Tracking what EricS says re the "natural selection" metaphor... here is an
excerpt from the incipient book....

Natural Selection – The Thing That Explains Evolution

Darwin explains evolution as a result of Natural Selection, which invokes
the model of Artificial Selection, or as it was more simply called in
Darwin’s day *Selection*. It is important to note the language of Darwin’s
day, because it reminds us that Selection―the intentional breeding of
organisms to produce descendants with desired traits―was a process that
most people in Darwin’s time were quite familiar with.

You will recall that that a model is a situation we think we understand
well, which is invoked to explain unseen aspects of a situation we think we
understand less well. In Darwin’s day, there was much confusion over why
organisms should be adapted to their natural environments, but there was
little confusion about the process of selection and its effectiveness. This
creates awkwardness when we try to teach about evolution today, because,
when most of our students enter class, they know very little about how
breeding programs work. We start with students who understand neither how
breeders intentionally control the variation in generations of their stock,
nor how organisms become adapted to their environments, and we try to make
them familiar enough with the former to use it as a model in explaining the
latter. This leads to two possible problems: First, we may fail to get our
students familiar enough with the model itself. Second, even if we could be
certain that the students understood artificial selection sufficiently,
that would not guarantee that they understood Darwin’s application of the
model.

......    [dairy cow example]  .....

We use the example of dairy cattle to illustrate the selection model, but
what model did Darwin have in mind? Darwin was an avid pigeon breeder, and
pigeon-breeding was probably the model he had in mind when he came up with
the idea of natural selection. Alas, the cows make a better model for the
modern reader, who will find it quite intuitive why one might want a dairy
cow that produces more milk, but will likely find it mysterious why one
would favor, for example, a skinny pigeon whose throat inflates into a
globe large enough for the pigeon's beak to rest upon. (We authors find it
mysterious as well, though the aesthetic is oddly pleasing.)
