Archaeologists Find Evidence of the Earliest Human Agriculture

Study of plant remains on shores of Sea of Galilee show crop cultivation may have developed 23,000 years ago

Israeli archaeologists have uncovered dramatic evidence of what they believe are the earliest known attempts at agriculture, 11,000 years before the generally recognized advent of organized cultivation. The study examined more than 150,000 examples of plant remains recovered from an unusually well preserved hunter-gatherer settlement on the shores of the Sea of Galilee in northern Israel.

Previously, scientists had believed that organized agriculture in the Middle East, including animal husbandry and crop cultivation, had begun in the late Holocene period – around 12,000 BC – and later spread west through Europe. The new research is based on excavations at a site known as Ohalo II, which was discovered in 1989 when the water level in the sea of Galilee dropped because of drought and excessive water extraction.

Occupied by a community of hunter-gatherers at the height of the last ice age 23,000 years ago, it revealed evidence of six brush huts with hearths as well as stone tools and animal and plant remains. A series of fortuitous coincidences led to the site’s preservation. The huts had been built over shallow bowls dug by the occupants and later burned. On top of that a deposit of sandy silt had accumulated before the rising lake had left it under 4 metres of water.

The study looked for evidence of early types of invasive weeds – or “proto-weeds” – that flourished in conditions created by human cultivation. According to the researchers, the community at Ohalo II was already exploiting the precursors to domesticated plant types that would become a staple in early agriculture, including emmer wheat, barley, pea, lentil, almond, fig, grape and olive.

Significantly, however, they discovered the presence of two types of weeds in current crop fields: corn cleavers and darnel. Microscopic examination of the edges of stone blades from the site also found material that may have been transferred during the cutting and harvesting of cereal plants.

The site also revealed evidence of rudimentary bread making from starch granules found on scorched stones, and that the community may have been largely sedentary, with evidence of consumption of birds throughout the year, including migrating species.
