Via further mutations, the hole turns into a cavity with a small opening — the pupil — creating a pinhole camera -like system. Gradually, the cavity fills with fluid, and extra parts get tacked on to better focus incoming light, such as the lens and cornea. From start to finish, a full-on eye can evolve in as little as , years, evolutionary biologists have estimated.
The wheel, on the other hand, is an irreducibly complex system: It must work perfectly to work at all. If wheels and axles are noncircular, ill-fitting, or the wrong relative diameters, they simply do not turn. The sophisticated carpentry required to fashion wheel-and-axle systems explains why humans didn't manage to invent them until the Bronze Age, when we were already casting metal alloys, constructing canals and sailboats, and even designing harps and other complex musical instruments.
Evolution can only build body parts in stages, but because a rudimentary, nonrotating proto-wheel provides no benefit whatsoever to an animal, the process of wheel development is destined to never begin. Now, we look at how Dawkins utilizes precedent ideas to talk about his point on evolution.
Actually, the whole concept of evolution that he talks about in this essay is antecedent because it is about the Darwinian Evolution and Darwinism. Here is where familiarity to daily life comes in. This concept of selfishness in animals also ties into Darwinism, so Dawkins makes a connection with his precedent idea as well.
Overall, I feel that this essay was well constructed with effective uses of analogies, examples, precedent ideas, and familiarity to daily life. In my opinion, this is a very powerful skill that any writer would crave for when convincing others since any idea would be most memorable when it seems natural. However, I thought that the writer was trying to use too many concepts to persuade the reader, and this created confusion.
On the first page, Dawkins is comparing animal abilities to human inventions, but changes his topic to evolution on the second page, and writes about bacteria and some mountain on the last pages. Although I can clearly see that the writer has put in a lot of time and effort to make his essay as connected and joined as possible, the variation of ideas were a bit too much for me to comprehend all at once.
