Over the years, the general view of anthropology was that early humans (closely associated with modern humans) first migrated from Africa to Eurasia about 1.8 million years ago. This timeline is based primarily on findings from the Dmanisi site in Georgia, suggesting that early humans will gradually spread and expand into new environments. However, new discoveries from the Romanian Graunechansitet have revealed that they may have challenged this established narrative and challenged Eurasia 200,000 years earlier than they previously believed.
This finding is based on meticulous examination of bones in animals with clear cut marks, and early humans are able to use and slaughter the tool before it is traditionally thought that early humans left Africa. Provides important evidence to show that. Bones dating back about 1.95 million years ago are the oldest known evidence of Eurasia's oldest known activity, bringing the Dmanisi site forward at a considerable margin.
Excavate evidence: cut mark bones and intentional slaughter
The discoveries published in Græunceanu, published in Nature Communications, were unexpected. Researchers from an international team led by Ohio University's Sabrina Curran were initially skeptical of what could be found in bones previously unearthed from the site in the 1960s. The bones that had been sitting in the collection for decades were eventually reconsidered after a routine check that discovered several cut marked bones showed the use of stone tools.
“In the beginning I didn't expect to find a lot,” Curran explained. “However, during a routine check on the collection, some cut mark bones were found. This led to further investigations with Dr. Briana Poviner of the Smithsonian Association and Dr. Michael Pante of Colorado State University, as well as different bones. Other clear marks were discovered across the area, suggesting intentional slaughter activity.”
These cut marks indicate that Hymonin uses tools to remove meat from animals. This is an action that provides new evidence of tool use much faster than previously thought. This discovery not only challenges established ideas about the timeline of human migration, but also acquires the skills necessary to survive in diverse and challenging landscapes, and how early humans adapt to the environment. It provides new insights into.
Disputes over the use of early tools
The field of paleontology is not without its controversial debate, particularly regarding the evidence of early human ancestors and their use of tools. Researchers often face skepticism, especially when it comes to evidence that pushes back the timeline of human evolution.
“The field of paleontology can be controversial,” says Claire Terff, an associate professor at the University of Arkansas. “People are really fired about human ancestors, and one ongoing discussion relates to the earliest evidence of tool use. For this reason, when you pass on another paleontologist of these bones, you say, “Oh, Yes, these are cut marks,” he said, so he takes very close attention to documenting the existence of these cut marks. But if they told them they came from Romania two million years ago, they would say, “No, that's not right.” ”
Meticulous documentation and analysis of cut marks was required to ensure reliability of the findings. The team's careful approach reflects the great importance of this finding in reconstructing early human evolution and understanding of migration. By reviewing cut marks as justification for human use of tools, the team provided a solid foundation for a revised timeline for human movement and survival.
