LARS WRITES: Please make sure everybody understands, that I haven't analyzed the hairs in any way - they might be orangutang hairs or something else interely. They were sent to me by a Danish guy who lived and worked as a tour guide in Indonesia for several years in the 1990's.
The hairs were given to him by an Indonesian friend, who claimed they were from an OP that were seen near the village where he grown up in eastern Sumatra. He just kept them as a fun souvenir, and had almost forgotten about them, when he read something on the web, that led him to the CFZ blog and my name. To quote: "You can keep them if you like - I have no idea if they have any scientific value, but let me know what you find."
