Various Stages of Development
Here are corn-teosinte hybrids ranging all the way from the condition of the primitive parent to that of the cultivated descendant. The ears at the bottom show close resemblance to the original teosinte. Going from right to left in the picture, we see evidences of improvement all along the line, until finally a really presentable ear of corn appears at the left. The picture furnishes a striking illustration of the segregation of characters often to be observed in the various members of the same fraternity of a hybrid race.
