The 24-year-old selling human bones

With a vast bone collection worth over $600,000 and a large social media following, Jon Pichaya Ferry is revitalising the field of osteology. During a visit to his warehouse in Brooklyn, New York, he gives us a glimpse into his collection and the fascinating findings he has discovered.

He explains the meaning of 'responsibly-sourced' human remains, and what osteology can tell us about people and history.
