In the ancient world, the East and West may have been linked by nomads. These were people who traveled with their herd animals in search of good feeding grounds.
That is the finding of new research about the ancient trade path known as the Silk Road. The recent findings were published in the journal Nature.
The study suggests that herders were not separated from the development of the great civilizations of Asia and Europe. Instead, they were important actors in forming the trade path that crossed the world's largest land mass.
The Silk Road was an ancient trade route that may have developed as early as 2,300 years ago. It was not really one road. Rather, it was a number of paths connecting many places between the cities of Xi'an, China, in the east and Genoa, Italy, in the west.
But traders traveling along this long land route faced a huge barrier standing in their way: the mountains of Central Asia.
These mountains include the Pamir and Tian Shan ranges. They are nearly as tall as the Himalayas, the world's highest mountain range.
Michael Frachetti is an anthropologist at Washington University in St. Louis. He was an author of the recent study.
He says those mountains were a "pretty scary barrier" to traders bringing goods through Central Asia.
Researchers have been looking for a long time for the routes ancient Silk Road traders used. They have often followed the easiest paths between cities along the way.
But Frachetti thought, "That makes sense if your destination is the other side." He asked the question, "But what if that's not your destination?"
The routes of herders suggest different Silk Road paths
Herding communities have lived in the mountains of Central Asia for thousands of years. They follow paths up and down the mountains to find food for their flocks as the seasons change.
"Their number-one priority isn't taking the easiest path," Frachetti says. "Their number-one priority is feeding their animals along the way."
As they traveled from pasture to pasture, they would meet, trade and even marry members of other communities. Their meetings are like festivals, he said. They meet, goods are exchanged and connections are formed.
Early on, Frachetti's research did not deal with the Silk Road. He studied herding communities in Kazakhstan.
He developed an idea of how, during ancient times, communities in that area moved through the mountains from the highlands in summer to the lowlands in winter.
He made maps of herding paths in these areas.
Comparing research shows links between trade and herding
Frachetti did not get a lot of interest in his earlier research.
"And people kind of smiled and said, ‘That's a nice way to think about herding.' And that's literally where it sat for 11 or more years."
Then, Tim Williams at University College London mapped 258 known Silk Road sites.
Frachetti and his colleagues compared their map of herding paths with Williams' map of Silk Road sites. He found that they matched well.
"There's kind of a moment of truth where you say, ‘Okay, how much do they intersect?' And the intersection was surprising," he said.
The research suggests that before traders crossed Asia in caravans, there was a network of interconnected communities through the mountains. This later became an important part of the Silk Road.
Dan Rogers is with the Smithsonian National Museum of Natural History. He says the new research is important in two ways.
He says it shows how traders got through mountains to help develop an important trade route. But it also changes ideas about nomads. The research creates a much more complex "picture" of Central Asia, he says.
Frachetti says the next step is to search for more evidence to connect the sites that both groups of researchers have found.
He calls the new findings "a model against isolationism." The Silk Road connected very different civilizations, Frachetti said. But it did this by bringing together nomads.
"Through interactions with culturally diverse populations, a greater aggregate civilization arose."
That, he said, is a pretty powerful idea.
