One small finger bone is helping to challenge theories of human migration

One small finger bone is helping to challenge theories of human migration: A small fossil finger bone found at an archaeological site in Saudi Arabia is lending further credence to the idea that Homo sapiens migrated out of Africa much more than 60,000 years ago, according to Cosmos Magazine. Testing on the bone established that it is 90,000 years old, putting it among one of the world’s oldest fossils found outside of Africa.
