A significant leap in technology occurred among early humans around 600,000 years ago, according to a team of anthropologists who have been examining ancient stone tools.
Associate Professor Charles Perreault from Arizona State University’s School of Human Evolution and Social Change, and Research Scientist at the Institute of Human Origins, has emphasized that the sudden and rapid advance in technology is credited to cumulative culture. This allowed ancient human populations to build on and recombine the solutions of previous generations, leading to the rapid development of new complex solutions to problems.
In a recent study published in the journal PNAS, Perreault and fellow author Jonathan Paige from the University of Missouri discovered a remarkable technological leap by analyzing stone tools dating back to 3.3 million years ago. The tools from the Middle Pleistocene period showed a sudden and unexpected increase in complexity, requiring up to 18 steps to manufacture.
The team observed that this newfound complexity and rapid transition towards cumulative culture likely had a significant impact on several aspects of early humans, including cultural and biological developments. Additionally, the evolution of technology during this period included controlled use of fire, wooden structures constructed with hafted tools, hearths, and other domestic spaces.
Paige and Perreault noted that their study of toolmaking is just one aspect of cumulative culture and suggested that further research could reveal other increases in similar behavioral developments that occurred in the past but may not be immediately evident in the archaeological record.
Their findings underscore how knowledge can be handed down from generation to generation, resulting in an ever-increasing and adaptive knowledge pool that drives cultural and technological evolution. The researchers concluded that this process has resulted in cultures that are too complex for individuals to invent on their own, requiring a collaborative and cumulative effort.
In light of this research, it becomes clear that the sudden and rapid technological advances around 600,000 years ago signalled a turning point in human history, leading to the development of complex social, foraging, and technological behaviors. The implications of this understanding of cumulative culture on the evolution of early humans are profound, providing invaluable insights into the course of our ancestors’ development.
This research highlights the remarkable impact of transferring ancient knowledge and how it has shaped the course of human civilization as we know it today. The dawn of cumulative culture brought about an era of rapid advancement, laying the groundwork for the extraordinary technological and cultural achievements of our species.
