Earlier excavations there, carried out under the direction of Prof. Naama Goren-Inbar of the Institute of Archaeology, showed that the occupants of the site – who are identified as being part of the Acheulian culture that arose in Africa about 1.6 million years ago -- had mastered fire-making ability as long as 790,000 years ago. This revelation pushed back previously accepted dates for man’s fire-making ability by a half-million years.
The Gesher Benot Ya’aqov site is located along the Dead Sea rift in the Hula Valley of northern Israel.
Dr. Nira Alperson-Afil, a member of Goren-Inbar’s team, said that further, detailed investigation of burned flint at designated areas in all eight levels of civilization found at the site now shows that “concentrations of burned flint items were found in distinct areas, interpreted as representing the remnants of ancient hearths.” This tells us, she said, that once acquired, this fire-making ability was carried on over a period of many generations. Alperson-Afil’s findings are reported in an article published in the most recent edition of Quaternary Science Reviews.
She said that other studies which have reported on the use of fire only verified the presence of burned archaeological materials, but were unable to penetrate further into the question of whether humans were “fire-makers” from the very early stages of fire-use.
“The new data from Gesher Benot Ya’akov is exceptional as it preserved evidence for fire-use throughout a very long occupational sequence. This continual, habitual, use of fire suggests that these early humans were not compelled to collect that fire from natural conflagrations, rather they were able to make fire at will," Alperson-Afil said.
The manipulation of fire by early man was clearly a turning point for man’s ancestors, Once “domesticated,” fire enabled protection from predators and provided warmth and light as well as enabling the exploitation of a new range of foods.
Said Alperson-Afil: “The powerful tool of fire-making provided ancient humans with confidence, enabling them to leave their early circumscribed surroundings and eventually populate new, unfamiliar environments.”For further information:

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
