Scientists find human DNA over 2,000 years old in caves in Spain and Portugal

Scientists have unearthed human DNA dating back over 2,000 years in caves straddling the borders of Spain and Portugal, a find that could revolutionize our understanding of prehistoric human populations. The DNA samples, discovered on cave walls, provide a rare glimpse into the genetic makeup of ancient people who lived in the region millennia ago. This breakthrough could help fill gaps in the historical narrative and shed light on migration patterns, cultural interactions, and even the genetic links between ancient and modern humans. It's a significant step forward in piecing together the complex puzzle of human history.
