The Scientific Theory of Intelligent Design
Thought it might be a good idea to summarize what exactly ID is for the many laman who dogmatically and unquestionably follow Darwinian theory within these forums. Enjoy.

Upon observing and studying the earth and its inhabitants, it is quite apparent that it is comprised of a large amount of diverse organisms and systems. From the simplest of organisms in nature such as the one celled ameba, to the intricate systems of proteins and amino acids that make up DNA, it seems more often than not much of the processes that make up life have logical patterns to them.
Some believe that these complex systems originated from a series of random mutations and chemical processes gradually over the years. This philosophical belief system is the embodiment of the widely excepted scientific theory known as Evolution.
In recent years, however, many scientists are starting to question the validity of the widely accepted evolutionary theory, particularly the aspect of it that subscribes to complex organisms evolving from simpler organisms through random circumstances. These scientists suggest that it would mathematically improbable for randomness to initiate the start of any complex system. In lieu of Evolutionary theory, they adhere to a study which suggests that some form of intelligence designed these systems. This theory that describes life as being created by some form of intelligence is entitled Intelligent Design(ID), and it is one of the most controversial theories presented amongst the modern scientific community.
The concept of nature having a design to it is nothing new. Many liken it to the design theory that proceeded it entitled Creationism, which is exclusively based off of the Christian religion. Although many ID scientists are indeed Christian, the theory itself is not exclusively based on Christian doctrine nor is it based on the supernatural. Instead it is based on understanding the natural complexities that make up nature, and the impossibility of such perfect conditions to arise from random circumstance.
In 1802, theologian Whilliam Paley presented a theory entitled the Watchmaker Design Thesis. The following is an excerpt from his thesis:
In crossing a heath, suppose I pitched my foot against a stone, and were asked how the stone came to be there; I might possibly answer, that, for anything I knew to the contrary, it had lain there forever. ... But suppose I had found a watch upon the ground, and it should be inquired how the watch happened to be in that place; I should hardly think the answer, which I had before given. (1)
The “rock” in the thesis is representative of a simplistic organism, while the “clock” is representative of a complex one. Using this analogy, Paley was asserting that the more complex an object is, greater is the likely hood that the object was at some point intelligently created. As simple as his thesis may sound, this type of rationale is the basis behind modern design theory.
Biology is but one of the many modern scientific facets that have assisted in giving the design theory credibility. In 1996, biochemist Michael Behe devised a theory, which expanded upon Paley’s initial Watchmaker thesis. Behe described biological systems as being too complicated on a molecular level, or too irreducibly complex to be formed by random processes within an organism and its environment.
By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. (2)
Many biological systems are composed of codependent parts. Removing any part within these systems would cause them to not function properly, and in many cases not function at all. These irreducibly complex systems as Behe defines them, could not be reduced into simpler ones based on the dependency each part has with another. By adhering to Behe’s rationale, one would then have to attribute such a process as being part of a design, as opposed to being initiated from unplanned circumstances.
Modern concepts involving mathematics and statistics also shed new light on the validity of the design theory. Mathematician Whilliam Dembski suggests that it is statistically impossible to define complex organisms as the byproduct of random events. There are three core components to Dembski’s thesis. These components relate to the relationships of objects that are in a string, or a series of objects that have some form of coexistence. (3)
The first component, or contingency as Dembski terms it, relates to the freedom of choice objects within a string have. The second component, complexity, refers to the inability of a string’s creation to be defined by mere chance. (4)
Dembski asserts that one can only define a string’s creation as being unplanned if it is made up of very few contingent components. For example the word “an” can be thought of as a simple string. The words that make up a short story can be thought of as a complex string. It is somewhat probable to surmise that one can randomly throw two letters together on a page and create a simple word such as “an.” However, it is grossly illogical to assume that hundreds of letters can be thrown together at random on a page to create a story. The probability of the later string being generated from random circumstance would be around 10^-150, or in laman’s terms nearly
impossible. (5)
With such dramatic findings being presented, one can only conclude that the complexity of the string alludes to the third component of Dembski’s design theory being true. This third component or specification as he defines it, asserts that some type of intelligent pattern exists within the complex string and that the intelligence demonstrated within the pattern alludes to it being designed. (6)
Although ID greatly contradicts much of modern evolutionary theory on a philosophical level, there is one core belief that it shares with it. Microevolution, sometimes termed variation or adaptation, is generally the term used when describing this type of evolution. Examples of microevolution are represented in different species of dogs, cats, fish, and other organisms within a particular family. It is important to note, however, that ID does not support the concept known as macroevolution, which theorizes that species of different families at some point randomly evolved into species of another family. The existence of this type of evolution is widely debated between the proponents of both theories, and at this time no conclusive specimens have been found to confirm this type of evolution as being possible.
