We had previously shown that Intelligent Design is the best causal explanation for origin of Life and Origin of complex information in the DNA.
However many people object to the scientific nature of this claim. They say that this claim is not scientific as the theory is not testable and does not offer any predictions like other scientific theories. However this is not true.
Like other historical scientific theories, Intelligent Design is tested by comparing the explanatory power of competing hypotheses against already known facts. This is exactly what Dr. Stephen Meyer has done in his book ‘Signature in the Cell: DNA and the Evidence for Intelligent Design’ as we have presented in our article.
Not only this, Intelligent Design, just like other scientific theories, also offers predictions that can be observed or tested by laboratory experiments. Since the Intelligent Design makes claims about what caused life to arise, it has implications for what life should look like.
Dr. Meyer provides no less than a dozen predictions of Intelligent Design in the chapter ‘Some Predictions of Intelligent Design’ and discusses each one of those in detail. Following is summaried list that he has mentioned in the end of the chapter1
• No undirected process will demonstrate the capacity to generate 500 bits of new information starting from a nonbiological source.
• Informational accounting will reveal that sources of active information are responsible for putatively successful computer-based evolutionary simulations.
• Future experiments will continue to show that RNA catalysts lack the capacities necessary to render the RNA-world scenario plausible.
• Informational accounting will reveal that any improvements in replicase function in ribozymes are the result of active information supplied by ribozyme engineers.
• Investigation of the logic of regulatory and information-processing systems in cells will reveal the use of design strategies and logic that mirrors (though possibly exceeds in complexity) those used in systems designed by engineers. Cell biologists will find regulatory systems that function in accord with a logic that can be expressed as an algorithm.
• Sophisticated imaging techniques will reveal nanomachines (turbines) in centrioles that play a role in cell division. Other evidence will show that malfunctions in the regulation of these machines are responsible for chromosomal damage.
• If intelligent design played a role in the origin of life, but not subsequently, prokaryotic cells should carry amounts of genetic information that exceed their own needs or retain vestiges of having done so, and molecular biology should provide evidence of information-rich structures that exceed the causal powers of chance, necessity, or the combination of the two.
• If a designing intelligence acted discretely in the history of life, the various subdisciplines of biology should show evidence of polyphyly.
• The fossil record, in particular, should show evidence of discrete infusions of information into the biosphere at episodic intervals as well as a top-down, rather than bottom-up, pattern of appearance of new fossil forms.
• If an intelligent (and benevolent) agent designed life, then studies of putatively bad designs in life—such as the vertebrate retina and virulent bacteria—should reveal either (a) reasons for the designs that show a hidden functional logic or (b) evidence of decay of originally good designs.
• If the flagellar motor was intelligently designed and the type-3 secretory system devolved from it, the genes that code for the bacterial flagellar motor should be older than those that code for the proteins in the T3SS, and not the reverse. Alternatively, if the T3SS and the flagellar motor arose by design independently, T3SS should have unique (nonhomologous) genes that are not present in the genome for the flagellar motor.
• The functional sequences of amino acids within amino acid–sequence space should be extremely rare rather than common.
One can read the details of these in the book, Signature in the cell: DNA and the Evidence for Intelligent Design.
Furthermore, Replying to a question on The Intelligent Design and Evolution Awareness (IDEA) Center, the author shows how some of the predictions of Intellgent Design are now beginning to be come true with latest scientific research.
David Klinghoffer in an article ‘Bionic Bees? A Prediction of Intelligent Design‘ also shows how another prediction of ID, namely ‘If life is designed much like a computer is designed, running not only what looks like but really is software, then I predict it should be possible to “scan” and “upload” the software from biological entities to manmade artifacts, which would then run it just as they would any computer program’ is now becoming a reality.
Thus we conclude that Intelligent Design, just as any other theory, is testable, and therefore offers a valid scientific explanation, that can be tested.
