Wild grasses of the Fertile Crescent became the first major cereal crops, the grains behind bread and beer.
See it on the Life map →What happened
Einkorn and emmer wheat and barley were 'founder crops' of the Fertile Crescent, along with lentils, peas, chickpeas, bitter vetch and flax. Wild grasses scatter their seeds when ripe; rare plants that kept seeds on the stalk were easier to harvest, so their seed got replanted. Over about 1,000–2,000 years, domestic forms took over. Bread wheat arose about 9,000–8,000 years ago, when farmed emmer crossed with a wild goatgrass near the Caspian Sea.
Why it matters
Wheat and barley fed the first villages and the civilizations of Mesopotamia, Egypt and Europe; wheat still supplies about a fifth of the calories people eat.
The evidence (fossils, genes, rocks)
Charred grains and seed-head fragments from sites such as Abu Hureyra and Jericho show non-shattering forms rising; DNA traces einkorn to wild stands in southeastern Turkey's Karacadağ hills.
Still debated
Whether domestication was a slow, unconscious process across many villages or faster and centered on one core area is still argued.

▸Agriculture begins began with Wheat & barley domesticatedWell established
The connection
The world's first farming began with cereals in the Fertile Crescent. People who had harvested wild wheat and barley for millennia began sowing them. Repeated harvest and sowing favored plants whose seeds stayed on the stalk, until domestic varieties emerged. These grains, with lentils, peas and flax, formed the first farming package.
When and how
Fertile Crescent, at sites such as Abu Hureyra (Syria), Jericho (West Bank) and Çayönü (Turkey), about 11,500–10,000 years ago.
The evidence
Charred seeds and spikelet bases show non-shattering ears increasing over time; much earlier, 23,000-year-old Ohalo II in Israel shows wild cereal gathering.
Debates and open questions
Whether small-scale cultivation at Ohalo II means trial farming began far earlier and failed in the unstable ice-age climate.
▸Rice domesticated was domesticated independently of Wheat & barley domesticatedWell established
The connection
Rice and wheat-barley are two independent experiments in domestication, roughly 7,000 km apart, with no contact. Yet farmers in both regions selected the same key trait: seeds that stay on the plant. That parallel, also seen in maize and millet, shows people everywhere favored similar traits in different wild grasses.
When and how
Fertile Crescent from about 11,500 years ago; lower Yangtze, China, from about 10,000 years ago; no evidence of contact between them.
The evidence
Different wild ancestors and separate early sites show independent origins; the non-shattering trait arose through mutations in different genes in each crop.
Debates and open questions
Why domestication began in both regions within a few thousand years after the ice age, after so long without farming; climate is the leading explanation.
