Neanderthal glue from the North Sea
A flint tool covered with a tar-like substance has turned out to be a top scientific find. Research by a Dutch team of scientists showed the find to be a piece of birch tar that was extracted 50,000 years ago by Neanderthals using complex techniques. The tar was used as an adhesive to make it easier…

Neanderthals knew what they were doing when it came to making the oldest known glue
Adhesives are an incredibly important part of every day life. They help hold together everything from shoes and mobile phones to satellites in space. But we didn’t invent adhesives: Neanderthals did, to make handles for stone tools over 191,000 years ago. Leiden researchers now found that Neanderthals…

Fire came to Europe later than was thought
Early hominins probably lived in Europe for hundreds of thousands of years before using fire to alleviate the winter cold, to cook or to make tools. It was only in the period betwen 300,000 and 400,000 years ago that the first finds were made that indicate that people had the ability to control fire…

Shift in scientific consensus about demise of Neanderthals
It is still unclear how the Neanderthals died out. For long, one theory seemed most likely: the emergence of the highly intelligent Homo sapiens, or modern humans.
