A campsite with a floor plan
On the banks of the paleo-Jordan River, the Acheulian site of Gesher Benot Ya'aqov (GBY) contains some of the earliest accepted evidence for the control of fire outside of Africa, dating back approximately 780,000 years. The site is a series of campsites but consists of at least 14 distinct archaeological horizons stacked in 34 meters of sediment, indicating repeated occupation by early hominins for over 100,000 years.
The most remarkable discovery at GBY is the presence of fire, but its systematic use. Archaeologists identified the locations of ancient hearths—no longer visible—by mapping the dense clusters of tiny, burned flint fragments. Analysis of these "phantom hearths" shows the spatial organization of daily life. Different activities were consistently performed in specific locations. For example, areas for flint knapping are distinct from zones where food was processed and consumed. This evidence points to a formalized concept of living space, an ability once thought to be exclusive to Homo sapiens.
The waterlogged conditions of the site, which sits on the shore of the ancient Lake Hula, led to the exceptional preservation of organic materials. This provides a detailed picture of the hominin diet and environment.
What was on the menu
The diet of the GBY hominins was diverse. Analysis of fish teeth, particularly from large, carp-like species, shows they were heated to temperatures suitable for cooking, and not burning in a wildfire. This is the oldest direct evidence of cooking. The remains also show consumption of crabs, turtles, fallow deer, and even elephants.
Plant foods were equally important. Researchers have identified 55 different taxa of edible plants, including seeds, fruits, vegetables, and nuts. Seven species of nuts were recovered, including wild olive, pistachio, and acorns. Many of these require a hard hammer to crack open, and the site has also yielded a collection of pitted stones that served as hammers and anvils for this exact purpose.
The variety of burned wood found in the hearths—including ash, willow, oak, and wild grape—suggests these early humans gathered whatever firewood was available along the lakeshore. The sheer amount of data from Gesher Benot Ya'aqov shows the advanced cognitive abilities and complex behaviors of the Acheulean people who lived there.
