Abstract excerpt

Here we illuminate the evolutionary trajectory of domesticated wheat through genomic analysis of 3,000-6,000-year-old grains excavated in the southern Levant. Our results identify these specimens as an early domesticated form closely related to wheat accessions from Ethiopia, the Arabian Peninsula and India. Genomic evidence supports a multi-stage domestication model centred on the non-shattering spike, requiring...
