If you paid any attention in history class, then you’ve definitely heard about a species called the Neanderthals. They lived in Eurasia about 40.000 years ago and despite being extinct for a long time, it turns out there is a certain tool that they left us as a heritage gift. One Tumblr user decided to share his discovery after learning about a tool called a lissoir, which is still used by leather-workers to this day.

Turns out, it was actually a leather-worker himself who helped the scientists to understand what this weird tool made out of bones was. After reading this post, other users started sharing examples of craftsmen helping scientists to answer historical questions. One of those examples revolves around Rembrandt, and a weird deformation around his ears, which was later discovered by a retired ear surgeon to be a result of a failed attempt at piercing the ear.
