TED-ED: What can you learn from ancient skeletons? - Farnaz Khatibi
Ancient skeletons can tell us a great deal about the past, including the age, gender and even the social status of its former owner. But how can we know all of these details simply by examining some old, soil-caked bones? Farnaz Khatibi...
