Ancient DNA reveals mysterious Indigenous lineage that lived in Argentina for nearly 8,500 years — but rarely interacted with others

The discovery of an ancient Indigenous lineage in central Argentina, which thrived for almost 8,500 years with limited interaction with other populations, sheds light on the complex tapestry of human history in South America. This genetic study not only reveals the existence of a previously unknown group but also emphasizes the importance of recognizing diverse Indigenous cultures that have shaped the continent's past. Such findings are crucial for understanding the dynamics of human migration and settlement patterns, as well as the rich heritage that continues to influence contemporary Indigenous identities.
