The Answer

The question in this edition is:

What was one of the possible methods that Neanderthals used to produce the first glue?

The answer: Ash Mound

Neanderthals are often described as less intelligent than modern humans. But the image of Neanderthals is slowly changing. One piece of evidence for this is that they produced the first glue made by humans to hold together their weapons. The glue had the constancy of tar. A key question has been how did they produce the glue. One possible method is the Ash Mound method. The process consisted of rolling up a piece of birch bark, and covering it with ash and hot embers from a fire. After 20 minutes, small drops of tar were found when unrolling the bark. See how the glue was used and read more about Neanderthals production of the first glue.
