Evolutionists rarely attempt to calculate the probability of chance
occurrence in their imagined evolutionary scenarios. While there is no way to measure the probability of chance occurrence of something as complex as the eye, there are ways to calculate the probability of the chance occurrence of individual protein molecules that are essential to life. Over a thousand different kinds of proteins have been identified in the human body, and each has a unique chemical composition necessary for its own particular function.
Proteins are polymers, whose chemical composition depends on the arrangement of many smaller subunits called amino acids. There are 20 different kinds of amino acids that are used to construct the proteins of all living organisms, including man. These amino acids are linked together end-to-end (like a string of beads) to form a single protein macromolecule. The average protein consists of a string of 500 amino acids. The total number of combinations of 20 different amino acids in such a string is, for all practical purposes, unlimited. Each protein in our body, however, must contain a specific sequence of amino acids if it is to function properly. It is the task of the genetic system in our cells to organize the assembly of the amino acids into precisely the right sequence for each protein.
Proteins have been called _informational_ macromolecules because their amino acid sequence spells out information, in much the same way as the letters of the alphabet can be arranged to form a sentence or paragraph. We can appreciate the improbability of randomly assembling one of the essential proteins of life by considering the probability of randomly assembling the letters of the alphabet to form even a simple
phrase in English.
Imagine if we were to try to spell out the 23 letters and spaces in
the phrase "THE THEORY OF EVOLUTION" by using the evolutionary principle of _chance_. We might proceed by randomly drawing characters from a Scrabble set consisting of the 26 letters of the alphabet plus a space (for a total of 27). The probability of getting any particular letter or space in our phrase using this method would be one chance out of 27(expressed as 1/27). The probability of getting all 23 letters and
spaces in the order required for our phrase can be calculated by
multiplying together the probability of getting each letter and space (1/27 x 1/27 x 1/27 -- for a total of 23 times). This calculation reveals that we could expect to succeed in correctly spelling our phrase by chance, approximately _once_ in eight hundred, million, trillion, trillion draws! If we were to hurry the process along and draw our letters at the rate of a billion per second, we could expect to spellour simple little phrase once in 26 thousand, trillion years! But even this is a "virtual certainty" compared to the probability of correctly assembling any one of the known biological proteins by chance! So, have any of you evolutionists ever pondered that? There's no way...It's high time people really look at the truth.
