Wheat Germinating on Ice
This picture shows an experiment that illustrates the hardiness and virility of the wheat. It is obviously a plant that can germinate in an almost Arctic temperature. Yet the original home of wheat, so far as we know, was southwestern Asia. Such an experiment as this, however, suggests that the wheat has ancestors that grew far to the north.
