The advent of agriculture roughly 11,500 years ago in the Middle East was a milestone for humankind – a revolution in diet and lifestyle that moved beyond the way hunter-gatherers had existed since Homo sapiens arose more than 300,000 years ago in Africa.
Analysis of forms – or isotopes – of elements including carbon, nitrogen, zinc, sulfur and strontium in these remains indicated the type and amount of plants and meat they ate. Found at the site were remains from different edible wild plants including sweet acorns, pine nuts, pistachio, oats and legumes called pulses. The main prey, based on bones discovered at the cave, was a species called Barbary sheep.
