A summary of some of the major differences between a wild and b domesticated wheat, most notably the loss of shattering and larger seeds in the latter wheat. In wild wheat, shattering leaves behind a smooth scar at the point of attachment, whereas domesticated wheat requires threshing to remove seeds (making them easier to harvest), leaving behind a rough scar.
