This little story is amazing because it is the OLDEST human bone found. Granted it was only one femur (leg bone) but it proved invaluable for what its genetics told us.

When they sent the DNA for testing they found a hidden secret in this old bone. If you’d like to find out what THEY found out you can listen here or read the article here.
