Jan Bartek – AncientPages.com – A current archaeological examine carried out alongside the Jordan River banks, south of northern Israel’s Hula Valley, offers new insights into the dietary habits of early people, difficult conventional views on prehistoric diets.
The analysis signifies that historical hunter-gatherers closely relied on plant meals, significantly starchy vegetation, as a major vitality supply. Opposite to widespread perception that early hominid diets targeted primarily on animal protein, this examine reveals a various vary of plant-based meals of their weight loss program, together with acorns, cereals, legumes, and aquatic vegetation.

The multidisciplinary analysis facilities across the discovery of starch grains roughly 780,000 years previous from basalt instruments at an historical settlement web site close to Gesher Benot Ya’akov. This web site has yielded in depth proof, together with over 20 settlement layers and fossilized stays. The findings problem the prevailing notion that historical human diets have been primarily animal-based—a view typically supported by interpretations from animal bones discovered at archaeological websites the place plant stays are hardly ever preserved.

The examine was carried out as a part of Dr. Hadar Ahituv’s doctoral thesis at Bar-Ilan College’s Martin (Szusz) Division of Land of Israel Research and Archaeology. He’s now on the Laboratory for Historic Meals Processing Applied sciences (LAFPT), at Haifa College’s Zinman Institute of Archaeology. This collaborative analysis effort additionally concerned students from a number of establishments, together with Prof. Nira Alperson-Afil and Dr. Yoel Melamed from Bar-Ilan College, Prof. Naama Goren-Inbar from the Hebrew College, and Prof. Amanda Henry from Leiden College, Netherlands.
The presence of starch grains on historical instruments highlights the numerous position vegetation performed in early human diets. These grains recommend that starchy tubers and nuts wealthy in carbohydrates have been essential for assembly the vitality calls for required by the human mind. The examine additionally underscores refined strategies utilized by early people to course of plant supplies; starch grains have been found on basalt maces and anvils used for cracking and crushing varied vegetation.

Moreover, microscopic stays similar to pollen grains help these findings’ credibility. This analysis affords insights into social behaviors amongst early people; instrument use for processing vegetation implies cooperation inside bigger social teams and a deep understanding of their surroundings just like trendy people immediately.
This discovery marks an essential milestone in prehistoric research by offering helpful proof about our ancestors’ dietary habits whereas providing contemporary views on human evolution and societal growth.

“This discovery underscores the significance of plant meals within the evolution of our ancestors,” stated Dr. Ahituv. “We now perceive that early hominids gathered all kinds of vegetation year-round, which they processed utilizing instruments comprised of basalt. This discovery opens a brand new chapter within the examine of early human diets and their profound connection to plant-based meals.”
