Wheat has been cultivated for more than 10,000 years, beginning in the Fertile Crescent and arriving in the UK around 5,000 years ago. Genome evolution and modification. Three homoeologous genes from three sub-genomes (A, B, D) of hexaploid wheat all contribute to this trait through different means of functional evolution (hyper-functionalization, pseudogenization, and sub-functionalization) (Zhang et al., 2011). Mechanisms for chromosome evolution. Photo by Elizabeth Gibson. Origin of Wheat: Cultivation of wheat started after 8000 BC. However, this result has been questioned, and a robust phylogeny of wheat relatives is still lacking.
