Ancient Stone Tools Rewrite Human Evolution Theories

Recent research by archaeologists Eiki Suga and Seiji Kadowaki from Nagoya University reveals that early humans in southern Jordan, between 70,000 and 30,000 years ago, demonstrated sophisticated decision-making in selecting stone materials for tool-making. Their study, published in the Journal of Paleolithic Archaeology, shows that these humans chose flint based on its properties, balancing ease of crafting with durability, indicating a higher level of cognitive and technological sophistication than previously thought. This finding enhances our understanding of human evolution and adaptation.
