Genomics Study Shows Early Asians Traveled over 20,000 Km From North Asia to South America
- Researchers at Nanyang Technological University in Singapore led a genomic investigation revealing that early Asian populations embarked on humanity’s longest prehistoric journey, traveling over 20,000 kilometers on foot across the Americas more than 100,000 years ago.
- This migration occurred through the Bering Land Bridge during the last Ice Age, with early settlers arriving at South America's northwest tip approximately 14,000 years ago after a journey spanning thousands of years.
- Once in South America, early migrants divided into at least four distinct groups—Andean, Amazonian, Chaco, and Patagonian—each evolving unique genetic traits while adapting to diverse environments.
- The research involved DNA analysis of 1,537 individuals representing 139 ethnic groups, and senior author Stephan Schuster noted that genetic variation is actually higher in Asian groups compared to European populations, challenging previous assumptions influenced by earlier sampling biases.
- The migration’s genetic bottleneck reduced diversity in immune-related genes, possibly explaining Indigenous communities’ vulnerability to diseases from later immigrants and highlighting the need for increased Asian representation in genetic research.

Asians made humanity's longest prehistoric migration and shaped the genetic landscape in the Americas
An international genomics study has revealed that early Asians undertook humanity's longest known prehistoric migration. These early humans, who roamed the earth over 100,000 years ago, are believed to have traveled more than 20,000 kilometers on foot from North Asia to the southernmost tip of South America. Scientists have mapped the unexpectedly vast genetic diversity of Asians, who make up more than half of the world's population. These findi…
New genomics study shows longest early human migration was from Asia, and it shaped the Americas
A new genomics study has revealed that the longest migration of early humans was from Asia more than 100,000 years ago, covering more than 20,000km on foot. The researchers say understanding this migration and modern genetic diversity can assist in developing better tools to deal with medicine and public health problems in modern populations. The journey took the ancient people from North Asia across the ice bridge that once spanned the Bering S…
From Asia to America: Genetics Reveals New Details of Humanity’s Longest Migration · Global Voices
One of the largest studies of populations traditionally ignored by genetics provides on Thursday new details on the longest human migration: from Asia to the extreme south of America. There, in Tierra del Fuego, Chile, Kawesqar, descendants of humans who have traveled further from the original continent of all humans, Africa, continue to live. The new study warns that the four large native groups of South America have suffered a population decli…
