These are the findings of an interdisciplinary study by archaeologists from Leiden University in collaboration with other researchers. Neanderthals used fire to keep the landscape open and thus had a big impact on their regional environment. Archaeological research has actually been brought out at this quarry, Neumark-Nord, in the last few years, and along with a big amount of data about the early environment, plentiful traces of Neanderthal activities have actually been found. At the point in time when these Neanderthals turned up there, the closed forest made method for large open areas, in part due to fires.
Comparative research conducted by Leiden palaeobotanist Professor Corrie Bakels has actually shown that at comparable lakes in the area, where the very same animals roamed, but where there are no traces of Neanderthals, the thick forest plants stayed largely undamaged.
Hunter-gatherers triggered environments to change 125,000 years back. These are the findings of an interdisciplinary research study by archaeologists from Leiden University in cooperation with other researchers. Neanderthals used fire to keep the landscape open and thus had a huge influence on their local environment. The study was released in the journal Science Advances on December 15, 2021.

” Archaeologists have actually long been asking questions about the character and temporal depth of human intervention in our worlds ecosystems. We are increasingly seeing very early, generally weak signs of this,” says Wil Roebroeks, Archaeology teacher at Leiden University

These indications proved much more powerful in research at a lignite quarry near Halle in Germany. Historical research study has actually been performed at this quarry, Neumark-Nord, in the last couple of decades, and along with a big quantity of information about the early environment, plentiful traces of Neanderthal activities have actually been found. “Among other things, we discovered the remains of numerous slaughtered animals, surrounded by numerous stone tools and a big quantity of charcoal remains.”

Open for 2,000 years
The traces were found in what 125,000 years ago was a forest location where not only prey such as deer, horses, and livestock, however also elephants, lions, and hyenas lived. This blended deciduous forest stretched from the Netherlands to Poland. In a number of locations in the location were lakes, and on the edges of some of these, traces of Neanderthals have actually been found, Roebroeks discusses. At the point in time when these Neanderthals turned up there, the closed forest made method for large open areas, in part due to fires.

” The question is, obviously, whether it became open due to the fact that of the arrival of hominins, or whether hominins came due to the fact that it was open? We have discovered enough evidence to conclude that hunter-gatherers kept the area open for at least 2,000 years.” Comparative research conducted by Leiden palaeobotanist Professor Corrie Bakels has actually revealed that at comparable lakes in the location, where the exact same animals roamed, however where there are no traces of Neanderthals, the thick forest plant life stayed mostly undamaged.
” Hunter-gatherers werent simply “primal hippies” who wandered the landscape choosing fruit here and searching animals there.”– Wil Roebroeks
Till now it was normally believed that it was only when human beings used up farming about 10,000 years ago that they started to shape their environment, for circumstances by lowering trees to develop fields. However lots of archaeologists believe it started rather, on a smaller scale, and according to Roebroeks, Neumark-Nord is the earliest example of such intervention. The new research findings are not just important for archaeology, says Roebroeks, however likewise for disciplines included in nature remediation. “It likewise includes something to the behavioral spectrum of early hunter-gatherers. They werent just “primal hippies” who wandered the landscape selecting fruit here and searching animals there. They assisted shape their landscape.”

Significant effect of fire
A previous study by Roebroeks and his research group showed that understanding about fire was currently being given by hominins a minimum of 400,000 years earlier. “We shouldnt be amazed if in future research study we find traces that suggest that hominins had a significant effect on their environment much earlier, on a regional scale a minimum of.”
