Ancient DNA analysis reveals that northern Europeans have a higher risk of multiple sclerosis due to genetic legacy from horseback-riding cattle herders who arrived 5,000 years ago. Projectile points in Idaho dating back 16,000 years suggest early tool technology in the Americas. 10,000-year-old 'chewing gum' in Sweden provides insights into Stone Age teens' diet. Oldest known bead in the Americas, a 12,940-year-old hare bone tube, discovered in Wyoming. DNA from bones in a German cave indicates our species reached northern Europe 45,000 years ago during a cold climate.

Lethally sharp projectile points found along the banks of a river in southwestern Idaho, dated to nearly 16,000 years ago, could represent the oldest evidence of the first tool technology brought to the Americas. #ScienceMagArchives https://t.co/4YGTuRgzNj
Ancient DNA helps explain why northern Europeans have a higher risk of multiple sclerosis than other ancestries: It’s a genetic legacy of horseback-riding cattle herders who swept into the region about 5,000 years ago. https://t.co/Sf2jkQ7fZf
