Einkorn (Triticum boeoticum) is an ancient grain with a diploid number of 14 (2n = 14). Durum (Triticum turgidum) appeared later. Durum grains are larger and the plant is hardier

It has twice the genetic material of Einkorn (2n = 28 ) but contains basically the same chromosomes. Can you propose a hypothesis on how durum evolved?
