"The light at the center of every cell"

The human genome contains about 30,000 genes. Genes make molecules. Molecules make organisms.

How a mere 30,000 genes can make a creature as complicated as ourselves is still something of a mystery.

Here's how geneticist Enrico Coen puts it in his book, The Art of Genes: "The software, the program, is responsible for organizing hardware, the organism. Yet throughout the process, it is the organism in its various stages of development that has to run the program." In other words, the hardware runs the software, while at the same time the software is making the hardware.

Call it, if you want, the miracle of life, but only in the sense that everything that is natural is miraculous.
