As scientists explore a new universe—the universe inside the cell—they are making startling discoveries of information systems more complex than anything ever devised by humanity's best minds. How did they get there, and what does it mean for the theory of evolution?

Two great achievements occurred in 1953, more than half a century ago.
The first was the successful ascent of Mt. Everest, the highest mountain in the world. Sir Edmund Hillary and his guide, Tenzing Norgay, reached the summit that year, an accomplishment that's still considered the ultimate feat for mountain climbers. Since then, more than a thousand mountaineers have made it to the top, and each year hundreds more attempt it.
Yet the second great achievement of 1953 has had a greater impact on the world. Each year, many thousands join the ranks of those participating in this accomplishment, hoping to ascend to fame and fortune.
It was in 1953 that James Watson and Francis Crick achieved what appeared impossible—discovering the genetic structure deep inside the nucleus of our cells. We call this genetic material DNA, an abbreviation for deoxyribonucleic acid.
The discovery of the double-helix structure of the DNA molecule opened the floodgates for scientists to examine the code embedded within it. Now, more than half a century after the initial discovery, the DNA code has been deciphered—although many of its elements are still not well understood.
What has been found has profound implications regarding Darwinian evolution, the theory taught in schools all over the world that all living beings have evolved by natural processes through mutation and natural selection.
Amazing revelations about DNA
As scientists began to decode the human DNA molecule, they found something quite unexpected—an exquisite 'language' composed of some 3 billion genetic letters. "One of the most extraordinary discoveries of the twentieth century," says Dr. Stephen Meyer, director of the Center for Science and Culture at the Discovery Institute in Seattle, Wash., "was that DNA actually stores information—the detailed instructions for assembling proteins—in the form of a four-character digital code" (quoted by Lee Strobel, The Case for a Creator, 2004, p. 224).
It is hard to fathom, but the amount of information in human DNA is roughly equivalent to 12 sets of The Encyclopaedia Britannica—an incredible 384 volumes" worth of detailed information that would fill 48 feet of library shelves!
Yet in their actual size—which is only two millionths of a millimeter thick—a teaspoon of DNA, according to molecular biologist Michael Denton, could contain all the information needed to build the proteins for all the species of organisms that have ever lived on the earth, and "there would still be enough room left for all the information in every book ever written" (Evolution: A Theory in Crisis, 1996, p. 334).
Who or what could miniaturize such information and place this enormous number of 'letters' in their proper sequence as a genetic instruction manual? Could evolution have gradually come up with a system like this?
