New Tool Unlocks Family Trees Hidden in Ancient DNA
Researchers have released READv2, a faster and more accurate software for detecting biological relationships in archaeological DNA samples. The tool can identify relatives up to three degrees apart and distinguish between siblings and parent-child pairs—capabilities that help archaeologists reconstruct prehistoric social structures and family patterns, opening new avenues for understanding how ancient societies organized kinship and inheritance.

<p>The advent of genome-wide ancient DNA analysis has revolutionized our understanding of prehistoric societies. However, studying biological relatedness in these groups requires tailored approaches due to the challenges of analyzing ancient DNA. READv2, an optimized Python3 implementation of the most widely used tool for this purpose, addresses these challenges while surpassing its predecessor in speed and accuracy. For sufficient amounts of data, it can classify up to third-degree relatedness and differentiate between the two types of first-degree relatedness, full siblings and parent-offspring. READv2 enables user-friendly, efficient, and nuanced analysis of biological relatedness, facilitating a deeper understanding of past social structures.</p>
