Psychologically, I think Dawkins and his cohort are refugees from strict religious fundamentalist backgrounds who have retained many aspects of fundamentalist thinking while rejecting the religious part. They seem to think they've got it all figured out, but in many respects, their views are 100 years out of date, more in line with 19th century highly deterministic thinking about science and nature.
(What it does say is "Biologists are racking their brains trying to think what useful task this apparently surplus DNA is doing" and "The simplest way to explain the surplus DNA is to suppose that it is a parasite, or at best a harmless but useless passenger".)

> "The intervening two decades between that volume and this have seen a major technological revolution in the science of genetics. Just how do these breakthroughs affect Dawkins's ideas about the origin of diversity? The answer, apparently, is not at all. Dawkins's descriptions of genetic processes are facile and outdated. According to him, the power of natural selection is still "almost limitless" genes are still discrete entities with "a flintlike integrity" that remains unaffected by their environment from generation to generation."
Similarly, the relationship between Charles Darwin and modern evolutionary theory is about as distant as that between Isaac Newton and modern physics, which is another concept that the Dawkins crowd (in which I'd include Charles Murray, Sam Harris, etc.) seems uncomfortable with.
A few hours ago you were saying something completely wrong about the book and now you incorrectly act as an expert critic. I recommend you give it a reread (or a read) instead.

More recent discoveries point to the genome's 3D architecture as being critical to its function, and large chunks of non-coding DNA appear to play key roles in keeping it stable.
The point, however, is that Dawkins is not a scientist, he's just a rather fundamentalist-minded ideologue, and that's true for the whole "New Atheist" cohort.
