The People Who First Rode Horses

Somewhere around 3500 BC, on the vast grasslands of what is now northern Kazakhstan, a spotted horse stood in a corral. This horse had a genetic quirk—two copies of a gene that gave it a striking leopard-spotted coat. But that same gene came with a serious disadvantage: the horse was nearly blind at night.

On the open steppe, where wolves hunted and dangers lurked in the darkness, a night-blind horse would not survive long. Unless, that is, someone was protecting it.

This is one of the clues that archaeologists have pieced together to argue that the Botai people—a culture that thrived in Central Asia between roughly 3700 and 3100 BC—were among the first humans to domesticate the horse. The leopard-spotted horses of Botai couldn't have flourished in the wild. Someone valued them enough to keep them safe.

A Revolution in Human History

The domestication of the horse was one of the most transformative events in human history. Horses gave humans unprecedented speed and mobility. They revolutionized warfare, trade, communication, and the very shape of civilizations. For thousands of years, until the invention of the railroad, horses remained the fastest way to travel across land.

But where and when did this partnership begin?

For decades, archaeologists debated this question. The traditional view held that horses were first domesticated on the Pontic-Caspian steppe—the vast grasslands stretching from Ukraine to Kazakhstan—sometime around 2500 BC. But discoveries at Botai pushed this date back by roughly a thousand years, to around 3500 BC, making the Botai culture a prime candidate for where humans first learned to ride.

The Settlement at Botai

The Botai culture takes its name from its most significant archaeological site: a settlement called Botai, located on the Imanburlyq River, a tributary of the Ishim, in northern Kazakhstan. At its peak, this settlement contained at least 153 pit-houses—homes dug partially into the ground, a common construction method in the harsh steppe climate where winters could be brutal and building materials scarce.

The settlement was once even larger. River erosion has been slowly eating away at the site for millennia, destroying an unknown number of structures. Archaeologists are essentially racing against the water to uncover what remains.

Two other major Botai sites have been identified: Krasnyi Yar and Vasilkovka. Together, these settlements paint a picture of a surprisingly stable society—one that had made a remarkable transition from the nomadic life of their ancestors to something approaching permanent residence.

From Wanderers to Settlers

The cultures that preceded the Botai were classic nomadic hunter-gatherers. They followed herds of wild game across the steppe, never staying in one place for long, using tiny stone tools called microliths—small, precisely crafted blades that could be fitted into wooden or bone handles to create spears, arrows, and knives.

The Botai changed all this. They stopped wandering. They built permanent homes. And they developed a new toolkit—larger stone tools called bifaces, worked on both sides, more suited to a sedentary lifestyle.

What could possibly convince steppe nomads to give up their way of life and settle down?

Horses. An enormous number of horses.

A Diet of Horse Meat

The archaeological evidence at Botai sites is remarkable for one overwhelming feature: horse bones. Thousands upon thousands of horse bones, found in and around every settlement. The Botai people ate horses—lots of them. Horse meat appears to have been their primary source of protein, a dramatic shift from the varied game hunted by their nomadic predecessors.

But were these wild horses, hunted on the steppe? Or were they domesticated animals, kept in herds and bred for human use?

The evidence points increasingly toward domestication.

First, there are the corrals. Archaeologists found traces of enclosures near the settlements, along with remarkable concentrations of horse dung—the kind of accumulation you would expect from animals kept penned in one area, not from wild horses passing through.

Second, there are the horse bones themselves. Careful analysis revealed patterns of wear and deformation that are characteristic of horses bred in captivity rather than wild animals. The population structure of the bones—the ratios of young to old, male to female—also suggested managed herds rather than random hunting.

Third, and perhaps most intriguingly, there was the pottery.

Mare's Milk and What It Means

In 2009, researchers announced a finding that electrified the archaeological world. Chemical analysis of pottery fragments from Botai sites revealed traces of mare's milk—the milk of female horses.

This might seem like a small detail, but its implications are profound. You cannot milk a wild horse. Horses are not docile animals; mares will not stand still to be milked unless they have been trained to accept human contact from a young age. The presence of mare's milk on Botai pottery strongly suggested that these horses had been domesticated—raised by humans, accustomed to human handling, and managed in ways that allowed for milking.

This pushed the earliest evidence for horse domestication back to around 3500 BC, roughly a thousand years earlier than previous estimates.

However, science rarely offers simple answers. More recent studies have complicated this picture. Analysis of dental calculus—the hardite buildup on teeth that can preserve traces of ancient diets—from Botai individuals showed no evidence of dairy consumption. If the Botai people weren't drinking the mare's milk, what were they using it for?

One possibility: hand-rearing foals. Mare's milk could have been collected to feed young horses whose mothers had died or couldn't nurse. This would still indicate domestication—you don't hand-raise wild animals—but it would mean the relationship between humans and horses was different from what we first assumed.

Bits, Bridles, and Control

Perhaps the most compelling evidence for domestication comes from the horses' mouths—literally.

A 2018 study led by Peter de Barros Damgaard examined horse remains from Botai sites and found three distinct types of wear on tooth and jaw bones. These patterns are characteristic of damage caused by bits—the metal or bone pieces placed in a horse's mouth and connected to reins, allowing a rider to control the animal's movements.

If the Botai were using bits, they were controlling horses. They were riding them, or at least leading them with bridles. This is domestication in action.

Combined with the evidence of the leopard-spotted horses—animals whose survival depended on human protection—and the corrals full of accumulated dung, the case for Botai horse domestication is strong. These were not just hunters following wild herds. They were herders, managing horses as livestock.

A Genetic Twist

Here's where the story takes an unexpected turn.

When scientists sequenced the DNA of Botai horses and compared it to modern horses, they discovered something surprising: the Botai horses are not the ancestors of today's domestic horses.

Instead, the Botai horses are the ancestors of Przewalski's horse—a wild horse species that survives today in small numbers in Mongolia and Central Asia. Przewalski's horses (pronounced roughly "sheh-VAL-skee") are the only truly wild horses left on Earth, never domesticated. And the horses that the Botai kept are their forebears.

Modern domestic horses—the ones that pull carriages, race at Churchill Downs, and carry police officers through city streets—descend from a different population. They share only about 2.7% of their ancestry with the Botai horses.

What does this mean? It means that horse domestication probably happened more than once. The Botai domesticated one type of horse around 3500 BC, but that lineage did not give rise to the horses we know today. Somewhere else, perhaps somewhat later, another group of humans domesticated a different population of wild horses—and those are the ancestors of almost all modern horses.

The Botai were pioneers, but their experiment with horse domestication was a dead end, at least in terms of direct genetic descent. Their horses' descendants live on in the wild, not in our stables.

Life Without Metal

One of the striking features of the Botai culture is what they lacked: metal.

At the same time the Botai were building their settlements on the Kazakh steppe, other cultures across Eurasia were entering the Copper Age and the Early Bronze Age. They were smelting metals, casting tools and weapons, developing new technologies that would transform human societies.

The Botai did none of this. Despite being contemporaneous with metal-working cultures in other parts of the steppe, there is no evidence for metallurgy at Botai sites. Their tools were made from stone and bone—particularly horse bone, which they had in abundance.

This raises interesting questions. Were the Botai isolated from the technological innovations happening elsewhere? Did they lack access to ore deposits? Or did they simply not need metal tools, having developed a way of life that worked perfectly well without them?

Their pottery tells a similar story of functional simplicity. The vessels were unglazed, mostly grey in color, with simple shapes suited to storage and cooking. The decorations were geometric—hatched triangles, diamond shapes called rhombi, step patterns, punctate dots, and circles. Nothing elaborate, but distinctive enough that archaeologists can identify Botai pottery at a glance.

Who Were the Botai People?

The genetic ancestry of the Botai people has been extensively studied, and the results reveal a population with deep roots in Eurasia.

The Botai show strong genetic affinity to a group archaeologists call "Western Siberian hunter-gatherers"—people who lived in the Russian forest zone east of the Ural Mountains around 5000 BC. Both populations derived most of their ancestry from a very ancient source called "Ancient North Eurasians," with smaller contributions from populations to the east, in what is now East Asia.

There's also evidence for minor gene flow from European hunter-gatherer populations, though this contribution was small. Overall, the genetic data suggests that the Botai were part of a broad population complex stretching across Siberia and Central Asia, people who had been living in these regions for thousands of years before horse domestication began.

The paternal lineages found in male Botai individuals—the Y-chromosome haplogroups passed from father to son—include types still found today primarily in Central Asia and Siberia, particularly around the Altai region. This suggests genetic continuity in the region spanning thousands of years.

What Language Did They Speak?

The Botai left no writing, so we have no direct evidence of their language. But linguists have made some intriguing suggestions.

The Finnish linguist Asko Parpola has proposed that the Botai language cannot be conclusively identified with any known language family. This isn't surprising—languages can vanish completely, leaving no descendants or documentation. Most human languages that have ever been spoken are now extinct and unknown.

However, Parpola suggests that the Botai language may have left traces in other tongues through borrowed words. Specifically, he proposes that the Proto-Ugric word for "horse"—*lox—might be a loanword from the Botai language. If the Botai were among the first horse domesticators, it would make sense for neighboring peoples to borrow their word for this revolutionary new animal.

Not all linguists agree. Vladimir Napolskikh argues that the Ugric horse word comes instead from Proto-Tocharian, an ancient Indo-European language once spoken in what is now western China. The Tocharian word *l(ə)wa meant "prey" or "livestock"—a plausible source for a horse word.

Another proposal, advanced by the Czech linguist Václav Blažek, connects the Botai to the Yeniseian language family. The Yeniseian languages are a small group of languages spoken in central Siberia; Ket, spoken by a few hundred people along the Yenisei River, is the only one still surviving. Blažek suggests that the Yeniseian languages may have originated in the Central Asian steppe before migrating north into Siberia, and that the Botai might have spoken an early form of Yeniseian.

If true, this would have fascinating implications. Blažek points to possible loanwords related to horsemanship that might have passed from Yeniseian into Proto-Indo-European—including, remarkably, the Indo-European word for horse itself: *H₁ek̂wos (which gave us Latin equus, and eventually words like "equestrian"). The Yeniseian word for stallion, reconstructed as something like *ʔɨʔχ-kuʔs, has a similar shape.

Could the Indo-Europeans—whose languages include English, Spanish, Hindi, Russian, and most languages of Europe and South Asia—have learned their word for horse from the descendants of the Botai?

This remains speculative. Linguists continue to debate these proposals. But the possibility that the Botai language influenced words we still use today is tantalizing.

Dogs: The Other Domesticated Animal

Horses were not the only domesticated animals at Botai. Archaeological evidence indicates that the Botai also kept dogs.

This is less surprising than horse domestication. Dogs were the first animals domesticated by humans, with evidence of human-dog partnerships stretching back more than fifteen thousand years. By the time of the Botai, dogs had been living alongside humans for millennia.

Still, the presence of dogs at Botai is significant. It suggests that these people had a sophisticated understanding of animal husbandry. They knew how to breed animals, how to manage them, how to integrate them into human society. This expertise would have been essential for the more challenging task of domesticating horses.

The End of Botai

The Botai culture disappears from the archaeological record around 3100 BC. What happened to these pioneering horse herders?

We don't know for certain. The archaeological evidence simply fades away. The settlements were abandoned. The distinctive Botai pottery and tools stop appearing.

Several possibilities exist. Climate change may have made the steppe less hospitable. Other populations may have moved into the region, absorbing or displacing the Botai. Disease, drought, or conflict could have played a role.

Or perhaps the Botai simply changed. Cultures are not static; they evolve, blend with neighbors, adopt new practices, and develop into something new. The descendants of the Botai may have continued to live on the steppe, but in ways that archaeologists can no longer distinguish as "Botai."

What we do know is that their horses—or at least the wild descendants of those horses—survived. Przewalski's horses roam the Central Asian grasslands to this day, a living link to the animals that the Botai first brought under human control more than five thousand years ago.

Why the Botai Matter

The Botai culture offers a window into one of humanity's most important partnerships: the relationship between humans and horses. Whether or not their domesticated horses contributed to modern breeds, the Botai demonstrate that horse domestication was possible earlier than once believed—and that it may have happened independently in multiple places.

They also challenge our assumptions about technological progress. The Botai thrived without metal, without pottery that would impress a museum visitor, without many of the markers we associate with "advanced" cultures. Yet they accomplished something remarkable: they convinced one of the steppe's most powerful animals to work alongside them.

In the corrals of Botai, surrounded by horses with spotted coats and night-blind eyes, a new chapter in human history began. The horse would carry humanity across continents, into battles and explorations, toward new ways of life. And it started, at least in part, on the banks of a Kazakh river, in pit-houses dug into the grassland earth, more than five thousand years ago.
