Introduction

This Global News video discusses the discovery of an unknown human lineage in Colombia through the analysis of ancient DNA. The research reveals a previously unreported lineage from a migration through the Bering Strait, distinct from other known lineages in the Americas.

Key Takeaways

• Ancient DNA analysis reveals a previously unknown human lineage in Colombia. The lineage originates from the pre-ceramic period.
• This lineage is distinct from other previously reported lineages in the Americas. Comparisons with other American populations, both ancient and modern, failed to find a match.
• The findings suggest a distinct migration wave from the Bering Strait. While the broader migration across Bering Strait is known, this specific lineage represents a previously unknown branch.
• A significant morphological shift is observed between ancient Paleoamericans and later Amerindians. Paleoamericans had elongated skulls, robust features, and large teeth, contrasting with the broader, rounder skulls of later Amerindians.
