It need not be and isn't for those approaching it properly:
Let's review, shall we?
Intelligent design refers to a scientific research program as well as a community of scientists, philosophers and other scholars
There's the first lie, in the first sentence. There is no such
scientific research program. As Behe, one of the "inventors" of this "model", has literally admitted under oath during the Dover trial.
who seek evidence of design in nature.
This second part of the first sentence, tells you everything you need to know.
They
seek evidence of design. This means that they formed their conclusion
before they did the work. They are not
concluding design. They are assuming it before even asking the question.
The theory of intelligent design
Not a theory (in the scientific sense). Theories explain sets of facts within a well defined scope and are supported by all relevant evidence and, most importantly,
are testable and falsifiable.
As Behe admitted during the Dover trial, ID "theory" is about as scientific as astrology "theory".
holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. Through the study and analysis of a system's components, a design theorist is able to determine whether various natural structures are the product of chance, natural law, intelligent design, or some combination thereof.
Yet when asked to do so, not a single one of them can. Neither has ANY such study ever been published (or even only
submitted for publication) in any of the mainstream scientific journals.
In other words, this work simply has never been done to the extent of being scientifically viable and credible.
It is even so bad that these guys started
their very own "journals" so that they could publish their "papers" and agree with eachother and then call it "peer reviewed".
Intelligent design has applied these scientific methods to detect design in irreducibly complex biological structures
IRC has been debunked several times over. In fact, several of the structures that Behe in 1996 branded as being "irreducibly complex" have since then rationally be explained by identifying the evolutionary pathways by which those structures evolved.
Another thing which was admitted by Behe himself during the Dover trial - only to then repeat these PRATT's after the trial. Creationist Dishonesty at work, in all its glory.
In reality, IRC is no more or less then an argument from ignorance. "we don't know how this structure came to be naturally, therefor it is design" is what it amounts to. Nothing more or less.
, the complex and specified information content in DNA, the life-sustaining physical architecture of the universe, and the geologically rapid origin of biological diversity in the fossil record during the Cambrian explosion approximately 530 million years ago.
Which is explained through evolutionary biology and requires no "designer".
