What 3,000-year-old Egyptian wheat tells us about the genetics of our daily bread
India, Nov. 7 -- Researchers sequenced the genome of a 3,000-year-old sample of Egyptian emmer wheat; Comparisons with modern samples suggest a story of how the crop spread
Human societies need food - and that often means wheat, which was first cultivated more than 12,000 years ago. Today, around one in five calories consumed by humans is from wheat. Over this time, humans have moved wheat species around the globe and transformed them through cultivation and breeding.
Most wheat species have a hybrid origin. Their DNA has also revealed a complex history of further hybridisation, with modern varieties carrying large genomic chunks that originate from related species. In some cases, genetic material was probably exchanged between species ...
