Scientists uncovered how people's food sources and habits changed in response to the shifting climate conditions prior to the Younger Dryas climate change event.

“In this general region, there was a change from more humid conditions that were forested and with diverse sources of food for hunter-gatherers, to drier, cooler conditions when they could no longer subsist only as hunter-gatherers.”Archaeologists are widely aware of the settlement at Abu Hureyra for providing evidence of the earliest shift from foraging to farming.

The researchers stated in the study: “The village occupants left an abundant and continuous record of seeds, legumes and other foods.” According to a statement by scientists, fruits and berries disappeared from the diet during the cooler climate and pivoted towards domestic-type grains and lentils due to the dwellers' experimentation with early cultivation methods., began growing “founder crops” such as emmer wheat, einkorn wheat, hulled barley, rye, peas, lentils, bitter vetch, chickpeas, and flax.

This layer held elevated levels of platinum, nanodiamonds, and small metallic particles, suggesting extraordinarily high temperatures beyond the capability of human technology at that period, implying the occurrence of a cosmic collision.
