The Marriage of Science and <strong>Religion</strong> 201<br />

volcano on <strong>the</strong> verge of eruption after ga<strong>the</strong>ring energy during a long dormancy,<br />

evolution is a <strong>the</strong>ory waiting for revolution.<br />

This is not <strong>the</strong> place to describe <strong>the</strong> many technical objections to Darwinism<br />

that have been raised, but it is easy to describe <strong>the</strong>ir general tenor.<br />

Most of <strong>the</strong> difficulties are related to <strong>the</strong> way chance operates in complex<br />

systems. As systems increase in complexity, <strong>the</strong> chances of finding appropriate<br />

or viable variation at random plummets at an accelerating rate. Living<br />

organisms are enormously complex systems. Most people who are not<br />

ma<strong>the</strong>matically inclined have little grasp of <strong>the</strong> improbabilities involved.<br />

One still occasionally hears <strong>the</strong> assertion, often attributed to T. H. Huxley,<br />

that six monkeys randomly pounding away at typewriters could, given<br />

enough time, produce all <strong>the</strong> books in <strong>the</strong> British Museum. While this is<br />

literally true, <strong>the</strong> time required would make <strong>the</strong> age of <strong>the</strong> universe look<br />

like a nanosecond. Let us take an example somewhat less ambitious than<br />

<strong>the</strong> contents of <strong>the</strong> British Museum or <strong>the</strong> works of Shakespeare (also cited<br />

as a feasible product of simian labor). Consider <strong>the</strong> following sentence:<br />

In <strong>the</strong> beginning was <strong>the</strong> Word, and <strong>the</strong> Word was with God, and <strong>the</strong><br />

Word was God.<br />

This sentence contains seventy-nine discrete symbols, including letters,<br />

spaces, and punctuation. Let us say that <strong>the</strong> total number of choices is<br />

thirty: twenty-six letters (ignoring capitals), a space, period, question mark,<br />

and comma (for all o<strong>the</strong>r punctuation). A computer programmed to select<br />

symbols at random would have a chance of one in thirty of getting <strong>the</strong> first<br />

letter right and <strong>the</strong> same probability for each successive choice. So <strong>the</strong><br />

chance of getting <strong>the</strong> first word (two letters) right is 1/30 x 1/30 or 1/900.<br />

The probability diminishes exponentially with each new letter so where n<br />

= number of letters, <strong>the</strong> probability of getting <strong>the</strong> correct combination is:<br />

Or in <strong>the</strong> case of <strong>the</strong> sentence above:<br />

1<br />

30 n<br />

1<br />

30 79<br />

<strong>That</strong> gives a denominator, expressed in scientific notation, of 4.93x10 116 .<br />

The number of seconds in a year is 31,536,000 or 3.15x10 7 . The age of <strong>the</strong><br />

universe is presently thought to be about 15 billion or 1.5x10 10 years.
