A study of 1,300 stone hand axes found at 80 Neanderthal sites in France, Germany, Belgium, Britain and the Netherlands shows that two cultural traditions existed among Neanderthals living in what is now northern Europe between 115,000 to 35,000 years ago.

Two separate hand axe traditions or designs existed – the Mousterian of Acheulean Tradition in a region now spanning south-western France and Britain and the Keilmessergruppen Tradition in Germany and further to the East, according to study author Dr Karen Ruebens from the University of Southampton, who reported the results in the Journal of Human Evolution. She also identified an area covering modern day Belgium and the Netherlands that demonstrates a transition between the two.
“In Germany and France there appears to be two separate hand axe traditions, with clear boundaries, indicating completely separate, independent developments,” Dr Ruebens commented.
“The transition zone in Belgium and Northern France indicates contact between the different groups of Neanderthals, which is generally difficult to identify but has been much talked about, especially in relation to later contacts with groups of modern humans.”
“This area can be seen as a melting pot of ideas where mobile groups of Neanderthals, both from the eastern and western tradition, would pass by – influencing each other’s designs and leaving behind a more varied record of bifacial tools.”
Neanderthals in the western region made symmetrical, triangular and heart-shaped hand axes, while during the same time period, in the eastern region, they produced asymmetrically shaped bifacial knives.

“Distinct ways of making a hand axe were passed on from generation to generation and for long enough to become visible in the archaeological record. This indicates a strong mechanism of social learning within these two groups and says something about the stability and connectivity of the Neanderthal populations,” Dr Ruebens said.
“Making stone tools was not merely an opportunistic task. A lot of time, effort and tradition were invested and these tools carry a certain amount of socio-cultural information, which does not contribute directly to their function.”
The analysis also reveals other factors which could have influenced hand axe design, such as raw material availability to Neanderthals, the function of their sites, or the repeated reuse and sharpening of tools – didn’t have an impact in this instance.
The study adds a new archaeological perspective on Neanderthal regionality, which is a concept also identified in studies of their skeletal and genetic features.
