Humans Used ‘high-tech’ Glue As Early As 100,000 Years Ago | Zenger

Must Read

A recent study found that 100,000 years ago, early people were employing high-tech “glue” manufactured from a local conifer in Africa.

Early Homo sapiens used glue derived from indigenous Podocarpus trees in the Middle Stone Age to join stone implements to wooden spears. The substance, according to scientists, can only be created using an “elaborate” technique and has “outstanding” adhesive characteristics. In a collaborative study with Professor Edmund February from the University of Cape Town in South Africa, Dr. Patrick Schmidt and Ph.D. candidate Tabea Koch from the University of Tübingen in Germany laid out the production. The majority of the adhesives were found as residues on scrapers or stone blades that had been bonded to handles or spears at various Middle Stone Age sites in South Africa, according to Dr. Schmidt. The research team claims that the lack of use of more accessible adhesives by early modern people tens of thousands of years ago is evidence of their creativity and ingenuity.
