado, excavators found the remains of seven individuals processed according to every one of Turner's six criteria.

[00:15:57]And in the hearth at the center of the community alongside the cooking vessels, they found something else. A coprolyte, desiccated human feces preserved by the dry desert climate deposited at the scene of the processing. That coprolyte ended up in the lab of Richard Marlor at the University of Colorado. Marlor was a biochemist. He had built a career on hard physical evidence and he understood the moment he looked at the sample exactly what it could prove. He designed an assay for a single protein, human myoglobin. Here is why that mattered.

[00:16:32]Myoglobin exists only in skeletal muscle. It is not present anywhere else in the human body. It is not present in the intestinal tract of someone who has eaten plants or animals. The only way human myoglobin can appear in human feces is if one human being has consumed the skeletal muscle of another. There is no other pathway. Marlor ran the test six times in triplicate with every possible control. Every result came back positive. He sat with the data for days before he was willing to say what it meant out loud. Cannibalism at cowboy wash was no longer a hypothesis. It was a biochemical fact. And once cowboy wash was accepted, the broader Chakan pattern fell into place. Roughly one in 50 skeletal remains from the Chakone world showed the full forensic signature. The geographic distribution mapped almost perfectly onto the geographic distribution of the great houses. 90% of the processed remains were found in or near Chakon ceremonial centers. The timing was even more precise. The cannibalism signature appeared in the archaeological record almost exactly when Choco rose and it vanished almost exactly when Choco fell. Cannibalism during peace time in a region with no evidence of widespread warfare in a climate of agricultural plenty concentrated in and around the ceremonial centers of a coordinated theocratic civilization. It wasn't starvation. It wasn't conflict. It was the signature of something organized.

[00:18:02]rule by terror. What emerged from all the evidence was a single picture. A small group had arrived at Choco from the collapsing Mesoamerican world sometime in the late 9th century. They had brought with them the ball courts and the colonated facades and the astronomical alignments. And they had brought with them the religion that had sustained Mesoamerican elites for centuries. A religion in which the universe required blood to function. A religion in which the consumption of human flesh performed by priests and sanctified by cosmic necessity was the ultimate expression of power over other human beings. In the valley of Mexico, this religion had been the foundation of social control for a thousand years.

[00:18:43]Elite priests consumed the bodies of sacrificed captives. The ceremony was public. The gods demanded it. And anyone who resisted the system would themselves become the next offering. Transplanted to the American Southwest, this religious model didn't require a large population of believers. It required a small, organized, ruthless elite and a terrorized local population willing to comply. The Anastasia in this reading were not the cannibals. They were the subjects, the victims, the population held in place for nearly three centuries by a ruling lineage that had imported a system of religious terror from a thousand miles away. The forensic record does not show communities routinely eating their dead. It shows concentrated catastrophic events. Entire families processed in a single night. Children killed alongside their parents. Bodies dismembered with ceremonial precision and left in the ceremonial rooms of great houses where everyone in the region would know what had happened. The purpose, Turner argued, was not food.

[00:19:42]The purpose was message. A terror campaign requires relatively few victims to subjugate a population of thousands.

[00:19:49]The threat did not need to be carried out often. It only needed to be credible. This is where the story becomes genuinely difficult to tell responsibly. The PBLO descendant communities, the Hopi and Zouri and Aoma and the Rio Grande Pueblo have contested this interpretation for decades. They have pointed out correctly that cannibalism accusations have been used throughout American history to dehumanize native peoples and they have insisted that whatever happened at Choco happened to their ancestors, not because of them. That distinction matters. The evidence supports exactly that framing.

[00:20:21]a small messoamerican derived elite, a terrorized local population, a theocratic system maintained through religious violence until it collapsed under its own contradictions. The cannibalism at Choco was not a feature of Pueblo and culture. It was a feature of what had been done to Puebloan culture by an imported ruling class that used a borrowed religion to hold power for 2 and 1/2 centuries. The Chakawan world was not built on consent. It was held together by terror. And terror, as every civilization that has ever relied on it eventually discovers, is a system with an expiration date. The collapse.

[00:20:59]Around 1150 AD, the expiration date arrived. The first signal came from the climate. Tree ring analysis across the four corners region which lets researchers reconstruct rainfall patterns yearbyear going back more than a thousand years shows that the warming trend that had sustained chakan agriculture for nearly three centuries broke in the middle of the 12th century between 1130 AD and 1180 AD the southwest entered a prolonged drought.

[00:21:27]The rainfall patterns that had allowed Ishkoan farmers to grow maze at altitudes that should never have supported it began to fail season after season. Chako had always been vulnerable to this. The canyon itself had no reliable water source. The great houses and the roads and the ceremonial centers had been sustained by an immense coordinated effort to move food and materials from the outlying regions into the ritual core. When the outlying regions could no longer produce surpluses, the ritual core lost the ability to feed itself. The tribute stopped flowing. The coordination broke down. And then the second signal appeared, the cannibalism signature, which had been present in the Chakawan archaeological record for more than 200 years begins to disappear almost exactly when the drought begins. The latest forensic assemblages that meet Turner's full criteria cluster tightly in the decades around 1150 AD. After 1180, they essentially stop appearing. The system that had produced those remains for a quarter of a millennium ceased to produce them at all. Something had ended. Whether the local population rose against the ruling elite, whether the priests themselves lost the religious authority that had allowed the system to function, or whether the entire coordinated theocracy simply dissolved under the pressure of a failing food supply. The archaeological record cannot say for certain. What it can say is that within a few decades of the drought's arrival, the great houses were being abandoned, not destroyed, not burned, abandoned. The residents walked away and left their homes standing. By 1200 AD, the depopulation of the canyon was well underway. By 1250, the outlying Chakuan communities were emptying. By 1300, the four corners region was effectively empty of human habitation. The roads that had stretched across 90,000 square miles were reclaimed by desert. This is the moment the textbook narrative settles on. The vanishing, the mystery, the lost civilization. And this is the moment where that narrative has always been wrong. They never vanished.

[00:23:25]The depopulation of Choco was not a disappearance. It was a migration. The people who had lived under the Chakawan system, who had survived whatever had happened in those great houses for 2 and 1/2 centuries, did not vanish into the desert. They moved south and east following the rivers that still ran along the Rio Grand down to the little Colorado to the Moses and the fertile valleys where farming was still possible in a drying climate. They carried with them the knowledge of agriculture and astronomy and masonry that had sustained their ancestors. And they left behind the ceremonial centers of a theocratic system that had stopped being worth preserving. For more than six centuries, the story of where those people went was told only in the oral traditions of their descendants. traditions that the academic world largely refused to treat as evidence. What ancient DNA has now done in studies completed over the last decade is confirm what those oral traditions had been saying all along.

[00:24:20]The Anastasia did not vanish. Their descendants have been living in plain sight the entire time. The genetic signal of the Chakan population stripped of the elite Mesoamerican outlier matches the modern Hopi, the Zouri, the Akoma, the Rio Grande Pueblo communities. direct biological continuity. The same lineage, the same people, the ones who built the great houses, endured the terror, and walked out of the canyon when the system collapsed. They are not lost. They are not gone. They are alive. The question was never where the Anastasia went. The question was why anyone ever believed they had gone at all. The oral traditions told the story accurately for 800 years. The archaeologists simply refused to listen. Ancient DNA did not rediscover the Anazi. It confirmed what had never actually been forgotten, except by the people who came later and decided the story needed an ending. The real mystery of the American Southwest is not what happened to the people who built Choco Canyon. It is how long it took the rest of us to notice they were still here.
