Excerpt from The Evolution of Plants We will not go into the question how the cultivated forms came from the wild types - that is a long and involved story, always difficult and often impossible to unravel in detail. For example, the origin of Wheat, the most important to us of all cultivated plants, has long been a mystery, and is not yet fully cleared up. The Wheats have now been traced, as Dr. Stapf informs us, to four primitive types. The most important of the wild species (the original of the Hard Wheats and other forms) has only been recognised within the last few years as a weed growing on the slopes of Mount Hermon in Palestine; the wild form of the Soft Wheats is still unknown. But, whatever the difficulties, we at any rate I know that all cultivated plants have come from pre-existing wild forms by descent with modification. This, however, is Evolution, and we arrive at the conclusion that all those plants of which we know the origin have been evolved from other, different plants which existed before them.
