It is pointed out that Darwin based his case very much on an alleged analogy between the facts that in nature some creatures have more offspring than others, and that a breeder arranges for creatures of the kind which he wants to have more offspring. In other words, he drew an analogy between the alleged natural selection, and selection as practiced by a breeder. However, the two cases are quite different in many respects, and there is no true analogy. Hence Darwin's arguments prove nothing.
