History of Agriculture Revealed

Open any history book and you’re likely to find that the practice of agriculture was invented 12,000 years ago in the Levant, an area in the Middle East that was home to some of the first human civilizations. But a new discovery recently made in Northern Israel seems to have shattered the myth on the advent of agriculture, offering up exciting evidence that trial plant cultivation, what we call agriculture, began far earlier – some 23,000-years-ago.

Researchers from Israel’s Tel Aviv, Bar-Ilan and Haifa Universities, with participation from Harvard, recently uncovered the first weed species at the site of a sedentary human camp on the shore of Israel’s Sea of Galilee, the location where prehistoric communities cultivated the first plants for human consumption.

“While full-scale agriculture did not develop until much later, our study shows that trial cultivation began far earlier than previously believed, and gives us reason to rethink our ancestors’ capabilities,” TAU’s Prof. Marcelo Sternberg said in a statement. “Those early ancestors were more clever and skilled than we thought.”

‘Our ancestors were more clever and skilled than we thought’

Though weeds are typically considered a threat or nuisance in contemporary farming, their presence at the site of the findings revealed the earliest signs of trial plant cultivation — some 11 millennia earlier than conventional historical thought regarding the onset of agriculture.

The site, which was built by fisher-hunter-gatherers, was found to be unusually well-preserved, having been charred, covered by lake sediment, and sealed in low-oxygen conditions — ideal for the preservation of plant material. Hence, weed species and harvesting tools found at the site provide clear evidence of early farming.

“This uniquely preserved site is one of the best archaeological examples worldwide of the hunter-gatherers’ way of life,” Sternberg says.

Prehistoric plant cultivation

The site bears the remains of six shelters and a particularly rich assemblage of plants. Upon retrieving and examining 150,000 plant specimens, the researchers determined that early humans there had gathered over 140 species of plants. These included 13 known weeds mixed with edible cereals, such as wild emmer (wheat), wild barley, and wild oats.
