For years, many archaeologists believed that the earliest Native Americans came from Japan, with the theory supported by similarities in ancient stone tools. This idea suggested that the Jomon people, who lived in Japan around 15,000 years ago, could be the ancestors of Indigenous Americans. However, new research is challenging this long-standing view, offering fresh insights into the complex migration patterns that led to the settlement of the Americas. A recent study published in PaleoAmerica presents evidence that points to Siberia, not Japan, as the most likely origin of the First Peoples. Let’s explore how this groundbreaking study is reshaping the story of human migration.
The Jomon Theory: A Long-Standing Hypothesis
For decades, archaeologists have argued that similarities in stone tools found across the Pacific provided strong evidence for human migration from Japan to the Americas. The theory suggested that these early populations, called the First Peoples, traveled along a coastal route, crossing the Bering Land Bridge to eventually populate North and South America. Supporters of the Jomon connection pointed to the likeness of stone artifacts made by the Jomon people in Japan and those found in early Indigenous American sites. But recent evidence is pushing this theory into question.
New Findings Challenge the Link
The latest study, led by Professor Richard Scott, an expert in human dental biology, throws doubt on the supposed connection between the Jomon and Native American populations. By analyzing tooth samples from populations across the Americas, Asia, and the Pacific, Scott’s team found strikingly little overlap between Jomon teeth and those of non-Arctic Native Americans. In fact, only 7% of the teeth showed any shared characteristics. According to Professor Scott, “The human biology simply doesn’t match up with the archaeological theory.”
Genetics Support the New Hypothesis
Genetic evidence is reinforcing these findings. Professor Dennis O’Rourke, co-author of the study, and a leading authority on Indigenous American genetics, highlighted that both maternal and paternal lineages from the Jomon and Native American populations show no overlap. Studies of ancient DNA now suggest that the two groups diverged from a common ancestor much earlier than originally thought. This revelation shifts the narrative and points to Siberia, rather than Japan, as the likely source for the First Peoples.
Reevaluating Human Migrations in Japan
Adding more complexity to the debate is recent research on the genetic makeup of the Japanese population itself. A study has revealed evidence of three distinct migration waves into Japan, as opposed to the previously accepted two. This new information challenges the idea that the Jomon population is genetically linked to Native American origins. Instead, it supports the notion that the Jomon people represent a separate population, distinct from the ancestors of Indigenous Americans.

Ancient Footprints: New Discoveries in New Mexico
Another compelling discovery, this time in New Mexico, adds another layer to the migration story. Archaeologists recently uncovered human footprints believed to be 23,000 years old, pushing back the timeline of human presence in North America. These footprints are considered solid evidence that humans were in the Americas long before the Last Glacial Maximum. However, these findings also do not support the idea that Indigenous Americans originated from Japan.
What About the Jomon DNA?
Despite the growing body of evidence, the study acknowledges the limitations of current data. The available Jomon DNA and dental samples, dating back less than 10,000 years, are relatively young compared to the Jomon population that lived 15,000 years ago. The researchers, however, argue that these samples are still valuable and represent proxies for earlier populations in Japan. As Professor Scott notes, the Incipient Jomon people—who lived 16,000 to 15,000 years ago—are unlikely to be the ancestors of Native Americans, especially when compared with other populations from Siberia.
A Shift in Our Understanding of Migration
The new research marks a turning point in our understanding of Native American origins and human migration to the Americas. For years, the theory that Native Americans descended from the Jomon people of Japan seemed plausible, but the latest findings suggest we need to reconsider that narrative. Although it is likely that the First Peoples reached the Americas via the Northwest Pacific coast, their origins appear to lie in Siberia, not Japan. This discovery calls for a reevaluation of how we understand the origins of the First Peoples and the complex routes that shaped human history.
Conclusion: The Search for the Truth Continues
While this study challenges the once-accepted theory of a Japanese connection, it’s clear that the full story of human migration is still unfolding. With new DNA and archaeological discoveries emerging regularly, the puzzle pieces are slowly coming together, but many questions remain. The latest findings show that science is always evolving, and with continued research, we may one day uncover the definitive answers about the origins of Native Americans and their ancestors.
