Ancient DNA Suggests Origins of Multiple Sclerosis in EU
A massive cache of ancient genomes has helped researchers trace the origins of a wide variety of the genetic traits that occur in modern Europeans. According to the ancient DNA, characteristics such as an increased risk of developing multiple sclerosis may have reached Europe more than 45,000 years ago in the genomes of people who migrated to the European continent in three distinct waves. The research findings suggest that differences in the dispersal patterns of ancient migrants may have resulted in some of the regional variation seen in specific traits, contradicting the theory that genetic differences could have have occurred…
