Plant pitch is an adhesive.
It is extracted from birch bark using a technique developed by Neanderthals at least 200,000 years ago, which makes it the oldest known synthetic material.
Pitch was also used by Homo sapiens (anatomically modern humans) throughout prehistory. This adhesive was used in particular to fix a knapped stone blade to a thrusting spear, for Neanderthals, or to a spear, for Sapiens.
