Are Native Americans Related to Asians? The DNA Evidence

Yes, Native Americans and Asian populations share deep ancestral roots. Genetic studies estimate that roughly 62 to 86% of Native American ancestry traces back to East Asian populations, with the remaining 14 to 38% coming from an ancient population that lived in what is now Siberia and had ties to both Asia and Europe. The connection stretches back tens of thousands of years, to a time when small groups of people crossed from northeastern Asia into the Americas over a now-submerged land bridge.

What DNA Reveals About the Connection

The most direct evidence comes from mitochondrial DNA, which is passed down through the maternal line. Native American populations carry four major genetic lineage groups, labeled A, B, C, and D. All four are shared with Asian populations. Groups A, C, and D appear in eastern Siberia, while populations in Tibet, central China, and Mongolia carry detectable levels of all four. The Altai people of south-central Siberia are one of the few populations outside the Americas that carry all five of the founding Native American lineage groups, including a rarer fifth one.

On the paternal side, Y-chromosome studies tell a similar story. One key lineage found in Native American men also appears in the Lake Baikal region of Siberia and in parts of Europe, pointing to shared male ancestors across a wide geographic range.

In 2014, a landmark genome study added an important wrinkle. Researchers sequenced DNA from a 24,000-year-old skeleton found near Mal’ta, a site in south-central Siberia. This individual belonged to an ancient population now called the Ancient North Eurasians, who were genetically distinct from modern East Asians and had ties to both Asian and European populations. The study estimated that 14 to 38% of Native American ancestry flows from this ancient group, with the majority still tracing to East Asian lineages. In other words, the ancestors of Native Americans were themselves a blended population, carrying genes from at least two distinct sources before they ever set foot in the Americas.

A 10,000-year-old skeleton found near Siberia’s Kolyma River provided even more confirmation. Its DNA showed a mix of East Asian and ancient North Siberian ancestry that closely resembles the genetic profile of Native Americans, making it the closest match to Indigenous American DNA ever found outside North America.

The Beringian Land Bridge

The physical path between Asia and the Americas was Beringia, a massive land bridge that connected present-day Siberia to Alaska. Recent research dates the bridge’s existence to between 36,000 and 11,000 years ago, a span that overlaps with the last ice age. At its peak, Beringia was not a narrow strip but a wide, cold grassland, hundreds of miles from north to south.

Archaeological evidence places humans in northeastern Siberia as early as 30,000 years ago, at the Yana Rhinoceros Horn Site. But the earliest confirmed human presence at the southern tip of South America dates to only about 15,000 years ago. That 15,000-year gap led researchers to propose what’s known as the Beringian Standstill model: the ancestors of Native Americans moved into Beringia thousands of years before entering the Americas but remained isolated there, possibly blocked by massive glaciers to the south and harsh conditions to the east. During that long isolation, which may have lasted up to 15,000 years, unique genetic mutations accumulated. These mutations are found throughout the Americas but not in Asia, which is exactly what you’d expect from a population that was cut off for thousands of years before expanding into a new continent.

Shared Physical Traits

One of the most studied physical traits linking Native Americans and Asian populations is the shape of the front teeth. Shovel-shaped incisors, where the backs of the upper front teeth have raised edges that form a scoop-like shape, are common in both groups but rare or absent in people of African and European descent. The trait is driven largely by a specific genetic variant called EDAR 1540C, which is widespread in Asian and Native American populations. The more copies of this variant a person carries, the more pronounced the shoveling. This single gene variant accounts for about 19% of the total variation in tooth shape, roughly a quarter of the trait’s overall heritability.

This dental pattern is part of a broader set of tooth characteristics called Sinodonty, which includes single-rooted upper premolars and three-rooted lower molars. Sinodonty is common across East Asia and the Americas, forming a physical trail that mirrors the genetic one.

Stone Tools Tell a Parallel Story

Archaeology reinforces the genetic picture. The oldest known site in Alaska, Swan Point, dates to about 14,000 years ago and contains stone tools from the Dyuktai tradition, a widespread tool-making culture that stretched from northern Japan to northern China to Lake Baikal. Dyuktai toolmakers produced small, precisely made microblades struck from specially prepared stone cores, along with distinctive oval-shaped bifaces (stones flaked on both sides).

The later Clovis culture, which appeared south of the ice sheets in North America after 13,500 years ago, shows telltale connections to Dyuktai. Both cultures produced similar large oval bifaces. At the Anzick burial site in Montana, where an infant was buried with Clovis artifacts, one of the grave goods was a giant oval biface that had been intentionally broken, a practice also documented in Dyuktai sites across Siberia. While Clovis people developed their own innovations, like fluted spear points, the underlying technology traces back to Siberian roots. Some researchers have argued for a European origin of Clovis tools, but the Siberian Dyuktai assemblages contain much more convincing precursors, including large blades and cores that closely resemble what Clovis toolmakers produced.

Language Links Across the Pacific

Even language may preserve traces of the connection. The Dené-Yeniseian hypothesis proposes that the Na-Dene languages of North America, which include Tlingit, Navajo, and dozens of Athabascan languages, are related to the Yeniseian languages of central Siberia. Linguist Edward Vajda identified systematic parallels between these language families, including shared patterns in consonants, vowels, and tones, as well as strikingly similar verb structures. He also found evidence for a shared ancient possessive prefix that appears in nouns, postpositions, and demonstratives in both language families. If the hypothesis holds, it represents one of only a few confirmed linguistic links between the Old World and the New.

A Surprising Australasian Signal

Not all of the ancestry in the Americas fits neatly into the East Asian picture. Some Indigenous groups in South America, particularly in the Amazon and along the Pacific coast, carry a faint genetic signal linking them to present-day populations in South Asia, Australia, and Melanesia. Researchers call this the “Population Y” signal (from “Ypikuéra,” meaning “ancestor” in Tupi). It was first identified in Amazonian groups but has since been found in Pacific coastal populations as well, suggesting it was more widespread than initially thought.

This doesn’t mean a separate wave of people came directly from Australia or Melanesia. Ancient DNA from South American remains around 10,000 years old shows only a weak version of this signal, suggesting it likely traces back to common ancestors who lived in northeast Asia and carried a broader mix of genetic ancestry than modern East Asian populations do today. The signal appears to have entered South America through the Pacific coastal route and then spread inland, which would explain why it hasn’t been detected in North or Central American populations studied so far.

The overall picture is clear: Native Americans descend primarily from East Asian populations who migrated through Siberia and across Beringia into the Americas. But that ancestry was never a single, simple line. It included contributions from ancient North Eurasian populations, a long period of isolation in Beringia where unique genetic identities formed, and possibly traces of even more distant population groups. The relationship between Native Americans and Asians is real and deep, but it played out over tens of thousands of years and across a geography that no longer exists.
