Neanderthals came before modern man in the prehistoric timeline. And they made distinct types of tools from bone called “lissoirs”. These crude instruments were used to scrape hides and pelts thereby making them softer and more durable. The tools were discovered and after carbon dating found to be 51,000 years old. This was the time when Neanderthal man roamed the earth.
Now, modern man came on the scene close to this time as the former went extinct. It is supposed that Neanderthal man taught the modern species the art of making these smoothing tools. Discovered in Southwestern France, these tools are still used by some leather workers in various parts of the world.
The possibility is not so farfetched. As the two closely related humanoids overlapped on the time scale they most probably exchanged some customs and culture before parting ways. Modern man used pointed tools and then started using “lissoirs”. This trait can have no other source apart from their so-called poorer cousins, the Neanderthals.
The very fact that several millennia before modern human beings acquired these tools they were possessed by Neanderthals is in itself evidence of this transfer of heritage. Neanderthal man while not fully developed (he had ridges on his eyebrows and a sloping forehead) was the closest anthropologically to modern man. He was also the first prehistoric ancestor to develop religious rituals.
