If you are curious about creationism and ID from a science perspective, this is a light quick read that will bring you up to date. Hafer reminds me of me. The odd bad joke; a serious load of contempt for IDers and their ilk; copious diagrams and white space use; several fun anecdotes; all make for a fast easy read.
This is a book about ID (Intelligent Design), the stupid idea that we, and everything else, was designed by a designer. Generally a god, and generally a Christian god (that is the stupid part). The basic premise of the book is this: If there is a designer, he or she should not quite their day jobs. If creationism is a pig, ID is a pig with lipstick. The "evidence" for design is called "irreducible complexity". The idea is that certain structures (like the eye) are irreducibly complex… if you take any part out, the whole structure fails. This, in turn creates probability arguments against evolution. This is not true… see below.
Creationism is religion. ID is creationism on the down low. In one famous legal case (Dover Area School District), IDers took a creationist text book and edited it, replacing "god" with "intelligent designer" everywhere. But they screwed up (in one case, "creator" became "cintelligent designer"); the judge saw through it; and they lost, bigly.
Figuring prominently in the book is The Discovery Institute, a Washington State group that does no research, has no labs, does no experiments, makes no predictions, states nothing in numbers, has never published a paper (OK… one, but the editor was bribed, and the paper withdrawn), and yet spews pseudoscience like a fire hose. The Discovery Institute wishes to discover nothing. It wishes to inject religion into your life and our society... by stealth. They demand equal time in text books simply because they think they deserve it. They shout about academic freedom where none exists (public schools instructors do not have any "academic freedom" whatsoever). They fight dirty by getting stealth pro-ID people on school boards, and when they get a majority, they pounce, changing curricula. The "institute" created the famous "Wedge" document that ultimately leaked, exposing them for the conniving frauds they are. The "institute" is following in the footsteps of Stalin, the last guy who tried to quash evolution. That resulted in mass starvation.
When the institute and guys like Behe (a big Kahoona in the ID game) invoke science, they get the science wrong… every single time. Flagella in bacteria is an example of ID that Behe likes to promote. He made statements about flagella in bacteria (specifically, he said that IFT or InterFlagella Transport is required, which is false). Ironically, Behe points to malaria as an creation example (where he again gets the science wrong), but malaria is particularly bad today precisely because it has become resistant over time. In other words, malaria has evolved!
The human body is a mess. Back aches, fallen arches, rotten teeth, bad eyes, useless/dangerous organs like the appendix; our gonads are in the middle of a sewer; lost faculties (like the ability to create Vitamin C, something my cat can do); and the list goes on. The map of our nerves and arteries looks like a Jackson Pollack painting. And let us not forget giving birth.
Women have had the shit end of the stick since the dawn of humanity. Child birth and motherhood has huge rewards, but the risks prior to modern medicine were enormous. Assuming she did not die, a mother might get a fistula after a long, hard birth. A fistula is an abnormal "tube" growth connecting the uterus to the bladder or bowel. They can be created by difficult deliveries. A thus stricken mother will leak feces or urine from her vagina forever. This is every bit as unhealthy and awful as it sounds. And a lousy design. One thing about evolution is this: it largely doesn't give a shit about you once you have reproduced.
This is just the beginning of the major flaws in the design of our bodies. And a designer was not involved. It was evolution what done it.
Nothing about our bodies, or anything else in biology makes sense without evolution. But this does not deter the anti-intellectuals at the Discovery Institute.
It is often said by the aforementioned idiots, "What use is half an eye?"
"Nothing" is the answer if you intend to cut a working eye in half. But the actual answer is: "A half-working eye is better than no eye at all". The eye argument has been well addressed. Even a single photo-sensitive "eye" spot on a bacteria is better than no eye at all. What is most amusing about it is that the alternative (a designer) would have us believe that god that designed several different eye types over the millennia, perfected them, and then designed the terrible human eye from scratch, forgetting all he had learned from the past.
The basic issue with the human eye is this: In cuttlefish, the blood vessels and nerves that service the eye lie under the retina; in people, the opposite is true. Those vessels and nerves obstruct light and vision by sitting on top of the retina and, because the still have to get out of the eye, they exit trough a hole we know as our "blind spot". Other kinds of similar issues arise over and over, such as repurposing a spine and hips for upright walking (this is not part of the book, but still applicable).
ID and creationism have been around a long time. The Scopes Monkey Trial was in 1925 (as I recall). Almost 100 years ago... and we are still having the same stupid argument with fanatics without reason. That last sentence can be parsed any way you like.
