Brad Arroyo+FollowViking DNA’s Wild HIV SecretTurns out, a gene mutation that helps people resist HIV actually popped up 9,000 years ago near the Black Sea—way before Vikings were even a thing!

Wild how our DNA holds secrets from thousands of years ago! #DNADetective #HIVResistance #AncientHistory #ScienceNews #Genetics #Science459154Share
