The investigation of DNA preservation in archaeological human remains has opened up unprecedented opportunities for understanding the genetic history of our ancestors. This article explores the methods employed to preserve and extract DNA from ancient samples, along with the challenges and limitations encountered in the process. Various preservation techniques, such as cold storage and desiccation, are utilized to maximize DNA preservation. However, DNA degradation and contamination remain significant challenges. The extraction and analysis of ancient DNA involve specialized techniques such as PCR and whole-genome sequencing. The insights gained from ancient DNA analysis have revolutionized our understanding of migration patterns, genetic diversity, and the origins of specific traits. As technology advances, new methods offer the potential for even more detailed genetic information. Interdisciplinary collaborations and continued research hold promise for further unraveling the mysteries of our collective human history.
