Summary:
- This article discusses how a recent study of ancient Viking DNA has helped reveal that a key gene mutation that helps fight HIV emerged around 9,000 years ago near the Black Sea region.
- The gene mutation, known as CCR5-delta 32, provides resistance against HIV and other diseases. By analyzing DNA from ancient Viking remains, researchers were able to trace the origins of this mutation back thousands of years.
- Understanding the origins and spread of this important genetic adaptation can provide insights into human evolution and the history of infectious diseases like HIV. The findings suggest this mutation may have arisen as a defense against past epidemics in the region.
