(click on the picture to go back)
The Goat Grasses are a group of over 20 wild annual grasses found in areas with a Mediterranean climate from Spain to China. The one that hybridised with Wild Einkorn 30,000 or more years ago has not been positively identified, and may now be extinct, but is believed to have been similar to the one shown.

Wild Einkorn and this Goat Grass are both diploids, each with 14 chromosomes in their cells. The hybrid, created by natural pollination and chromosome duplication (amphiploidy), was Emmer, a tetraploid wheat with cells containing 28 chromosomes.
