Scientists have uncovered a surprising new lineage of ancient hunter-gatherers who lived near the land bridge between North and South America around 6,000 years ago. The discovery offers fresh insights into how early humans spread across the continent.
The discovery, revealed through ancient DNA analysis, is reshaping the understanding of the peopling of the Americas.
Published in the journal Science Advances, the study describes a genetically distinct group of early humans who lived in the high-altitude plateaus near present-day Bogotá, Colombia.
This area, often considered the “gateway” to South America, now appears to have hosted a lineage not previously recognized in ancient or modern populations.

A Genetic Puzzle
This new lineage doesn’t match the genetic profile of ancient Native Americans from North America, nor does it align with ancient or contemporary South American populations. That makes their discovery particularly puzzling — and groundbreaking.
