The theory of evolution, whether in Darwin's original form or in the modern form since the introduction of mutations, amounts, in the final analysis, to saying that the forms of all of the living creatures in the world have come about by chance. The obvious objection is that, in cases in which scientists can follow what is happening, intricate designs do not come about by chance. The author emphasizes this point by reference to the sand paintings made by some tribes of Indians. It might be claimed that, if sand of different colors were mixed and scattered at random, a painting might result. But nobody in his right mind would wait for such a thing to happen. Since living creatures are more intricate than any sand painting, how much less could they have come about by chance?
