Close by were concentrations of burned seeds and wood, marking the location of early hearths. Scientists found debris from stone tool-making that had been scorched by fire at Gesher Benot-Ya’aqov. Why did they come together at these early hearths? -Perhaps to socialize, to find comfort and warmth, to share food and information, and to find safety from predators.Ī close look at the tiny pieces of flint in this photograph reveals that the flint has been deformed by fire-evidence of fire-making at Gesher Benot Ya’aqov 790,000 years ago. Early humans carried the tools from these distant places, probably stopping and using them along the way.īurned flint from the 790,000 year old site of Gesher Benot Ya'aquov, Israel.ĭuring this time period, at Gesher Benot Ya’aqov in Israel, early humans gathered around campfires that they made and controlled. Stone tools excavated from Kanjera chemically match rocks found at natural sources up to 12 km (7 mi) away. Smithsonian scientists, working at Kanjera with colleagues from Kenya and the United States, have excavated stone tools and butchered animal bones.ĭifferent rock types have different chemical compositions. There they made stone tools for butchering animals. Sharing vital resources with other members of the group led to stronger social bonds and enhanced the group’s chances of survival.Ībout 2 million years ago, early humans transported stone up to 12 km (7 mi) to a site at Kanjera, Kenya. Some groups of early humans began collecting tools and food from a variety of places and bringing them to favored resting and eating spots. Expanding social networks led, eventually, to the complex social lives of modern humans.
As brains became larger and more complex, growing up took longer-requiring more parental care and the protective environment of a home. Over time, early humans began to gather at hearths and shelters to eat and socialize. Sharing food, caring for infants, and building social networks helped our ancestors meet the daily challenges of their environments. Social bonds helped ensure humans' survival.
